Why Is It Called the Buck Moon?

The full Moon names used by The Old Farmer’s Almanac come from a number of places, including Native American, Colonial American, and European sources. Traditionally, each full Moon name was applied to the entire lunar month in which it occurred, not solely to the full Moon.

The Buck Moon

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. Bucks shed and regrow their antlers each year, producing a larger and more impressive set as the years go by.

Alternative July Moon Names

Several other names for this month’s Moon also reference animals, including Feather Moulting Moon (Cree) and Salmon Moon, a Tlingit term indicating when fish returned to the area and were ready to be harvested.

Plants are also featured prominently in July’s Moon names. Some of our favorites are Berry Moon (Anishinaabe), Moon When the Chokecherries are Ripe (Dakota), Month of the Ripe Corn Moon (Cherokee), and Raspberry Moon (Algonquin, Ojibwe).

Thunder Moon (Western Abenaki) and Halfway Summer Moon (Anishinaabe) are alternative variants that refer to the stormy weather and summer season.

Moon Facts

  • On July 20, 1969, Neil Armstrong became the first person to step foot on the Moon. He also placed the U.S. flag there.
  • On July 31, 1999, the ashes of astrogeologist Eugene Shoemaker were deposited on the Moon.

We leave you with a poem by James N. Matthews (1852–1910):

A moon-flooded prairie; a straying 
Of leal-hearted lovers; a baying 
Of far away watching dogs; a dreaming 
Of brown-fisted farmers; a gleaming 
Of fireflies eddying nigh, —
And that is July!
