Nothing will match it until the moon makes a similar approach on November 25 2034.

The regular daily and monthly rhythms of Earth’s only natural satellite, the Moon, have guided timekeepers for thousands of years. Its influence on Earth’s cycles, notably tides, has been charted by many cultures in many ages. The Moon moderates Earth’s wobble on its axis, leading to a relatively stable climate over billions of years.

The Full Moon By Vigdis Hocken

The Full Moon is the most spectacular Moon phase when the entire face of the Moon is lit up.
The Full Moon – Time and Datewww.timeanddate.com › astronomy › moon › full-moon

The Full Moon is the moment the entire face of the Moon is illuminated by the Sun’s rays. … 100% Illuminated … Most years have 12 Full Moons, 1 each month. … The symbol for Full Moon in modern calendars is a completely white circle.


Phases of the Moon: 2001 to 2100 Universal Time
Introduction Read and see all 100 year at: http://astropixels.com/ephemeris/phasescat/phases2001.html

The following table gives the date and time (Universal Time) of the Moon’s phases for 100 years. This data is of particular use to historical research projects.

The length of the mean synodic month (New Moon to New Moon) as calculated for the year 2000 is 29.530588 days (= 29d 12h 44m 03s). However, the length of any one synodic month can vary from 29.26 to 29.80 days due to perturbing effects of the Sun on the Moon’s eccentric orbit. For example, see Length of the Synodic Month: 2001 to 2100.

For conversion to time zones other than Universal Time, see Time Zones. If Daylight Saving Time is in effect, add one hour to the times listed.

Historians should note that the astronomical dating system used in these tables includes the year “0” while the traditional BCE – CE dating convention does not. Thus, the year “0” here corresponds to “1 BCE”, the year “-100” is “101 BCE”, and so on. The old style Julian calendar is used for dates prior to 1582 Oct 15, while the modern Gregorian calendar is used after that date. For more information, see calendar dates.

If an eclipse of the Sun or Moon takes place on a given date, it is indicated to the right of the date by a single character representing the type of eclipse. Abbreviations for the different types of eclipses appear below.

The supermoon of 14 November 2016 was 356,511 km (221,526 mi) away[1] from the center of Earth. This occurrence happens yearly with the next one in 2020, the previous being in 2018.[2]

The supermoon of 14 November 2016 was 356,511 km (221,526 mi) away from the center of Earth. This occurrence happens yearly with the next one in 2020, the previous being in 2018.

The full Moon of 22 October 2010, as seen through a 235 mm (9.25 in) Schmidt-Cassegrain telescope. This full Moon was near its northernmost ecliptic latitude (or northern lunistice), so the southern craters are especially prominent and cast shadows visible from Earth.

The full Moon of 22 October 2010, as seen through a 235 mm (9.25 in) Schmidt-Cassegrain telescope. This full Moon was near its northernmost ecliptic latitude (or northern lunistice), so the southern craters are especially prominent and cast shadows visible from Earth.

The full moon is the lunar phase when the Moon ap­pears fully il­lu­mi­nated from Earth‘s per­spec­tive. This oc­curs when Earth is lo­cated be­tween the Sun and the Moon (more ex­actly, when the eclip­tic lon­gi­tudes of the Sun and Moon dif­fer by 180°). This means that the lunar hemi­sphere fac­ing Earth – the near side – is com­pletely sun­lit and ap­pears as a cir­cu­lar disk. The full moon oc­curs roughly once a month.

The time in­ter­val be­tween a full (or new) moon and the next rep­e­ti­tion of the same phase, a syn­odic month, av­er­ages about 29.53 days. There­fore, in those lunar cal­en­dars in which each month be­gins on the day of the new moon, the full moon falls on ei­ther the 14th or 15th day of the lunar month. Be­cause a cal­en­dar month con­sists of a whole num­ber of days, a month in a lunar cal­en­dar may be ei­ther 29 or 30 days long.


A full moon is often thought of as an event of a full night’s du­ra­tion. This is some­what mis­lead­ing be­cause its phase seen from Earth con­tin­u­ously waxes or wanes (though much too slowly to no­tice in real time with the naked eye). By de­f­i­n­i­tion, its max­i­mum il­lu­mi­na­tion oc­curs at the mo­ment wax­ing stops. For any given lo­ca­tion, about half of these max­i­mum full moons may be vis­i­ble, while the other half oc­curs dur­ing the day, when the full moon is below the hori­zon.

Many al­manacs list full moons not only by date, but also by their exact time, usu­ally in Co­or­di­nated Uni­ver­sal Time (UTC). Typ­i­cal monthly cal­en­dars that in­clude lunar phases may be off­set by one day when pre­pared for a dif­fer­ent time zone.

The full moon is gen­er­ally a sub­op­ti­mal time for as­tro­nom­i­cal ob­ser­va­tion of the Moon be­cause shad­ows van­ish. It is a poor time for other ob­ser­va­tions be­cause the bright sun­light re­flected by the Moon, am­pli­fied by the op­po­si­tion surge, then out­shines many stars.

On 12 De­cem­ber 2008, the full moon was closer to the Earth than it had been at any time in the pre­vi­ous 15 years. This was re­ferred to in pop­u­lar media as a su­per­moon.

On 19 March 2011, there was an­other full “su­per­moon”, closer to the Earth than at any time in the pre­vi­ous 18 years.

On 14 No­vem­ber 2016, there was an­other full “su­per­moon”; this time it was closer to the Earth than at any time in the pre­vi­ous 68 years.


