2019's autumnal equinox, also known as the September equinox or the fall equinox, arrives on September 23 in North America. Here in the U.S., this date often coincides with the beginning of crisper air, falling leaves, and the first hints of the changing seasons.
The autumnal equinox is the astronomical start of the fall season in the Northern Hemisphere and the start of the spring season in the Southern Hemisphere.
The word “equinox” comes from a combination of the Latin word aequus, meaning “equal,” and the Latin word #nox, meaning “night.”
On the equinox, day and night are about equal in terms of length. In many cultures, the equinoxes are used as a day to pause, reflect, and prepare for the changing foliage and shifting weather.
