There will be not one, but two, Full Moons in May! The first Moon, the Full Flower Moon, reaches its peak on Friday, May 1⁠⁠⁠⁠⁠⁠⁠, while the second Moon, the Blue Moon (which is also a Micromoon), peaks on Sunday, May 31.  Find out the meaning of the Flower Moon, the Full Moon of May. 

When to See the Full Moons in May 2026

May 1: The Flower Moon

May’s first Full Moon, the Flower Moon, reaches peak illumination at 1:23 P.M. (EDT) on Friday, May 1. How fitting to have the Flower Moon arrive on May Day!

May 31: The Blue Moon

In May, a second Full Moon, a Blue Moon, will make an appearance. The term Blue Moon is most commonly used when we have two Full Moons in a single month. On Sunday, May 31, the Full Moon will peak at  4:45 A.M. EDT.

Find a location with unobstructed views of the horizon, if possible. See what time the moon will be visible in your area with our Moonrise and Moonset Calculator. 

The Blue Micromoon

This month also brings a Micromoon. Curious about how it compares to a Supermoon? The Full Moon on May 31, 2026, occurs just before reaching apogee on June 1.

Apogee refers to the point when the Moon is farthest from Earth. When the Full Moon occurs near this point, it’s classified as a “Micromoon”—the opposite of a Supermoon, so it will appear slightly smaller and dimmer than usual.

Why does the Moon’s distance vary? The Moon orbits Earth in an elliptical path, with one side closer and the other farther. While this affects its size and brightness, the difference is too subtle to notice with the naked eye. What often makes the Moon appear larger is the “Moon illusion”—an optical effect that occurs when it’s near the horizon. Since this Micromoon will be high in the sky, it likely won’t appear as large or imposing as a Full Moon closer to the horizon.

Why Is It Called the Flower Moon?

The Full Moon names used by The Old Farmer’s Almanac come from many places, including Native American, Colonial American, and European sources. Traditionally, each Full Moon name was applied to the entire lunar month in which it occurred, not solely to the Full Moon.

The Flower Moon

May’s Flower Moon name should be no surprise; flowers spring forth across North America in abundance this month!

  • “Flower Moon” has been attributed to Algonquin peoples, as confirmed by Christina Ruddy of The Algonquin Way Cultural Centre in Pikwakanagan, Ontario.
  • May’s Moon was also called the “Month of Flowers” by Jonathan Carver in his 1798 publication, Travels Through the Interior Parts of North America: 1766, 1767, 1768 (pp. 250-252), as a likely Dakota name. Carver stayed with the Naudowessie (Dakota) over a period of time; his expedition covered the Great Lakes region, including the Wisconsin and Minnesota areas.
  • Henry David Thoreau sparked the Native American Moon names as well, referencing the Flower Moon and Carver when he wrote about Native Americans.

Alternative May Moon Names

May’s Moon names tend to speak to the arrival of spring and all that it entails! 

The Cree names Budding Moon and Leaf Budding Moon celebrate the awakening of local flora, which really begins to leaf out now in many areas. Similarly, Planting Moon (Dakota, Lakota) marks the time when seeds should be started for the farming season ahead. 

The activities of animals marked spring’s arrival, too, which is highlighted by the Cree names Egg Laying Moon and Frog Moon, as well as the Oglala term Moon of the Shedding Ponies. All three names indicate that warmer weather is on the way!

I have long thought that if I've lived past lives, I have stared at the same moon from different eyes, in places and times long forgotten. Such a comforting thought :) Love your articles, thank you!

Like Connie on May 29, 2018 - 10:19am, I have always loved looking at the moon. When I was a little girl I would lay on the grass and let the moon "pull me". I can barely explain it in any terms that make sense but I could/can feel a subtle, visceral (sensation) of pulling (what I thought at the time, pre-5 years old). I thinking about it now, I feel it interacts with my solar plexus chakra and even as I type, I feel it. (true story) For all of our wisdom and knowledge though, we have so much yet to learn about who we really are and how we fit into the grand design. <3 THANKS too, to you for forging this path - to help bridge the past with the present & future.

I too have always had an feeling that as a young person could not understand. Now I'm in my later years and get it. Could not put into words what I knew in my mind.l never spoke of it,looking ,studying, and feeling these pulls toward it.After all,I went to Catholic school and the nuns only spoke of it as something G d made,yet ,I stayed in wonder.

My grandmother was a true believer in attending to health matters according to the farmer's almanac. I will be having hip and knee surgery in the near future. When would be the best time to have it done for healing during the month of May and June. thank you.

In the summer when its hot, it's harder to heal. My dad had double knee surgery and it was hot that summer. His knees just took longer.

The Moon changes phases slowly, so it will appear to be full before and after its "peak fullness," which occurred on the 29th of May.

I have always loved looking at the moon.When I was a little girl riding in the car,I really believed that it followed me! I have shown each grandchild the moon (and stars).My 2 year old great granddaughter loves the moon. I will be watching the moon come up tonight.