The date and ap­prox­i­mate time of a spe­cific full moon (as­sum­ing a cir­cu­lar orbit) can be cal­cu­lated from the fol­low­ing equation:{\displaystyle d=20.362000+29.530588861\times N+102.026\times 10^{-12}\times N^{2}}

where d is the num­ber of days since 1 Jan­u­ary 2000 00:00:00 in the Ter­res­trial Time scale used in as­tro­nom­i­cal ephemerides; for Uni­ver­sal Time (UT) add the fol­low­ing ap­prox­i­mate cor­rec­tion to d:-0.000739-(235\times 10^{-12})\times N^{2} days

where N is the num­ber of full moons since the first full moon of 2000. The true time of a full moon may dif­fer from this ap­prox­i­ma­tion by up to about 14.5 hours as a re­sult of the non-cir­cu­lar­ity of the Moon’s orbit. See New moon for an ex­pla­na­tion of the for­mula and its pa­ra­me­ters.

The age and ap­par­ent size of the full moon vary in a cycle of just under 14 syn­odic months, which has been re­ferred to as a full moon cycle.

Lunar eclipses

A full moon appears as a half moon during an eclipse moonset over the High Desert in California, on the morning of the Trifecta: Full moonSupermoonLunar eclipseJanuary 2018 lunar eclipse

When the Moon moves into Earth’s shadow, a lunar eclipse oc­curs, dur­ing which all or part of the Moon’s face may ap­pear red­dish due to the Rayleigh scat­ter­ing of blue wave­lengths and the re­frac­tion of sun­light through Earth’s at­mos­phere. Lunar eclipses hap­pen only dur­ing a full moon and around points on its orbit where the satel­lite may pass through the planet’s shadow. A lunar eclipse does not occur every month be­cause the Moon’s orbit is in­clined 5.14° with re­spect to the eclip­tic plane of Earth; thus, the Moon usu­ally passes north or south of Earth’s shadow, which is mostly re­stricted to this plane of ref­er­ence. Lunar eclipses hap­pen only when the full moon oc­curs around ei­ther node of its orbit (as­cend­ing or de­scend­ing). There­fore, a lunar eclipse oc­curs about every six months, and often two weeks be­fore or after a solar eclipse, which oc­curs dur­ing a new moon around the op­po­site node.

Full moons are tra­di­tion­ally as­so­ci­ated with in­som­nia (in­abil­ity to sleep), in­san­ity (hence the terms lu­nacy and lu­natic) and var­i­ous “mag­i­cal phe­nom­ena” such as ly­can­thropy. Psy­chol­o­gists, how­ever, have found that there is no strong ev­i­dence for ef­fects on human be­hav­ior around the time of a full moon. They find that stud­ies are gen­er­ally not con­sis­tent, with some show­ing a pos­i­tive ef­fect and oth­ers show­ing a neg­a­tive ef­fect. In one in­stance, the 23 De­cem­ber 2000 issue of the British Med­ical Jour­nal pub­lished two stud­ies on dog bite ad­mis­sion to hos­pi­tals in Eng­land and Aus­tralia. The study of the Brad­ford Royal In­fir­mary found that dog bites were twice as com­mon dur­ing a full moon, whereas the study con­ducted by the pub­lic hos­pi­tals in Aus­tralia found that they were less likely.

Full moon names

His­tor­i­cally, month names are names of moons (lu­na­tions, not nec­es­sar­ily full moons) in lu­niso­lar cal­en­dars. Since the in­tro­duc­tion of the solar Ju­lian cal­en­dar in the Roman Em­pire, and later the Gre­go­rian cal­en­dar world­wide, peo­ple no longer per­ceive month names as “moon” names. The tra­di­tional Old Eng­lish month names were equated with the names of the Ju­lian cal­en­dar from an early time (soon after Chris­tian­iza­tion, ac­cord­ing to the tes­ti­mony of Bede around AD 700).

Some full moons have de­vel­oped new names in mod­ern times, such as “blue moon“, as well as “har­vest moon” and “hunter’s moon” for the full moons of au­tumn.

Lunar eclipses occur only at a full moon and often cause a red­dish hue on the near side of the Moon. This full moon has been called a blood moon in pop­u­lar culture.

Harvest and hunter’s moons

A harvest moon. Its orange color is due to greater Rayleigh scattering as the moon appears close above the horizon, rather than being unique to harvest moons.[14]

A harvest moon. Its orange color is due to greater Rayleigh scattering as the moon appears close above the horizon, rather than being unique to harvest moons.

The “har­vest moon” and the “hunter’s moon” are tra­di­tional names for the full moons in late sum­mer and in the au­tumn in the North­ern Hemi­sphere, usu­ally in Sep­tem­ber and Oc­to­ber, re­spec­tively.

The “har­vest moon” is the full moon near­est to the au­tum­nal equinox (22 or 23 Sep­tem­ber), oc­cur­ring any­time within two weeks be­fore or after that date. The “hunter’s moon” is the full moon fol­low­ing it. The names are recorded from the early 18th century. The Ox­ford Eng­lish Dic­tio­nary entry for “har­vest moon” cites a 1706 ref­er­ence, and for “hunter’s moon” a 1710 edi­tion of The British Apollo, where the term is at­trib­uted to “the coun­try peo­ple” (“The Coun­try Peo­ple call this the Hunters-Moon.”) The names be­came tra­di­tional in Amer­i­can folk­lore, where they are now often pop­u­larly at­trib­uted to Na­tive Amer­i­cans. The Feast of the Hunters’ Moon is a yearly fes­ti­val in West Lafayette, In­di­ana, held in late Sep­tem­ber or early Oc­to­ber each year since 1968. In 2010, the har­vest moon oc­curred on the night of the equinox it­self (some 512 hours after the mo­ment of equinox) for the first time since 1991.

