September’s Full Moon: A “Micromoon” Harvest Moon on Friday the 13th!
This month’s full Moon rises on the night of Friday, September 13, and reaches peak fullness at 12:33 a.m. EDT on the 14th.
Yes, that’s right—the brilliant Harvest Moon makes its annual appearance on Friday the 13th this year! What a clash of lore! Look skyward on Friday night for the best view of the shining Full Harvest Moon (but watch out for black cats and open ladders, too).
How Rare is a Full Moon on Friday the 13th?
Because Friday the 13th only happens between one and three times a year, it’s not particularly common for the full Moon to line up with it exactly. The last time there was a full Moon on Friday the 13th was in January 2006—13 years ago—and the next won’t occur until August 2049. Needless to say, cherish it this year!
What is a Micromoon?
As if this Harvest Moon wasn’t interesting enough already, September’s full Moon will also be a “micromoon.”
By this time, you’ve probably heard of a supermoon. A micromoon is exactly the opposite: a full Moon that occurs when the Moon is at the farthest point in its orbit around Earth (the point of apogee). In other words, the Moon is about as far from Earth as it can get, causing it to appear about 7% smaller and 15% dimmer than usual.

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 not tied to the month of September. Instead, it depends on an astronomical event: the autumnal equinox. The full Moon that happens nearest to the equinox (September 22 or 23) takes on the name “Harvest Moon,” rather than its traditional name, which means that a Harvest Moon may occur in either September or October.
The Harvest Moon provides the most light at the time of year when it was traditionally needed most: during the harvest!
Other September Full Moon Names
Historically, Native Americans gave a name to each month’s full Moon, naming it in relation to a natural event or sign of the season. This aided them in tracking the progression of the year
One such name for the September full Moon was the Full Corn Moon because it traditionally corresponded 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 for this month include:
- “Moon When the Plums Are Scarlet” by the Lakota Sioux.
- “Moon When the Deer Paw the Earth” by the Omaha.
- “Moon When the Calves Grow Hair” by the Sioux.
One of September’s traditional full Moon names, the Full Corn Moon.

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.
