Why the September Full Moon is called the Full Corn Moon

The September Full Moon’s name is inspired by nature and agriculture. This month’s full moon nickname ties back to when corn is usually harvested.

And also to note, in some years, the September full moon is known by another name, the Full Harvest Moon. It depends on if the September or October full moon occurs closer to the Fall Equinox.

Looking at about 10 years of full moons, the September full moon is actually called the Full Harvest Moon more often than it’s called the Full Corn Moon.

When is the next Full Corn Moon in?

The next Full Corn Moon will be in 2025 because in 2021 the September Full Moon will be closer to the Fall Equinox than the October Full Moon.
