Can you tell me the full moon names?

The full moons have names corresponding to the calendar months or the seasons of the year.

Some almanacs like to give each month a special full moon name. Other almanacs like to reference full moons relative to seasonal markers, as defined by equinoxes and solstices. Is one way better than the other? No. Both have their roots in folklore.

Here we list common North American full moon names – first by month – and then by season.

Full moon names by month:

January: Old Moon, or Moon After Yule
February: Snow Moon, Hunger Moon, or Wolf Moon
March: Sap Moon, Crow Moon, or Lenten Moon
April: Grass Moon, or Egg Moon
May: Planting Moon, or Milk Moon
June: Rose Moon, Flower Moon, or Strawberry Moon
July: Thunder Moon, or Hay Moon
August: Green Corn Moon, or Grain Moon
September: Fruit Moon, or Harvest Moon
October: Harvest Moon, or Hunter’s Moon
November: Hunter’s Moon, Frosty Moon, or Beaver Moon
December: Moon Before Yule, or Long Night Moon

About once every 19 years, February has no full moon at all. Moreover, in 7 out of every 19 years, two full moons will fall in the same calendar month. The second of the month’s two full moons is popularly referred to as a Blue Moon. The next Blue Moon by this definition will happen on August 31, 2012.

Full moon names by season:

After the December solstice:
Old Moon, or Moon After Yule
Snow Moon, Hunger Moon, or Wolf Moon
Sap Moon, Crow Moon or Lenten Moon

After the March equinox:
Grass Moon, or Egg Moon
Planting Moon, or Milk Moon
Rose Moon, Flower Moon, or Strawberry Moon

After the June solstice:
Thunder Moon, or Hay Moon
Green Corn Moon, or Grain Moon
Fruit Moon, or Harvest Moon

After the September equinox:
Harvest Moon, or Hunter’s Moon
Hunter’s Moon, Frosty Moon, or Beaver Moon
Moon Before Yule, or Long Night Moon

There are usually three full moons in between an equinox and a solstice, or vice versa. Seven times in 19 years, four full moons fall in a single season. In that case, the third of a season’s four full moons is also called a Blue Moon. The next Blue Moon by this definition will happen on August 21, 2013.

When is the next Blue Moon?

  4. Gene says:

    Hmmm…I guess it depends on where you get your information from because many of these moon names are in different cultures and are named for different reasons. Check out Native American moon names and Celtic names. They all differ. Nice though.

  5. Victor says:

    Some definitions of a blue moon differ than the one here. Other sources claim it is the third full moon of a 3-month season that has 4 full moons.

    Is there a name for February without a full moon?

  13. Lesley says:

    Interesting names for the full moon but they are northen hemispher specific and probably mostly Europe and North America specific. The Long Night Moon in December would be a Short Night Moon in Australia. Are there other names for the full moon in other countries, Japan or China or Korea for example, and What about in South American countries?

    • Deborah Byrd says:

      Lesley, you’re right. We’re in North America, and many of these moons names stem from North American – or at least Northern Hemisphere – traditions.

      We’d love to get a good source of moon names from the Southern Hemisphere. If anyone knows of a credible source of info, please let us know.
