Full moon calendar: dates and times for every full moon this year
The full moon has been a source of fascination, from precipitating werewolf transformations to controlling the tides. Across the globe, it has been an important part of cultural and spiritual practices as well as scientific phenomena. The full moon, the period when the moon is at its largest and brightest, is merely one part of the lunar cycle, which is approximately one month in length. While it can be seen globally, the time of viewing varies from time zone to time zone.
The next full moon is at 12:56 pm EST on Monday, May 12 and is known as the Flower Moon.
Here is a look at all the full moons during 2025, interesting facts, as well as when to see them.
Lunar cycle
The moon is not capable of producing its own light, so what we see from Earth is a reflection of the sun's light shining on the moon. Still, the moon is orbiting around the Earth while the Earth is orbiting around the sun, which affects how much light shines on the moon. As the moon goes around the Earth, "different parts of it are illuminated by the sun," said The Planetary Society. "But because the same side of the Moon always points toward Earth, most of the time some of the illuminated part (daytime on the Moon) faces away from us. And, some of the non-illuminated part (nighttime on the Moon) faces toward us."
How we see the moon from Earth can be tracked with the lunar cycle, which is approximately 29.5 days. During that time, the moon goes through eight phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. Essentially, the moon is not visible in its new moon phase and gains more visibility until it becomes a full moon and then reduces in visibility once more. The full moon is "as close as we come to seeing the sun's illumination of the entire day side of the moon, said NASA. The moon appears full for approximately two days before beginning to wane.
Some full moons are more special than others. Of the 12 full moons that occur in a year, three or four of them may be supermoons, which is when the full moon "occurs at the closest point to Earth during its orbit, it appears larger and brighter," said the Natural History Museum. In another visual spectacle, sometimes the full moon can have a lunar halo, which is an "optical illusion" that causes a large bright ring to surround it, said Space.com (a sister site of The Week). "This striking and often beautiful halo around the moon is caused by the refraction of moonlight from ice crystals in the upper atmosphere." The halos are not uncommon and can occur at any time of year; they are most common in the winter months. They are also most visible when a full moon is surrounded by thin cirrus clouds.
