Historically, names for the full or new Moons were used to track the seasons. Think of them as “nicknames” for the Moon! See Moon names for each month of the year and their meanings.
Where Do Moon Names Come From?
The Moon names we use in The Old Farmer’s Almanac come from Native American, Colonial American, or other traditional North American sources passed down through generations.
Note that for Native American names, each Moon name was traditionally applied to the entire lunar month in which it occurred, the month starting either with the new Moon or full Moon. Additionally, a name for the lunar month might vary each year or between bands or other groups within the same nation.
Some names listed here may reflect usage at one time in history, but may no longer be used by a designated group today. Many of the names listed here are English interpretations of the words used in Native American languages. They are only roughly aligned here with the months of the Gregorian calendar; you’ll notice that some names are repeated in multiple months.

|January||Full Wolf Moon||The howling of wolves was often heard at this time of year. It was traditionally thought that wolves howled due to hunger, but we now know that wolves use howls to define territory, locate pack members, reinforce social bonds, and gather for hunting.||
• Canada Goose Moon
|February||Full Snow Moon||February is typically a time of heavy snowfall.||
• Bald Eagle Moon
|March||Full Worm Moon||Traditionally thought to be named after the earthworms of warming spring soil. Alternatively, in the late 1700s, Jonathan Carver wrote that this Moon actually refers to a different sort of “worm”—larvae—which emerge from the bark of trees and other winter hideouts around this time.||
• Crow Comes Back Moon
|April||Full Pink Moon||This full Moon heralded the appearance of the “moss pink,” or wild ground phlox—one of the first spring wildflowers.||
• Breaking Ice Moon
|May||Full Flower Moon||Flowers spring forth in abundance this month.||
• Budding Moon
|June||Full Strawberry Moon||This was the time to gather ripening strawberries in what is now the northeastern United States.||
• Berries Ripen Moon
|July||Full Buck Moon||At this time, a buck’s (male deer’s) antlers are in full growth mode.||
• Berry Moon
|August||Full Sturgeon Moon||The sturgeon of the Great Lakes and Lake Champlain were said to be most readily caught during this full Moon.||
• Black Cherries Moon
|September||Full Corn Moon (or Harvest Moon*)||This full Moon corresponds with the time of harvesting corn. (See note below regarding the “Harvest Moon.”)||
• Autumn Moon
|October||Full Hunter’s Moon (or Harvest Moon*)||This is the month when the game is fattened up for winter. Now is the time for hunting and laying in a store of provisions for the long months ahead.||
• Drying Rice Moon
|November||Full Beaver Moon||This was the time when beavers finished preparations for winter and retreated into their lodges.||
• Deer Rutting Moon
|December||Full Cold Moon||This is the month when the winter cold fastens its grip and the nights become long and dark.||
• Drift Clearing Moon
|*According to one tradition, which the Old Farmer’s Almanac honors, the Harvest Moon is always the full Moon that occurs closest to the September equinox. Most years, it falls in September; every three years, it falls in October. (Astronomical seasons do not match up with the lunar month.) If the Harvest Moon occurs in October, the September full Moon is usually called the Corn Moon instead. Similarly, the Hunter’s Moon always follows the Harvest Moon. (Note that these last two conditions are not according to Native American tradition.)|
Why Native Americans Named the Moons
The early Native Americans did not record time by using the months of the Julian or Gregorian calendar. Many tribes kept track of time by observing the seasons and lunar months, although there was much variability. For some tribes, the year contained 4 seasons and started at a certain season, such as spring or fall. Others counted 5 seasons to a year. Some tribes defined a year as 12 Moons, while others assigned it 13. Certain tribes that used the lunar calendar added an extra Moon every few years, to keep it in sync with the seasons.
Each tribe that did name the full or new Moons (and/or lunar months) had its own naming preferences. Some would use 12 names for the year while others might use 5, 6, or 7; also, certain names might change the next year. A Moon name used by one tribe might differ from one used by another tribe for the same time period, or be the same name but represent a different time period. The name itself was often a description relating to a particular activity/event that usually occurred during that time in their location.
Colonial Americans adopted some of the Native American Moon names and applied them to their own calendar system (primarily Julian, and later, Gregorian); they also brought their own traditions from Europe. Since the Gregorian calendar is the system that many in North America use today, that is how we have presented the list of Moon names, as a frame of reference.

Other Full Moon Names
The following Moon names came into popular use more recently and do not refer to any specific month’s Moon:
- Blue Moon: Occasionally, two full Moons occur within the same calendar month. The first full Moon goes by the name normally assigned to that month’s full Moon, but the second full Moon is commonly called a Blue Moon. Blue Moons occur about every 2½ years.
- Black Moon: In contrast to the Blue Moon, Black Moon has been used to refer to a month in which there is no full Moon; this can only occur in February, because the calendar month has fewer days (28 or 29 days) than the lunar month (about 29.5 days). The term may also refer to a second new Moon occurring within a calendar month; by this definition, a Black Moon can never occur in February.
- Supermoon: A full Moon is said to be a “Supermoon” when it is at the point in its orbit closest to Earth. In astronomy, the terms “perigee syzygy” or “perigee full Moon” are typically used instead of “Supermoon.” Learn more about Supermoons.
