Every full moon has a name. Most English speakers know a handful: Harvest Moon, Hunter's Moon, maybe Strawberry Moon from a recent headline. But the full naming tradition runs much deeper. Different peoples gave different names to the same moons, and the names they chose reveal what mattered most to them in each season: what was growing, what was dying, what was migrating and what needed doing before the weather turned.
The names most commonly used in English today come primarily from Algonquin-speaking peoples of northeastern North America, filtered through colonial almanacs. But parallel naming traditions exist across Celtic, Anglo-Saxon, medieval European and East Asian cultures. The same full moon seen from Massachusetts and from Shropshire received completely different names because the people naming it lived in completely different relationships with their land.
January: Wolf Moon
The most widely agreed-upon name. Wolves were vocal during January's deep cold, and their howling through frozen nights made an indelible impression on anyone living close to the land. The Algonquin name referenced the same observation. Anglo-Saxon tradition called this the "Moon After Yule," tying it to the festive calendar rather than the natural world. The Celtic name was "Quiet Moon" or "Stay Home Moon," reflecting the practical reality that January was not a time for travel or outdoor work.
In Chinese tradition, the first full moon of the year (which falls between late January and late February depending on the lunisolar calendar) is the Lantern Festival moon, celebrated with illuminated displays and tangyuan rice balls.
February: Snow Moon
February typically brings the heaviest snowfall in northeastern North America. The Algonquin name reflects this directly. Some tribes called it the Hunger Moon or Bone Moon, referencing the scarcity of food at the deepest point of winter when stored provisions ran low and fresh game was scarce. The Cherokee called it the Bony Moon for the same reason: animals were thin and people thinner.
Anglo-Saxon tradition called this the Storm Moon. In Scotland, it was the "Wild Moon." Both names capture the same reality from different angles: February is harsh, and naming the moon after harshness was an act of recognition rather than complaint.
March: Worm Moon
As the ground softens, earthworms begin appearing in thawed soil. Their castings (small mounds of digested earth) are among the earliest visible signs that winter's grip is loosening. The Algonquin name captures this humble but reliable signal. Some sources suggest the "worm" originally referred to beetle larvae emerging from thawing tree bark rather than earthworms, but the principle is the same: life stirring underground.
Alternative names include Crow Moon (the return of crows signalling the end of winter), Crust Moon (the snow surface crusts over from daily thawing and nightly refreezing) and Sap Moon (maple sap begins flowing). The Pueblo peoples called it the Moon When the Leaves Break Forth. Each name tracks a different biological indicator of spring's approach.
April: Pink Moon
Named not for the colour of the moon but for the colour of the ground. Phlox subulata, one of the earliest wildflowers to bloom across eastern North America, carpets hillsides in pink during April. The moon takes its name from the flowers below it. This surprises many people who assume the moon itself appears pink, which it does not (though atmospheric conditions can occasionally tint any moon reddish).
The Lakota called this the Moon When the Streams Are Again Navigable. The Celtic name was Seed Moon or Growing Moon. The Dakota called it the Moon When the Geese Return. April's names across cultures consistently reference movement and return: water flowing, birds arriving, flowers emerging. The frozen stillness of winter is definitively over.
May: Flower Moon
Flowers are no longer scattered pioneers. In May, they are everywhere. Wildflower season peaks across the northern hemisphere and the name requires no interpretation. The Cree called it Budding Moon. The Ojibwe called it Planting Moon, shifting focus from what nature is doing to what humans should be doing in response.
In medieval England, this was the Milk Moon, reflecting the season when cows (now grazing on fresh spring grass) produced the richest milk. The pastoral economy made this the most important dietary fact of the month, more relevant to daily life than which flowers were blooming.
June: Strawberry Moon
Wild strawberries ripen in June across northeastern North America. The Algonquin, Ojibwe and Haida peoples all used names referencing this harvest. In Europe, where wild strawberries also ripen in June, the name Rose Moon was more common. The Anglo-Saxon name was the Mead Moon, referencing the fermented honey drink that was traditionally brewed in early summer.
June's full moon has the distinction of being the one closest to the summer solstice. In the Northern Hemisphere, it sits lowest in the sky of any full moon, spending more time near the horizon. This means it spends more of its visible hours being filtered through thick atmosphere, often appearing amber or golden. The atmospheric reddening that makes any horizon moon look warm is especially pronounced for June's low-sitting full moon.
