~5 min

The Full Moon occurring this September will be the Harvest Moon. However, the October Full Moon can also be referred to as the Harvest Moon sometimes. Did Native Americans run out of names for the Full Moons by the end of the year? Read on to figure it out.


When is the Full Moon in September 2024?

This month, the Full Moon will occur on September 18 at 02:34 GMT (September 17, 9:34 p.m. EST). At this time, our natural satellite will lie in the constellation Pisces.

What is a Harvest Moon?

The Harvest Moon is the Full Moon closest to the autumnal equinox, which occurs in September in the Northern Hemisphere and in March in the Southern Hemisphere. This year, the Full Moon on September 18 is the Harvest Moon.

Why is the Harvest Full Moon 2024 special?

Full Harvest Moon and autumn equinox: Harvest Moon name meaning

The Harvest Moon is not associated with a particular month, unlike the other Full Moon names. Instead, it is connected to the autumnal equinox: the Full Moon that is nearest to it takes on the name. In the Northern Hemisphere, the Harvest Moon usually occurs in September, but around every three-five years, it is in October. In the Southern Hemisphere, the Harvest Moon takes place either in March or April.

This year, the autumnal equinox in the Northern Hemisphere is on September 22 at 12:44 GMT – that’s why the Full Moon occurring on September 18 is the Harvest Moon. In the Southern Hemisphere, the autumnal equinox is on March 20, 2024, at 03:07 GMT. Therefore, the Full Moon on March 25, 2024, will be the Harvest Moon for that part of the world.

Harvest Moon color: orange Moon

As the Moon hangs low on the horizon, it takes on a golden, orange, or red hue. The reason is that the blue wavelengths get scattered by the atmosphere, leaving more of the red wavelengths, so the Moon gets a warm glow. Pass our quiz and learn more about the possible colors of the Moon!

The September Full Moon and the Mid-Autumn Festival

The September Full Moon is celebrated by many nations. For the Chinese people, the September Full Moon marks the mid-Autumn Festival, also known as the Mooncake Festival or Lantern Festival. It is the second most important festival after the Lunar New Year. On this day, people traditionally get together with their family and friends, eat mooncakes, light up paper lanterns, and gaze at the Moon. Similar September Full Moon traditions are found in many cultures around the world, including Japan, Korea, Vietnam, India, and Sri Lanka.

September Supermoon

The September Full Moon 2024 is listed in the table of Supermoons by former NASA astrophysicist Fred Espenak. It is also included in the list of Supermoons by Richard Nolle, the astrologer who coined the term "Supermoon". This means that this Full Moon will occur near the perigee and will appear slightly larger and brighter in the sky than regular Full Moons. Check our special article to learn why there are two tables of Supermoons, and how they differ.

Partial lunar eclipse in September 2024

On September 18, between 02:12 GMT and 03:15 GMT, the Moon will pass through the Earth’s umbral shadow, creating a partial lunar eclipse. The lunar disc will be 3.5% covered by this shadow, so it may look as if someone “took a bite” out of our Moon. The partial lunar eclipse will be visible from Europe, much of Asia, Africa, North America, South America, the Arctic, and Antarctica.

“Corn Moon” and other September Full Moon names

As we mentioned before, the Harvest Moon is the name used to denote both September and October Full Moons, depending on the date of the autumnal equinox. When the Harvest Moon occurs in October, the September Full Moon is called the Corn Moon. The other traditional name used by the Native American tribes is the Rutting Moon: during this period, the mating season begins for deer.

The other alternative names for the September Full Moon include:

  • Chinese: Chrysanthemum Moon
  • Celtic: Singing Moon
  • Wiccan: Barley Moon
  • Cherokee: Nut Moon
  • Southern Hemisphere: Worm Moon, Lenten Moon, Crow Moon, Sugar Moon, Chaste Moon, Sap Moon
