September Full Moon Names
The Harvest Moon
This year, the September full Moon is called the Harvest Moon. Unlike other full Moon names, which are specific to their respective months, the Harvest Moon is tied to an astronomical event: the autumnal equinox. The full Moon that falls nearest to the equinox (September 22) takes on the name “Harvest Moon,” rather than its traditional name. (This means that a Harvest Moon could occur in either September or October.)
The Harvest Moon provides the most light at the time when it’s needed most—to complete the harvest!
Other Full Moon Names
Historically, the Native Americans who lived in the area that is now the northern and eastern United States (where early Colonists lived) kept track of the seasons by giving a distinct name to each reoccurring full Moon. This name was applied to the entire month in which it occurred. These names, and some variations, were Algonquin tribes from New England to Lake Superior.
The common September Moon name was the Full Corn Moon because it traditionally corresponds with the time of harvesting corn. It was also called the Barley Moon, as this is the time to harvest and thresh ripened barley.
Other Full Moon names include:
- “Moon When the Plums Are Scarlet” by the Lakota Sioux Native Americans.
- “Moon When the Deer Paw the Earth” by the Omaha Native Americans.
- “Moon When the Calves Grow Hair” by the Sioux Native Americans

Moon Facts & Folklore
- Usually the Moon rises about 50 minutes later each day, but around the time of the autumnal equinox, it rises only around 30 minutes later in the United States—even less in Canada.
- Frost occurring in the dark of the moon kills fruit buds and blossoms, but frost in the light of the moon will not.