All full moons rise around the time of sun­set. Since the Moon moves east­ward among the stars faster than the Sun, lunar cul­mi­na­tion is de­layed by about 50.47 minutes (on av­er­age) each day, thus caus­ing moon­rise to occur later each day.

Due to the high lunar stand­still, the har­vest and hunter’s moons of 2007 were spe­cial be­cause the time dif­fer­ence be­tween moon­rises on suc­ces­sive evenings was much shorter than av­er­age. The Moon rose about 30 min­utes later from one night to the next, as seen from about 40° N or S lat­i­tude (be­cause the full moon of Sep­tem­ber 2007 rose in the north­east rather than in the east). Hence, no long pe­riod of dark­ness oc­curred be­tween sun­set and moon­rise for sev­eral days after the full moon, thus length­en­ing the time in the evening when there is enough twi­light and moon­light to work to get the har­vest in.

Farmers’ Almanacs

The Maine Farm­ers’ Al­manac from around the 1930s began to pub­lish Na­tive Amer­i­can “In­dian” full moon names. The Farm­ers’ Al­manac (since 1955 pub­lished in Maine, but not the same pub­li­ca­tion as the Maine Farm­ers’ Almanac) con­tin­ues to do so.

An early list of “In­dian month names” was pub­lished in 1918 by Daniel Carter Beard in his The Amer­i­can Boy’s Book of Signs, Sig­nals and Symbols for use by the boy scouts. Beard’s “In­dian” month names were:

  • January: Difficulty, Black Smoke
  • February: Raccoon, Bare Spots on the Ground
  • March: Wind, Little Grass, Sore-Eye
  • April: Ducks, Goose-Eggs
  • May: Green Grass, Root-Food
  • June: Corn-Planting, Strawberry
  • July: Buffalo (Bull), Hot Sun
  • August: Harvest, Cow Buffalo
  • September: Wild Rice, Red Plum
  • October: Leaf-Falling, Nuts
  • November: Deer-Mating, Fur-Pelts
  • December: Wolves, Big Moon

Such names have gained cur­rency in Amer­i­can folk­lore. They ap­pear in print more widely out­side of the al­manac tra­di­tion from the 1990s in pop­u­lar pub­li­ca­tions about the Moon. Mys­ter­ies of the Moon by Pa­tri­cia Had­dock (“Great Mys­ter­ies Se­ries”, Green­haven Press, 1992) gave an ex­ten­sive list of such names along with the in­di­vid­ual tribal groups they were sup­pos­edly as­so­ci­ated with. Had­dock sup­poses that cer­tain “Colo­nial Amer­i­can” moon names were adopted from Al­go­nquian lan­guages (which were for­merly spo­ken in the ter­ri­tory of New Eng­land), while oth­ers are based in Eu­ro­pean tra­di­tion (e.g. the Colo­nial Amer­i­can names for the May moon, “Milk Moon”, “Mother’s Moon”, “Hare Moon” have no par­al­lels in the sup­posed na­tive names, while the name of No­vem­ber, “Beaver Moon” is sup­pos­edly based in an Al­go­nquian lan­guage).

The in­di­vid­ual names (some in­con­sis­tent) given in Farm­ers’ Al­manac, which is not au­thor­i­ta­tive, in­clude the following:

  • January: “Wolf Moon” (for December in Beard 1918), “Old Moon”, “Moon After Yule”, “Winter Moon”
  • February: “Snow Moon”, “Hunger Moon”, “Storm Moon”
  • March: “Worm Moon”, “Crow Moon”, “Sap Moon”, “Crust Moon”, “Lenten Moon”, “Wind Moon”
  • April: “Seed Moon”, “Pink Moon”, “Sprouting Grass Moon”, “Pascal Moon”, “Egg Moon” (c.f. “Goose-Egg” in Beard 1918), “Fish Moon”, “Frog Moon”, “Spring Moon”, “Awakening Moon”, “Sap Moon”
  • May: “Milk Moon”, “Flower Moon”, “Corn Planting Moon”, “Grass Moon”, “Mother’s Moon”
  • June: “Mead Moon”, “Strawberry Moon” (c.f. Beard 1918), “Rose Moon”, “Hot Moon”, “Thunder Moon”
  • July: “Hay Moon”, “Buck Moon”, “Elk Moon”, “Summer Moon”, “Thunder Moon”
  • August: “Corn Moon”, “Sturgeon Moon”, “Red Moon”, “Barley Moon”, “Green Corn Moon”, “Grain Moon”, “Herb Moon”, “Wyrt Moon”, “Dog Moon”
  • September: “Harvest Moon”, “Corn Moon”, “Fruit Moon”, “Barley Moon”
  • October: “Hunter’s Moon”, “Blood Moon”, “Autumn Moon”, “Fall Moon”, “Sanguine Moon”, “Pumpkin Moon”, “Dying Moon”
  • November: “Beaver Moon”, “Turkey Moon”, “Frosty Moon”, “Dark Moon”
  • December: “Oak Moon”, “Cold Moon”, “Long Night’s Moon”

The Long Night’s Moon is the last full moon of the year and the one near­est the win­ter sol­stice.

“Ice Moon” is also used to refer to the first full moon of Jan­u­ary or February.

