Each month's full moon has traditional names in many cultures.

Almanacs and news stories give every full moon a name. Most of the names used in English today were popularised by the Maine Farmers’ Almanac in the 1930s and draw on a mix of Native American, colonial American and European traditions. They are seasonal labels, not astronomical terms, and different peoples used different names for the same moon.

The common names

Month Name Usual explanation
January Wolf Moon wolves heard howling in midwinter
February Snow Moon the snowiest month in much of North America
March Worm Moon earthworms returning as the ground thaws
April Pink Moon early spring wild phlox (moss pink)
May Flower Moon spring flowers in bloom
June Strawberry Moon the strawberry harvest
July Buck Moon new antlers on male deer
August Sturgeon Moon sturgeon in the Great Lakes
September Harvest Moon* light for gathering crops
October Hunter’s Moon* hunting after the harvest
November Beaver Moon setting traps before the freeze
December Cold Moon the long cold nights

* The Harvest Moon is the full moon nearest the September equinox, so it occasionally falls in early October; the Hunter’s Moon is the one after it.

The next full moons

Calculated as the instant the moon is opposite the sun, in UTC:

Near and far moons in the coming year

The moon’s distance at full moon varies by tens of thousands of kilometres, and the next twelve months show the whole range. Calculated distances between the centres of the Earth and the moon at each full moon:

The December full moon will look about 14% wider than the July one. Side by side in photographs the difference is clear; in the sky, months apart, almost nobody notices.

Names in other traditions

The English almanac names are only one set. Many cultures name or celebrate full moons in their own calendars:

Because these calendars are lunar or lunisolar, their full moon festivals move against the Gregorian calendar from year to year, while the astronomical moment of full moon is the same for everyone.

Blue moons and supermoons

Two other names come up often. A blue moon has two definitions: the second full moon in a calendar month, or the third full moon in a season that has four. Neither has anything to do with colour. A supermoon is a full moon near perigee, the closest point of the moon’s orbit, when it appears up to about 14% larger and noticeably brighter than at its farthest.

How many full moons in a year

A calendar year usually has twelve full moons, but the lunar cycle, about 29.5 days, is shorter than the average month, so about every two and a half to three years one month gets two. The second is the calendar “blue moon”. The months from October 2026 to the end of 2027 contain fifteen full moons in all, from the Hunter’s Moon of 26 October 2026 to the full moon of 13 December 2027, without any month holding two.

Because the full moon is a single instant, the month it falls in can depend on your time zone: a full moon in the last hours of a month in UTC may fall on the first day of the next month in Asia. Blue moons are therefore not always shared worldwide.

Names on a certificate

Resthe certificates record the date, the place and the exact moment of full moon, and the moon’s illuminated fraction. They do not assign a traditional name, because names vary by culture and some months have several. If the Cold Moon or the Harvest Moon matters to you, put it in your message.

The full moon night chosen for a gift is the local night, sunset to sunrise at your point, whose middle is closest to the moment of full moon. You can see which night that is for any place with The Full Moon Night.
