In just over a day – 3:20 PM tomorrow at the vernal equinox to be precise – Summer 2021 will be in the books. Here’s hoping you get a little of that summer light before it’s all gone!

The Old Farmer’s Almanac says that the autumnal equinox arrives tomorrow, Tuesday, September 22 at 9:31 AM:
The word “equinox” comes from Latin aequus, meaning “equal,” and nox, “night.” On the equinox, day and night are roughly equal in length. (See more about this below.)
During the equinox, the Sun crosses what we call the “celestial equator”—an imaginary extension of Earth’s equator line into space. The equinox occurs precisely when the Sun’s center passes through this line. When the Sun crosses the equator from north to south, this marks the autumnal equinox; when it crosses from south to north, this marks the vernal equinox.

The vernal equinox heralding the start of Spring happened at 11:50 PM Thursday night. EarthSky editor Deborah Byrd’s article on the vernal equinox has a ton of great information, video, and illustrations and explains:
…there’s nothing official about it, it’s traditional to say the upcoming March or vernal equinox signals the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. This equinox does provide a hallmark for the sun’s motion in our sky, marking that special moment when the sun crosses the celestial equator going from south to north … At the equinox, Earth’s two hemispheres are receiving the sun’s rays equally. Night and day are approximately equal in length. The word equinox comes from the Latin aequus (equal) and nox (night).