Hindu full moon festivals

In Hin­duism, most fes­ti­vals are cel­e­brated on aus­pi­cious days. Many of the Hindu fes­ti­vals are cel­e­brated on days with a full moon at night. Dif­fer­ent parts of India cel­e­brate the same day with dif­fer­ent names, as listed below:

  1. Chaitra Purnima – Gudi Padua, Yugadi, Ugadi, Hanuman Jayanti (April 15, 2014)
  2. Vaishakh Purnima – Narasimh Jayanti, Buddha Jayanthi (Buddha’s_Birthday) (May 14, 2014)
  3. Jyeshtha Purnima – Vat Savitri Vrat Vat Purnima (June 8, 2014)
  4. Ashadh Purnima – Guru Purnima, Vyas Purnima (important day for starting education and honoring teachers)
  5. Shravan Purnima – Good day for starting Upanayana day, Avani Avittam, Raksha Bandhan. Conceptually Onam also comes on this day.

Lunar and lunisolar calendars
The December 2015 full moon coincided with Christmas day.[32] This last occurred in 1977, with a Christmas Eve full moon between in 1996 and a full moon the day after Christmas in 2004 and before Christmas Eve in 2007 (both not shown here). A small horizontal libration is visible comparing their appearances. By the 19-year metonic cycle the full moon will repeat on Christmas day in 2034, 2053, 2072, and 2091.[33]

A small horizontal libration is visible comparing their appearances. By the 19-year metonic cycle the full moon will repeat on Christmas day in 2034, 2053, 2072, and 2091.Main article: Lunar calendar

Most pre-mod­ern cal­en­dars the world over were lu­niso­lar, com­bin­ing the solar year with the lu­na­tion by means of in­ter­calary months. The Ju­lian cal­en­dar aban­doned this method in favour of a purely solar reck­on­ing while con­versely the 7th-cen­tury Is­lamic cal­en­dar opted for a purely lunar one.

A con­tin­u­ing lu­niso­lar cal­en­dar is the He­brew cal­en­dar. Ev­i­dence of this is noted in the dates of Passover and Easter in Ju­daism and Chris­tian­ity, re­spec­tively. Passover falls on the full moon on 15 Nisan of the He­brew cal­en­dar. The date of the Jew­ish Rosh Hashana and Sukkot fes­ti­vals along with all other Jew­ish hol­i­days are de­pen­dent on the dates of the new moons.

Intercalary months

Main article: Intercalary month

In lu­niso­lar cal­en­dars, an in­ter­calary month oc­curs seven times in the 19 years of the Metonic cycle, or on av­er­age every 2.7 years (19/7). In the He­brew Cal­en­dar this is noted with a pe­ri­odic extra month of Adar in the early spring.

Blue moon

Further information: Blue moon

In the mod­ern sys­tem of “tra­di­tional” Amer­i­can full moon names tied to the sol­stice and equinox points, a su­per­nu­mer­ary full moon in such a pe­riod is called a blue moon. The term “blue moon” used in this sense may date to as early as the 16th cen­tury, but it be­came well-known in the United States due to the Farm­ers’ Almanac (pub­lished since 1818).

Ac­cord­ing to the pat­tern of use in the Farm­ers’ Almanac, a “blue moon” is the third full moon in any pe­riod be­tween ei­ther a sol­stice and an equinox, or be­tween an equinox and a sol­stice, (cal­cu­lated using the mean trop­i­cal year), which con­tains four full moons. These sea­sons are equal in length, un­like the as­tro­nom­i­cal ones, which vary in length de­pend­ing on the Earth’s speed in its el­lip­ti­cal orbit round the Sun. To com­pare, in 1983 the equal length sea­sons began at 1:48 am on 23 March, 9:15 am on 22 June, 4:42 pm on 21 Sep­tem­ber and 12:10 am on 22 De­cem­ber, while the as­tro­nom­i­cal sea­sons began at 4:39 am on 21 March, 11:09 pm on 21 June, 2:42 pm on 23 Sep­tem­ber and 10:30 am on 22 De­cem­ber (all times GMT).

Due to analy­sis of an in­ad­e­quate num­ber of old is­sues of the Farmer’s Almanac the au­thor of an ar­ti­cle in the March 1946 issue of Sky & Tele­scope mag­a­zine falsely con­cluded that a “blue moon” had been used in the sense of “the sec­ond full moon in any month which con­tains two full moons”. This mis­taken rule has been ad­mit­ted to be “er­ro­neous” in a 1999 Sky & Telescope ar­ti­cle, which gave the cor­rected rule based on order in seasons. Ac­cord­ing to ei­ther de­f­i­n­i­tion, “blue moons” occur with the av­er­age fre­quency of in­ter­calary months, seven times in 19 years, the Farm­ers’ Almanac sys­tem of full moon names ef­fec­tively defin­ing a lu­niso­lar cal­en­dar.

From Wikipedia, the free encyclopedia
A Spanish lunar calendar for  2017

A Spanish lunar calendar for 2017

lunar calendar is a cal­en­dar based on the monthly cy­cles of the Moon‘s phases (syn­odic months), in con­trast to solar cal­en­dars, whose an­nual cy­cles are based only di­rectly on the solar year. The most com­monly used cal­en­dar, the Gre­go­rian cal­en­dar, is a solar cal­en­dar sys­tem that orig­i­nally evolved out of a lunar cal­en­dar sys­tem. A purely lunar cal­en­dar is also dis­tin­guished from a lu­niso­lar cal­en­dar, whose lunar months are brought into align­ment with the solar year through some process of in­ter­ca­la­tion. The de­tails of when months begin varies from cal­en­dar to cal­en­dar, with some using newfull, or cres­cent moons and oth­ers em­ploy­ing de­tailed cal­cu­la­tions.

