Full moon names...

Post by merle »

not to dredge up this old can ol' worms, but...

The "Earth Sky News" does a great job explaining the Full Moon names:


The moon names and when a Blue moon is are in relation to the season and not the month. The "2019 SUPER BLOOD WOLF MOON" from Mark's forum post. The Wolf moon is correct based on it being the second full moon after the winter solstice (the first was December 22nd). But this full moon is also called Snow Moon and / or Hunger Moon.

The article also explains the original definition of the Blue Moon being the third full moon of a season, which we have this February. This is the original definition from the Farmer's Almanac that was misconstrued by a Sky & Telescope article which led to the "popular" definition of two full moons in a month.


Full moon names by season (Northern or Southern Hemisphere):
After the winter solstice:
Old Moon, or Moon After Yule
Snow Moon, Hunger Moon, or Wolf Moon
Sap Moon, Crow Moon or Lenten Moon

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

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

After the autumnal 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 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 last Blue Moon by this definition happened on May 21, 2016 and the next will be on May 18, 2019. (According to the S & T article, the Blue moon is February 19, 2019, not May.)


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

About once every 19 years, February has no full moon at all.
