Mark Your Calendar for May 2026’s Full Moons!

Written By: Catherine Boeckmann Executive Digital Editor and Master Gardener

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 12:56 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.

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!

Nice, but you're wrong about the proverbs quote. Proverbs never knew a fly fisherman.

Dude, my grandma, who was a woman of pure European blood in a very isolated rural area of Europe, called the whole month of may Flower Month. We usually make sculpture with certain flowers and leaves, and carpets of flowers in this month, so… the name is just logical.

Hello, I am a large beef farmer's daughter and now soon 52 yrs young. My parents were huge gardeners as well. I have had a vegetable/flower garden for as long as I can remember. I have never planted according to the moon phases. My parents spoke of always planting on the May Long Weekend. That is traditionally the time to plant in our zone 3. I am rethinking this tradition a little and tweaking it some... I am always struggling with spinach that bolts and lettuce! Well it loves cooler temps and I intend to plant it today or tomorrow along with peas, kale, brussell sprouts, and cabbage. The moon is in the waxing phase here now as just recently being the new moon. So it may just cost me some seed but after all that I have read I believe I will have a great harvest of these veg this year. PS my spinach actually over-wintered last year 2019-2020 which was not a very mild winter but lots of snow for insulation may have facilitated this. Poppies, snapdragons are going directly out soon as well. They have also year after year came up from self sowing and I am not worried about these hardy frost tolerant floweres. After the full moon in April I will experiment with the waning moon phase with potatoes, radish, turnip, beets, and onions. What do you think of this idea? I am wrong should I wait until the same periods in May as it is April here and our last frost date is June 6? Since the pandemic hit I started a mail order seed business. It is my new passion and so far growing and doing well and steady. Thanks for any advice you can offer.

Those root crops are all cool-weather tolerant, so you could certainly get away with starting them at the end of April and into early May. However, the most important factor is your garden's soil temperature. If the soil temperature is below 10°C (50°F), most seeds won't germinate or will take a longer time to get started. 

In any case, you'll want to keep a close eye on the forecast and cover any young plants (especially potatoes) to protect their foliage from frosts.

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.
