Autumnal Equinox marks first day of fall

natureSep 22, 20261964,288

The autumnal equinox arrives Tuesday, September 22, 2026, with the U.S. Naval Observatory placing the precise moment in the evening. The sun crosses the celestial equator so the Northern Hemisphere moves into autumn and the Southern Hemisphere into spring, producing roughly equal hours of day and night. In some U.S. cities the equinox also lines up with street grids to create a striking sunrise or sunset framing known as "Chicagohenge," visible on wide east, west streets such as Kinzie and Madison. Michelle Nichols of the Adler Planetarium says tall buildings and street width accentuate that framing, and Geoff Boeing of the University of Southern California links the effect to long histories of cities aligned with the skies. Other grid cities like Washington, D.C., and Phoenix can produce similar "henge" moments once or twice a year. Photographers and residents often gather downtown to view and photograph these alignments around the equinox.

Given our lack of prioritization of public education, I have grave concerns "equinox" will be a very unfamiliar term to many.

On this the first day of Libra season I offer you Gen X autumnal equinox vibes. First full program without injury adjustments. Deadlift is good. Femur tracking properly. He makes me jump now. I hate it. Airplanes still humbling.

I do the new year rituals — meditation, burning, planning — on my birthday instead. Because I like to feel special. Today marks slowdown season for me until second week of January. It’s been an eventful 12 months. I’m happy with it but, uh, don't want to do any of it again.

Used to watch your videos and worry you'd get injured. Then a big hungry goat jerked me around last winter and I had back surgery to fix. Surgeon said, Load load load and deadlift, squat, at six weeks. I'm 100% recovered (very lucky). Wouldn't have even considered if you didn't post these.

the glide in your knees and hips is inspiring !!!

Happy September equinox! That's the autumnal one for those of us in the northern hemisphere, spring in the south. I explain it in two different ways in today's newsletter, plus what it means for the length of daytime. badastronomy.beehiiv.com/p/happy-sept... 🧪 🔭

Good morning Robert. Fall in Michigan is so pretty. It's what comes after it that I don't like!

Happy Autumnal Equinox! The shift into the dark part of the year when we experience inward reflection. A time to prepare for the coming hibernation. Today is a day of balance between sunshine and darkness. This is the season of harvest. Mother Nature takes time to show off her beauty.

Excellent family portrait, though. Mom gets points for lining you up, and all three of you get points (treats) for staying.

Please note: the autumnal equinox happens tonight, so if you are feeling like it’s getting dark out, like it’s getting darker out, like it’s getting even darker out, just know that you are right in multiple ways.

It's Mabon! The Autumnal Equinox - half sun/half dark. A reminder that balance WILL occur, if we let it. "This too shall pass" So enjoy the day, and remember that no matter how good or bad things get, It's Temporary!

The scene from the 1946 film THE POSTMAN ALWAYS RINGS TWICE.
Lana Turner and John Garfield are on a cliff above the ocean. Lana is wearing a plain two-piece white bathing suit and John Garfield is wearing black bathing trunks with a white belt. They appear to be in a struggle. Lana has her head of blonde hair tossed back and John is trying to hold her close.