Since each lu­na­tion is ap­prox­i­mately 29 12 days (29 days, 12 hours, 44 min­utes, 3 sec­onds, or 29.530588 days), it is com­mon for the months of a lunar cal­en­dar to al­ter­nate be­tween 29 and 30 days. Since the pe­riod of 12 such lu­na­tions, a lunar year, is only 354 days, 8 hours, 48 min­utes, 34 sec­onds (354.367056 days), purely lunar cal­en­dars lose around 11 days per year rel­a­tive to the Gre­go­rian cal­en­dar. In purely lunar cal­en­dars, which do not make use of in­ter­ca­la­tion, like the Is­lamic cal­en­dar, the lunar months cycle through all the sea­sons of a solar year over the course of a 33 lu­nar-year cycle.

Al­though the Gre­go­rian cal­en­dar is in com­mon and legal use in most coun­tries, tra­di­tional lunar and lu­niso­lar cal­en­dars con­tinue to be used through­out the Old World to de­ter­mine re­li­gious fes­ti­vals and na­tional hol­i­days. Ex­am­ples of such hol­i­days in­clude Ra­madan (Is­lamic cal­en­dar); Easter; the Chi­neseJapan­eseKo­reanViet­namese, and Mon­go­lian New Year (Chi­neseJapan­eseKo­reanViet­namese, and Mon­go­lian cal­en­dars); the Nepali New Year (Nepali cal­en­dar); the Mid-Au­tumn Fes­ti­val and Chuseok (Chi­nese and Ko­rean cal­en­dars); Loi Krathong (Thai cal­en­dar); Sunuwar cal­en­dar; Vesak/Bud­dha’s Birth­day (Bud­dhist cal­en­dar); Di­wali (Hindu cal­en­dars); and Rosh Hashanah (He­brew cal­en­dar).



A lunar cal­en­dar was found at War­ren Field in Scot­land and has been dated to c. 8000 bc, dur­ing the Mesolithic pe­riod. Some schol­ars argue for lunar cal­en­dars still ear­lier—Rap­penglück in the marks on a c. 17,000 year-old cave paint­ing at Las­caux and Mar­shack in the marks on a c. 27,000 year-old bone baton—but their find­ings re­main controversial. Schol­ars have ar­gued that an­cient hunters con­ducted reg­u­lar as­tro­nom­i­cal ob­ser­va­tions of the Moon back in the Upper Palae­olithic. Samuel L. Macey dates the ear­li­est uses of the Moon as a time-mea­sur­ing de­vice back to 28,000-30,000 years ago.

Lunisolar calendars

Main article: Lunisolar calendar

Most cal­en­dars re­ferred to as “lunar” cal­en­dars are in fact lu­niso­lar cal­en­dars. Their months are based on ob­ser­va­tions of the lunar cycle, with in­ter­ca­la­tion being used to bring them into gen­eral agree­ment with the solar year. The solar “civic cal­en­dar” that was used in an­cient Egypt showed traces of its ori­gin in the ear­lier lunar cal­en­dar, which con­tin­ued to be used along­side it for re­li­gious and agri­cul­tural pur­poses. Pre­sent-day lu­niso­lar cal­en­dars in­clude the Chi­neseViet­nameseHindu, and Thai cal­en­dars.

Syn­odic months are 29 or 30 days in length, mak­ing a lunar year of 12 months about 11 days shorter than a solar year. Some lunar cal­en­dars do not use in­ter­ca­la­tion, such as most Is­lamic cal­en­dars. For those that do, such as the He­brew cal­en­dar, and Bud­dhist Cal­en­dars in Myan­mar, the most com­mon form of in­ter­ca­la­tion is to add an ad­di­tional month every sec­ond or third year. Some lu­niso­lar cal­en­dars are also cal­i­brated by an­nual nat­ural events which are af­fected by lunar cy­cles as well as the solar cycle. An ex­am­ple of this is the lunar cal­en­dar of the Banks Is­lands, which in­cludes three months in which the ed­i­ble palolo worms mass on the beaches. These events occur at the last quar­ter of the lunar month, as the re­pro­duc­tive cycle of the palo­los is syn­chro­nized with the moon.

Start of the lunar month

Lunar and lu­niso­lar cal­en­dars dif­fer as to which day is the first day of the month. In some lu­niso­lar cal­en­dars, such as the Chi­nese cal­en­dar, the first day of a month is the day when an as­tro­nom­i­cal new moon oc­curs in a par­tic­u­lar time zone. In oth­ers, such as some Hindu cal­en­dars, each month be­gins on the day after the full moon or the new moon. Oth­ers were based in the past on the first sight­ing of a lunar cres­cent, such as the He­brew cal­en­dar and the Hijri cal­en­dar.

Length of the lunar month

The length of each lunar cycle varies slightly from the av­er­age value. In ad­di­tion, ob­ser­va­tions are sub­ject to un­cer­tainty and weather con­di­tions. Thus to avoid un­cer­tainty about the cal­en­dar, there have been at­tempts to cre­ate fixed arith­meti­cal rules to de­ter­mine the start of each cal­en­dar month.

