What is a “Harvest Moon”?
The Full Moon Closest to the Autumnal Equinox
Every full moon has a special name: the Wolf Moon, the Worm Moon, the Sprouting Grass Moon, the Thunder Moon and yes, the Harvest Moon just to name a few. The Harvest Moon is the full Moon that falls closest to the Autumnal equinox. The name was given to the Moon by farmers because they could still harvest from the light of the Harvest Moon. For several nights in a row, the Moon rises at sunset, which gives it the illusion of being larger and more orange in color. It’s the great pumpkin, Charlie Brown! Source: Space.com