July: Buck Moon
Male deer (bucks) grow new antlers beginning in July. The velvet-covered antlers are visually distinctive and seasonally precise, making them a natural marker. The Tlingit called this the Salmon Moon, tracking a completely different animal whose seasonal behaviour was far more relevant to their coastal existence. The Comanche called it the Hot Moon, requiring no explanation.
The Anglo-Saxon name was the Hay Moon, reflecting the central agricultural activity of July: cutting and drying hay for winter fodder. The thunder moon is another common alternative, referencing the peak of summer thunderstorm season.
August: Sturgeon Moon
Large sturgeon were most readily caught in the Great Lakes and Lake Champlain during August. The name comes from fishing peoples whose annual cycle revolved around the availability of specific species at specific times. The Assiniboine called it the Black Cherries Moon. The Cree called it the Flying Up Moon, referencing young birds taking first flight.
This is the least commonly recognised of the twelve names in modern usage. Many people have never heard of the Sturgeon Moon, which may reflect the decline of the sturgeon itself. When the fish were abundant enough to define a month, their name belonged to the moon. Now that they are endangered in most of their historic range, the name has faded with them.
September: Harvest Moon
The most famous name and the only one with an astronomical rather than purely cultural definition. The Harvest Moon is the full moon closest to the autumn equinox, which means it sometimes falls in October rather than September. What makes it special is its behaviour: near the equinox, the daily delay in moonrise shrinks to as little as 25 minutes (versus the usual 50), providing several consecutive evenings of early moonrise and extended working light for farmers bringing in the harvest.
This is not folklore. It is orbital mechanics. The shallow angle of the ecliptic relative to the horizon near the equinox produces a measurable and predictable reduction in the moonrise delay. Farmers did not need to understand the geometry to notice the effect: several nights in a row, bright moonlight arrived just as the sun set, giving extra hours to work the fields.
October: Hunter's Moon
The full moon following the Harvest Moon. Fields have been cleared, crops brought in and animals are visible against the stubble. Hunting conditions are optimal: clear sight lines, fattened prey preparing for winter and the same favourable moonrise timing that characterised the Harvest Moon (though slightly diminished). The name appears across both Native American and European traditions.
The Ojibwe called this the Falling Leaves Moon. The Anglo-Saxon name was the Blood Moon, referencing not a lunar eclipse but the autumn slaughter of livestock, when animals that could not be fed through winter were killed and their meat preserved. The name is practical, not dramatic.
November: Beaver Moon
Two explanations persist. Either beavers are most active in November building their winter lodges and dams, making them easier to trap, or this is when trappers set beaver traps to ensure a supply of warm fur for winter. Both may be true simultaneously. The fur trade made beaver pelts the most valuable commodity in northeastern North America for two centuries, giving the animals outsized cultural significance.
The Cree called this the Frost Moon. The Lakota called it the Moon When Horns Are Broken Off, referencing deer shedding antlers after the rutting season. In medieval Europe, this was the Mourning Moon, acknowledging the rapid shortening of days and the approaching solstice darkness.
December: Cold Moon
The simplest and most universal name. December nights are the longest and coldest. The full moon rides highest in the sky of any month (because it is opposite the low-sitting December sun), providing the maximum number of hours of moonlight at the time of year when light is most scarce and most valued.
The Mohawk called this the Cold Moon. The Cherokee called it the Snow Moon (distinct from February's Snow Moon in other traditions). In Anglo-Saxon England, it was the Moon Before Yule. In one sense, December's moon is where the cycle began long before anyone standardised names: the longest night, the brightest moon, the turning point of the year.
Why the Names Disagree
There was never a single authority. The Algonquin peoples of the northeast used different names from the Lakota of the plains, who used different names from the Tlingit of the Pacific coast, who used different names from the Anglo-Saxons across the ocean. Each community named the moon after what was happening in their specific landscape during that month. The salmon that defined July for coastal peoples did not exist in the Great Lakes. The maple sap that marked March in New England did not flow in the Scottish Highlands.
What the names share is the principle: the moon's cycle was a calendar, and each month's full moon was a bookmark in the year's story. The names were not decoration. They were information, compressed into a word or phrase and passed down precisely because they told you something you needed to know about the world you lived in.