The av­er­age length of the syn­odic month is 29.530587981 days. Thus it is con­ve­nient if months gen­er­ally al­ter­nate be­tween 29 and 30 days (some­times termed re­spec­tively “hol­low” and “full”). The dis­tri­b­u­tion of hol­low and full months can be de­ter­mined using con­tin­ued frac­tions, and ex­am­in­ing suc­ces­sive ap­prox­i­ma­tions for the length of the month in terms of frac­tions of a day. In the list below, after the num­ber of days listed in the nu­mer­a­tor of the frac­tion in the first columns, an in­te­ger num­ber of months as listed in the de­nom­i­na­tor have been com­pleted; the sec­ond col­umn records the de­vi­a­tion ac­cu­mu­lated with re­spect to the true syn­odic month du­ra­tion and the time needed to achieve that de­vi­a­tion:

These frac­tions can be used to con­struct a lunar cal­en­dar, or in com­bi­na­tion with a solar cal­en­dar to pro­duce a lu­niso­lar cal­en­dar. A 49-month cycle was pro­posed as the basis of an al­ter­na­tive Easter com­pu­ta­tion by Isaac New­ton around 1700. The tab­u­lar Is­lamic cal­en­dar‘s 360-month cycle is equiv­a­lent to 24×15 months, minus a cor­rec­tion of one day.

In First Nations Culture
Turtle shell calendar

Turtle shell calendar

Na­tive amer­i­can tribes have used a tur­tle’s back pat­tern of scales to es­tab­lish the lunar cal­en­dar cycle. The pe­riph­eral scales sur­round­ing the edge add up to 28, the num­ber of days of a lunar cycle. The cen­ter of the shell com­prises thir­teen larger scales which rep­re­sent the 13 moons of a year.

In Popular Culture

Time travel in the Dark (TV se­ries) “oc­curs in in­cre­ments of 33 years be­cause the worm­hole is only ac­ti­vated when the sun and moon align.”

A full Moon sets behind San Gorgonio Mountain (in California) on a midsummer's morning.

full Moon sets behind San Gorgonio Mountain (in California) on a midsummer’s morning.

The lunar phase or Moon phase is the shape of the di­rectly sun­lit por­tion of the Moon as viewed from Earth. The lunar phases grad­u­ally change over the pe­riod of a syn­odic month (about 29.53 days), as the or­bital po­si­tions of the Moon around Earth and of Earth around the Sun shift.

The Moon’s ro­ta­tion is tidally locked by Earth’s grav­ity; there­fore, most of the same lunar side al­ways faces Earth. This near side is var­i­ously sun­lit, de­pend­ing on the po­si­tion of the Moon in its orbit. Thus, the sun­lit por­tion of this face can vary from 0% (at new moon) to 100% (at full moon). The lunar ter­mi­na­tor is the bound­ary be­tween the il­lu­mi­nated and dark­ened hemi­spheres.

Each of the four “in­ter­me­di­ate” lunar phases (see below) is around 7.4 days, but this varies slightly due to the el­lip­ti­cal shape of the Moon’s orbit. Aside from some craters near the lunar poles, such as Shoe­maker, all parts of the Moon see around 13.77 days of day­light, fol­lowed by 13.77 days of “night“. (The side of the Moon fac­ing away from Earth is some­times called the “dark side of the Moon”, al­though that is a mis­nomer).

Be­sides the Sun, the Moon is the most obvious
ob­ject in the sky. Bright, sil­very, with tantalizing
fea­tures on its face, it’s been the
tar­get of imag­i­na­tion, po­etry, science,
and even the oc­ca­sional rocket.
If you pay even the most cur­sory attention
to it, you’ll see that it changes every
day; some­times it’s up in the day, sometimes
at night, and its shape is al­ways changing.

The phases of the Moon as viewed looking southward from the Northern Hemisphere. Each phase would be rotated 180° if seen looking northward from the Southern Hemisphere. The upper part of the diagram is not to scale, as the Moon is much farther from Earth than shown here.

There are four prin­ci­pal lunar phases: new moon, first quar­ter, full moon, and last quar­ter (also known as third or final quar­ter), when the Moon’s eclip­tic lon­gi­tude is at an angle to the Sun (as viewed from Earth) of 0°, 90°, 180°, and 270°, respectively. Each of these phases ap­pear at slightly dif­fer­ent times at dif­fer­ent lo­ca­tions on Earth. Dur­ing the in­ter­vals be­tween prin­ci­pal phases are in­ter­me­di­ate phases, dur­ing which the Moon’s ap­par­ent shape is ei­ther cres­cent or gib­bous. The in­ter­me­di­ate phases last one-quar­ter of a syn­odic month, or 7.38 days, on average. The de­scrip­tor wax­ing is used for an in­ter­me­di­ate phase when the Moon’s ap­par­ent shape is thick­en­ing, from new to full moon, and wan­ing when the shape is thin­ning. The longest du­ra­tion be­tween full moon to new moon (or new moon to full moon) lasts about 15 days and 14.5 hours, while the short­est du­ra­tion be­tween full moon to new moon (or new moon to full moon) lasts only about 13 days and 22.5 hours.

