The seventh full moon of 2024—the “Buck Moon”—will grace the early evening skies this coming week as it rises in the east just as the sun sets in the west. Named the “Buck Moon”—but also known as the “Thunder Moon” and the “Hay Moon”—here’s everything you need to know about it, including exactly when, where and how to see it at its best from where you are:
When Is The ‘Buck Moon?’ The “Buck Moon” will turn full at 10:17 UTC/6:17 a.m. EDT on Sunday, July 21, but from North America, the best time to watch it rise will be at moonrise the previous evening.
The full moon will look its biggest and best as it appears on the eastern horizon during dusk. For about 15-20 minutes, it will appear orange. That’s because you’re looking at it through the densest part of Earth’s atmosphere.
Long-wavelength red and orange light travels more easily through the atmosphere than short-wavelength blue light, which strikes more particles and gets scattered. The same physics (Raleigh scattering) explains why a sunset looks orange.
"The full Moon in July is called the Buck Moon because the antlers of male deer (bucks) are in full-growth mode at this time," as The Old Farmer's Almanac says. "Bucks shed and regrow their antlers each year, producing a larger and more impressive set as the years go by."
The name "Buck Moon" arises from a traditional name from the Algonquin tribes, according to a NASA July 2021 moon guide, in what is now the northeastern United States, eastern Ontario and southern Quebec. That said, the moon may not be called the same name by all Algonquin peoples or by all Indigenous cultures; for example, another name attributed to the Algonquin for the July moon is the Thunder Moon. Rao names a few other Indigenous July moon names in his column.
Europeans (traditional) called this the Hay Moon due to the haymaking season, and sometimes the Mead Moon. Hindus, Buddhists, and Jains may call July's moon the Guru Full Moon (Guru Purnima), "celebrated as a time for clearing the mind and honoring the guru or spiritual master," NASA said.
Theravada Buddhists may call July's moon the Asalha Puha (also known as Dharma Day or Esala Poya – a festival celebrating Buddha's first sermon, NASA said). July's moon also marks the beginning of a three-month annual Buddhist retreat called Vassa.
July's full moon has also been called the Full Thunder Moon and the Full Hay Moon, as July is considered to be the season with the most frequent thunderstorms and the time of year when farmers harvest, bale and stow hay for the upcoming winter.
