Today, all over the world, night and day are nearly of equal duration. At the equinox, both in spring and fall, the earth's axis neither tilts away from nor toward the sun. I find it amazing that humans figured this out thousands of years ago without the benefit of the confriming technology that we have today.
I use other methods, less formal, to mark the arrival of spring.....
......magnolias starting to bloom....
.......and people barefoot on the beach. Not exactly science but generally about right. Too bad the ocean water temperature is still about 45 degrees Fahrenheit. Cold water or not, I did see a young man in the water trying to impress his woman friend - ahhh, youth, so much testosterone, so little time....
