May's full moon — named for the abundance of spring flowers. The lore behind the name, what it looks like, and how to see it.
By May, spring is in full force and flowers bloom everywhere across the temperate Northern Hemisphere — hence the Flower Moon, a name used by Algonquin peoples. Agricultural communities also called it the Corn Planting Moon and, in Europe, the Milk Moon or Hare Moon, for the season of new growth and grazing.
The May full moon rides at a moderate height — past the high winter moons, heading toward the low summer ones. It looks bright and clear, and is the last full moon before the lowest moons of the year around the summer solstice.
May 2026 is the rare month that gets two full moons: the Flower Moon on May 1 and a second full moon on May 31 — a Blue Moon, the origin of the phrase "once in a blue moon." Because a lunar cycle runs about 29.5 days, a full moon on the 1st or 2nd of a long month leaves just enough room for a second before the month ends. It happens roughly every two and a half years, and 2026 spends its turn on May. The Flower Moon opens the month; the Blue Moon closes it.
Fullness comes at 17:23 UTC on May 1 — early afternoon in the Americas — so the nights of April 30 and May 1 are equally good on that side of the Atlantic, while Europe's best night is May 1 outright.
May's full moon is not just an almanac entry — it is Vesak, the most sacred date of the Buddhist calendar, marking the birth, enlightenment and passing of the Buddha, observed by hundreds of millions across Asia on this exact full moon. Europe's agrarian names for the same moon are humbler: the Milk Moon, for cattle back on rich spring pasture, and the Hare Moon, for the animal of spring fertility folklore. The Algonquian Corn Planting Moon records the same signal — soil finally warm enough to sow.
