At/On the equator, it’s pretty much equal every day. On the equinoxes (like today), the days and nights are pretty much equal all over the earth – from the North Pole to the South Pole.
Just checked. On 3/17, the day was 12 hours, 39 seconds, which is as close to perfectly equal as it gets. Today, it’s 12:08:50. That’s at my latitude (about 40). If your latitude is 30 north, it was on the 16th.
“Equilux”! I like it and always observe it, but never knew it was called that.
BTW, “daylight saving time” puts sunrise and sunset at 7:00 a.m and p.m. respectively, instead of the perfectly logical 6:00, half the day before and after the noon midpoint. Standard time is called that for a reason.

It is possible to be too smart sometimes, but thanks for the info.

When people think Caulfield is as enlightening as he is annoying, then he isn’t trying hard enough.

My! Here the cleverness and the humanness are in perfect balance!—it’s not too clever, nor too little, I say. (Or does it just seem . . . ?)

I’m pretty sure he’s a lot more annoying than enlightening.

Then why are we on DST now. Aren’t we supposed to get an extra hour of light? /s

If the solstices are mid -summer and -winter, then the equinoxes are mid -spring and -autumn…

Happy Astronomical Spring. Meteorological Spring was 20 days ago.

The astronomical first day of spring. And Nowruz, the Persian New Year!
