What is an equinox?
On any other day of the year, the Earth’s axis tilts a little away from or towards the Sun. But on the two equinoxes, the Earth’s axis tilts neither away from nor towards the Sun, like the illustration shows. The equinoxes occur the moment the sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator. This happens in March and September every year.
Alas, summer is coming to a close because September 22 is, however unfortunate, the first day of fall.
The season officially begins at 4:44 p.m. EDT during the autumnal equinox, when the sun crosses directly over the Earth’s equator and both day and night are about equal. Fall will last a solid three months until the beginning of Winter on December 21, according to the U.S. Naval Observatory.
But all is not lost! There are quite a few reasons to appreciate the season, including some spectacular foliage. It’s basically the time for trees to reevaluate their priorities and start anew. And it really is the perfect time for a hot cup of tea. And campfires. Really, it’s just a time for nature to be beautiful. There are fall breezes. And some stellar food. Because there’s nothing better than a warm cookie on a cold night. It’s a time to reflect, and settle in to a new post-summer groove.
So, fall, we welcome you with open arms.
