May 2026 will be a special month for skywatchers, as the sky will host two full moons.
The first, known as the Flower Moon, will peak on Friday, May 1 at 8:23 PM (Greece time), offering ideal viewing conditions shortly after sunset.
The second, on May 31, is what’s known as a Blue Moon, a phenomenon that occurs when two full moons fall within the same calendar month.
“Flower Moon”: Where Does the Name Come From?
The name “Flower Moon” isn’t random. It originates from the traditions of indigenous peoples of North America, who gave names to full moons based on the natural phenomena of each season. May, as the month of nature’s full bloom, became associated with the abundance of flowers, hence the name. Similarly, in other traditions the same full moon is called the “Milk Moon” or the “Corn Planting Moon,” reflecting the agricultural activities of the time.
Astronomically, a full moon occurs when the Earth is positioned between the Sun and the Moon, causing the Moon’s entire illuminated side to be visible from Earth. In the case of May 1, the event coincides with the spring season in the Northern Hemisphere, reinforcing its symbolism of renewal and life.
Although the exact moment of the full moon falls in the evening, the moon will appear full and bright on the nights both before and after the peak, giving everyone the opportunity to observe it with the naked eye — even from urban areas.