  • New Moon appears higher on summer solstice than on winter solstice.
  • First Quarter Moon appears higher on spring equinox than on autumnal (fall) equinox.
  • Full Moon appears higher on winter solstice than on summer solstice.
  • Last Quarter Moon appears higher on autumnal (fall) equinox than on spring equinox.
  • Waxing Crescent Moon appears higher on mid-spring (May 5 in the Northern Hemisphere or November 7 in the Southern Hemisphere) than on mid-autumn (November 7 in the Northern Hemisphere or May 5 in the Southern Hemisphere).
  • Waxing Gibbous Moon appears higher on mid-winter (February 4 in the Northern Hemisphere or August 7 in the Southern Hemisphere) than on mid-summer (August 7 in the Northern Hemisphere or February 4 in the Southern Hemisphere).
  • Waning Gibbous Moon appears higher on mid-autumn (November 7 in the Northern Hemisphere or May 5 in the Southern Hemisphere) than on mid-spring (May 5 in the Northern Hemisphere or November 7 in the Southern Hemisphere).
  • Waning Crescent Moon appears higher on mid-summer (August 7 in the Northern Hemisphere or February 4 in the Southern Hemisphere) than on mid-winter (February 4 in the Northern Hemisphere or August 7 in the Southern Hemisphere).

Play mediaThis video provides an illustration of how the Moon passes through its phases – a product of its orbit, which allows different parts of its surface to be illuminated by the Sun over the course of a month. The camera is locked to the Moon as Earth rapidly rotates in the foreground.

Non-West­ern cul­tures may use a dif­fer­ent num­ber of lunar phases; for ex­am­ple, tra­di­tional Hawai­ian cul­ture has a total of 30 phases (one per day).

When the Sun and Moon are aligned on the same side of the Earth, the Moon is “new”, and the side of the Moon fac­ing Earth is not il­lu­mi­nated by the Sun. As the Moon waxes (the amount of il­lu­mi­nated sur­face as seen from Earth is in­creas­ing), the lunar phases progress through new moon, cres­cent moon, first-quar­ter moon, gib­bous moon, and full moon. The Moon is then said to wane as it passes through the gib­bous moon, third-quar­ter moon, cres­cent moon, and back to new moon. The terms old moon and new moon are not in­ter­change­able. The “old moon” is a wan­ing sliver (which even­tu­ally be­comes un­de­tectable to the naked eye) until the mo­ment it aligns with the Sun and be­gins to wax, at which point it be­comes new again. Half moon is often used to mean the first- and third-quar­ter moons, while the term quar­ter refers to the ex­tent of the Moon’s cycle around the Earth, not its shape.

When an il­lu­mi­nated hemi­sphere is viewed from a cer­tain angle, the por­tion of the il­lu­mi­nated area that is vis­i­ble will have a two-di­men­sional shape as de­fined by the in­ter­sec­tion of an el­lipse and cir­cle (in which the el­lipse’s major axis co­in­cides with the cir­cle’s di­am­e­ter). If the half-el­lipse is con­vex with re­spect to the half-cir­cle, then the shape will be gib­bous (bulging outwards), whereas if the half-el­lipse is con­cave with re­spect to the half-cir­cle, then the shape will be a cres­cent. When a cres­cent moon oc­curs, the phe­nom­e­non of earth­shine may be ap­par­ent, where the night side of the Moon dimly re­flects in­di­rect sun­light re­flected from Earth.

Orientation by latitude

In the North­ern Hemi­sphere, if the left (east) side of the Moon is dark, then the bright part is thick­en­ing, and the Moon is de­scribed as wax­ing (shift­ing to­ward full moon). If the right (west) side of the Moon is dark, then the bright part is thin­ning, and the Moon is de­scribed as wan­ing (past full and shift­ing to­ward new moon). As­sum­ing that the viewer is in the North­ern Hemi­sphere, the right side of the Moon is the part that is al­ways wax­ing. (That is, if the right side is dark, the Moon is be­com­ing darker; if the right side is lit, the Moon is get­ting brighter.)

In the South­ern Hemi­sphere, the Moon is ob­served from a per­spec­tive in­verted, or ro­tated 180°, to that of the North­ern and to all of the im­ages in this ar­ti­cle, so that the op­po­site sides ap­pear to wax or wane.

Closer to the Equa­tor, the lunar ter­mi­na­tor will ap­pear hor­i­zon­tal dur­ing the morn­ing and evening. Since the above de­scrip­tions of the lunar phases only apply at mid­dle or high lat­i­tudes, ob­servers mov­ing to­wards the trop­ics from north­ern or south­ern lat­i­tudes will see the Moon ro­tated anti-clock­wise or clock­wise with re­spect to the im­ages in this ar­ti­cle.

The lunar cres­cent can open up­ward or down­ward, with the “horns” of the cres­cent point­ing up or down, re­spec­tively. When the Sun ap­pears above the Moon in the sky, the cres­cent opens down­ward; when the Moon is above the Sun, the cres­cent opens up­ward. The cres­cent Moon is most clearly and brightly vis­i­ble when the Sun is below the hori­zon, which im­plies that the Moon must be above the Sun, and the cres­cent must open up­ward. This is there­fore the ori­en­ta­tion in which the cres­cent Moon is most often seen from the trop­ics. The wax­ing and wan­ing cres­cents look very sim­i­lar. The wax­ing cres­cent ap­pears in the west­ern sky in the evening, and the wan­ing cres­cent in the east­ern sky in the morn­ing.

When the Moon as seen from Earth is a thin cres­cent, Earth as viewed from the Moon is al­most fully lit by the Sun. Often, the dark side of the Moon is dimly il­lu­mi­nated by in­di­rect sun­light re­flected from Earth, but is bright enough to be eas­ily vis­i­ble from Earth. This phe­nom­e­non is called earth­shine and some­times pic­turesquely de­scribed as “the old moon in the new moon’s arms” or “the new moon in the old moon’s arms”.

