On September 22, 2022, at 9:04 PM EDT in the Northern Hemisphere, the fall equinox occurs. The equinox happens simultaneously everywhere. The astronomical event known as the autumnal equinox signals the beginning of autumn (or “fall”). The autumnal equinox takes place in September in the time of Northern Hemisphere and also in March in the Southern.

An Happy Equinox is what?

The Sun passes what we refer to as the “celestial equator” at an equinox, which is really a hypothetical extrapolation of the Earth’s equator line. The Sun’s center precisely crosses this line during the equinox. For people in the Northern Hemisphere, the autumnal equinox occurs when the Sun passes the equator moving from north to south; the vernal equinox occurs when it passes from south to north. The opposite is true in the Southern Hemisphere.

Days get shorter than nights after the vernal equinox as the Sun keeps rising later as well as nightfall comes earlier. The winter solstice marks the conclusion of this and the beginning of a new day lengthening. The Latin roots of “equinox” are aequus, which means “equal,” and nox, which means “night.” The length of both the day & night is about equal on the equinox.

The Equinox and the Harvest Moon

One of our fascinating tidbits about the fall equinox is how it interacts with the supermoon. It’s odd that the full Moon closest to the vernal equinox is typically referred to as the “Harvest Moon.” How come?

Surprise, surprise: farming is involved! The full Moon rises before sunset on several nights in a row around the autumnal equinox, which has historically given farmers quite enough extra light to finish their crops before the autumnal fatal frosts arrive. The Moon rises an hour later than usual each night, however for many nights straight around the autumnal equinox, the Earth’s tilt and the Moon’s orbital angle coincide perfectly, causing the Moon to arrive only 20 to 30 minutes further than usual each night.

A Name for a Moon in Astrology

One of the only two Moon titles that are both astronomical words and unrelated to any particular month is the Harvest Moon. The term “Harvest Moon” is always applied to the full Moon that is closest to the equinox, which might occur in either September or October. (The full Moon that usually follows the Grain Moon is known as the Hunter’s Moon in astronomy. Either October but rather November is possible.)The Harvest Moon occurred this year on Saturday, September 10.

Is the official start of fall on the Autumnal Equinox 2022?

The first day of fall is, in fact, the autumnal equinox according to the scientific definition of the seasons. The Sun’s location in the sky is used to determine the astronomical seasons. In the Northern Hemisphere, September 1 is typically regarded as the first day of fall according to the scientific definition of periods, which is based on thermal cycling and the Gregorian calendar (March 1 in the Southern Hemisphere).
