The Full Flower Moon
Why is it called the Full Flower Moon? This tradition of naming Moons is rich in history.
We use full Moon names that were used during Native American and Colonial times to help track the seasons—usually from the Algonquin tribes who lived in the same areas as the Colonists.
Depending on the community, May’s full Moon was called the Full Flower Moon as well as Mother’s Moon, Milk Moon, and Corn Planting Moon. The May full Moon marked a time of increasing fertility, with temperatures warm enough for safely bearing young, a near end to late frosts, and plants in bloom.
Here at The Old Farmer’s Almanac, we have long honored the Native American Moon names and the folklore of those who came before us.

A Blue Flower Moon?
Although a Blue Moon is commonly defined as the “second full Moon to occur within a single calendar month,” this is not the traditional meaning of the term. Originally, a Blue Moon was the third of four full Moons to occur within one astronomical season.
According to this definition, May’s Full Flower Moon is a Blue Moon this year! This is thanks to the timing of the March full Moon, which occurred on the same day as the Spring Equinox, and the upcoming June full Moon, which occurs just a few days prior to the Summer Solstice, making the May full Moon the third full Moon in the season of spring.
The four full Moons this spring are:
- Full Worm Moon: March 20 at 9:43 P.M. EDT
- Full Pink Moon: April 19 7:12 A.M. EDT
- Full Flower Moon: May 18 at 5:11 P.M. EDT <-– Blue Moon
- Full Strawberry Moon: June 17 at 4:31 A.M. EDT
