Sciencey Stuff ~ Equinox Comparison

It’s been such a long time since I’ve done a regular post, I didn’t know how to begin. Well, I’ve begun, haven’t I? Let’s continue…

March 20, 2021 was the Vernal or Spring Equinox. The day when at the equator there are exactly twelve hours of daylight and twelve hours of darkness. It’s also the first day of Spring.

After tracking the sunset from Summer Solstice (the longest day), through the Autumnal Equinox, to Winter Solstice (the shortest day), I wanted to see if the equinoxes matched up. Theoretically, they should.

I was looking at the cool site I found a while back that has sunset/sunrise times, an interactive map of the stars and planets, and lots of other cool stuff. You just put in your city and it gives everything from that latitude and longitude. Anyway, I wanted to know when San Diego County area was going to have the most equal day. It wasn’t March 20th.

It was actually March 16th. I checked the info for last September and our closest to equal day wasn’t the 22nd, it was the 26th.

So I had a dilemma… should I go with the Official dates, or the actual dates? Would four days make that much of a difference? My Sciencey Stuff wasn’t super scientific, it was mostly just for fun, and to satisfy my curiosity.

Of course I had sunset pictures for the alternate dates. I have sunset pictures of the entire year. I could make a book called A Year Of The Kootie: 365 Days of the Pandemic in Sunsets… Hey! That’s an idea! Maybe I should put one of those copywrite thingies by it. Oh well… my keyboard doesn’t have one.

Anyway, I decided to go with the Official date, since those were the dates I used when I did the big comparison at Winter Solstice. Unfortunately, I was Driving Miss Daisy when the Sun went behind the western hills on the 20th, so I have to use the 19th. I know… not very scientific.

I like that a pair of Parrots were in the shot from March 19, 2021. The pictures are at different magnifications, using different phones, and possibly standing a door’s width different.

My unscientific, Sciencey Stuff Person findings are that the Sun DOES set at the same place on the equinoxes.

Don’t you feel smarter now?
