Thursday was the fall equinox here in the U.S. That means the day and night were supposed to be of equal length, right? I had blissfully assumed that for years, but when I was watching for it on my World Clock on my iPad it didn’t happen. The day lengths for cities in the both the northern and southern hemispheres were all longer than 12 hours. The time between sunrise and sunset for Helsinki was 12 hours and 11 minutes, for Auckland, 12 hours and 8 minutes. Being naive, that was a surprise to me. It turns out it’s the equilux when the day and night are of equal length and it happens at different times, depending where we are:
So, when is the equilux? Well, the date depends on where you live.
In the Southern Hemisphere, the equilux happens a few days before the September equinox; for Northern Hemisphere dwellers, it is a few days after the equinox.

Is it important? Probably not, but it was fun noticing it and finding out what was going on. Just another example of the joy of being a geek. We’re never bored.

Interesting. I do believe that the sun rises due east on the one day, right? Or not?
Yes, that should be right. The equinox is when the earth isn’t tilted.
Isn’t the internet wonderful…till we can look up all this stuff if we want!
Yes! I’m in hog heaven.
That’s very interesting and something I didn’t know. Gotta love the internet. It makes researching such things so easy.
I know. I’m in hog heaven.
I am with you on the GEEK! I would be b1.ored with life without all the geeky stuff. I am very aware of the daylight hours because of walking Beau. our walk time changes daily and weekly it jumps about 5 minutes.
we went from leaving at 6:30 to yesterday at 7:05, makes me aware of the up and down of the daylight. we still have 12 and 1/2 hours of daylight even now and I know from Bob that up north the daylight is much shorter than ours.
The reason I started watching the app was because Angus takes Sophie for morning walks and they’re now living near St. Andrews, Scotland: https://bobnsophie.blogspot.com/ The sunrise will get later and later so it’ll be fun to watch.
I love these random bits of intel … what I call Jeopardy! fodder.
That’s a great name for it!