Calendar Main article: Lunar calendar
May–June 2005 calendar of lunar phases

May–June 2005 calendar of lunar phases

The Gre­go­rian cal­en­dar month, which is 112 of a trop­i­cal year, is about 30.44 days, while the cycle of lunar phases (the Moon’s syn­odic pe­riod) re­peats every 29.53 days on av­er­age. There­fore, the tim­ing of the lunar phases shifts by an av­er­age of al­most one day for each suc­ces­sive month. (A lunar year lasts about 354 days.)

Pho­tograph­ing the Moon’s phase every day for a month (start­ing in the evening after sun­set, and re­peat­ing roughly 24 hours and 50 min­utes later, and end­ing in the morn­ing be­fore sun­rise) and ar­rang­ing the se­ries of pho­tos on a cal­en­dar would cre­ate a com­pos­ite image like the ex­am­ple cal­en­dar (May 8 – June 6, 2005) shown on the left. May 20 is blank be­cause a pic­ture would be taken be­fore mid­night on May 19 and the next after mid­night on May 21.

Sim­i­larly, on a cal­en­dar list­ing moon­rise or moon­set times, some days will ap­pear to be skipped. When moon­rise pre­cedes mid­night one night, the next moon­rise will fol­low mid­night on the next night (so too with moon­set). The “skipped day” is just a fea­ture of the Moon’s east­ward move­ment in re­la­tion to the Sun, which at most lat­i­tudes, causes the Moon to rise later each day. The Moon fol­lows a pre­dictable orbit every month.

Each of the four in­ter­me­di­ate phases lasts ap­prox­i­mately seven days (7.38 days on av­er­age), but varies slightly due to lunar apogee and perigee.

The num­ber of days counted from the time of the new moon is the Moon’s “age”. Each com­plete cycle of phases is called a “lu­na­tion“.

The ap­prox­i­mate age of the Moon, and hence the ap­prox­i­mate phase, can be cal­cu­lated for any date by cal­cu­lat­ing the num­ber of days since a known new moon (such as Jan­u­ary 1, 1900 or Au­gust 11, 1999) and re­duc­ing this mod­ulo 29.530588853 (the length of a syn­odic month). The dif­fer­ence be­tween two dates can be cal­cu­lated by sub­tract­ing the Ju­lian day num­ber of one from that of the other, or there are sim­pler for­mu­lae giv­ing (for in­stance) the num­ber of days since De­cem­ber 31, 1899. How­ever, this cal­cu­la­tion as­sumes a per­fectly cir­cu­lar orbit and makes no al­lowance for the time of day at which the new moon oc­curred and there­fore may be in­cor­rect by sev­eral hours. (It also be­comes less ac­cu­rate the larger the dif­fer­ence be­tween the re­quired date and the ref­er­ence date). It is ac­cu­rate enough to use in a nov­elty clock ap­pli­ca­tion show­ing lunar phase, but spe­cial­ist usage tak­ing ac­count of lunar apogee and perigee re­quires a more elab­o­rate cal­cu­la­tion.

Effect of parallax

The Earth sub­tends an angle of about two de­grees when seen from the Moon. This means that an ob­server on Earth who sees the Moon when it is close to the east­ern hori­zon sees it from an angle that is about 2 de­grees dif­fer­ent from the line of sight of an ob­server who sees the Moon on the west­ern hori­zon. The Moon moves about 12 de­grees around its orbit per day, so, if these ob­servers were sta­tion­ary, they would see the phases of the Moon at times that dif­fer by about one-sixth of a day, or 4 hours. But in re­al­ity, the ob­servers are on the sur­face of the ro­tat­ing Earth, so some­one who sees the Moon on the east­ern hori­zon at one mo­ment sees it on the west­ern hori­zon about 12 hours later. This adds an os­cil­la­tion to the ap­par­ent pro­gres­sion of the lunar phases. They ap­pear to occur more slowly when the Moon is high in the sky than when it is below the hori­zon. The Moon ap­pears to move jerk­ily, and the phases do the same. The am­pli­tude of this os­cil­la­tion is never more than about four hours, which is a small frac­tion of a month. It does not have any ob­vi­ous ef­fect on the ap­pear­ance of the Moon. How­ever, it does af­fect ac­cu­rate cal­cu­la­tions of the times of lunar phases.


File:Orbit of the Moon in 2013.ogvPlay mediaThe lunar phase depends on the Moon’s position in orbit around the Earth and the Earth’s position in orbit around the sun. This animation (not to scale) looks down on Earth from the north pole of the ecliptic.

It might be ex­pected that once every month, when the Moon passes be­tween Earth and the Sun dur­ing a new moon, its shadow would fall on Earth caus­ing a solar eclipse, but this does not hap­pen every month. Nor is it true that dur­ing every full moon, the Earth’s shadow falls on the Moon, caus­ing a lunar eclipse. Solar and lunar eclipses are not ob­served every month be­cause the plane of the Moon’s orbit around the Earth is tilted by about 5° with re­spect to the plane of Earth’s orbit around the Sun (the plane of the eclip­tic). Thus, when new and full moons occur, the Moon usu­ally lies to the north or south of a di­rect line through the Earth and Sun. Al­though an eclipse can only occur when the Moon is ei­ther new (solar) or full (lunar), it must also be po­si­tioned very near the in­ter­sec­tion of Earth’s or­bital plane about the Sun and the Moon’s or­bital plane about the Earth (that is, at one of its nodes). This hap­pens about twice per year, and so there are be­tween four and seven eclipses in a cal­en­dar year. Most of these eclipses are par­tial; total eclipses of the Moon or Sun are less fre­quent.
