The full buck moon will reach its peak illumination on Thursday, July 10. It’s just one of this month’s celestial highlights.

The Old Farmer's Almanac, which began publishing full moon names in the 1930s, says some Native American tribes called July's full moon the "buck moon" because it occurs in early summer, when male deer (bucks) typically begin growing new antlers covered in velvety fur.

On July 10, 2025, the Buck Moon or Purnima, a powerful time for spiritual practices, will occur with the Moon in Sagittarius. This Full Moon encourages transformation and new beginnings, mirroring the growth of deer antlers.
