September Equinox on Saturday

The September Equinox begins fall in the Northern Hemisphere and spring in the Southern Hemisphere on Saturday, September 23 (based on Coordinated Universal Time). The exact time of the equinox is 12:03 a.m. Eastern Time and 4:03 a.m. UTC. My article The Four Seasons tells about this significant day, when the sun rises at the South Pole and sets at the North Pole, among other phenomenon.
