The Vernal Equinox is March 20th, the Summer Solstice is June 21st and the Winter Solstice is Dec 21st. These stay the same every year. Can anyone tell me why the Autumnal Equinox is either Sept. 22 or 23rd? I am very confused by this and have always actually thought it was Sept 21.

I don't know why. I seems it just changes randomly. Just stick by the change. You'll live longer.

actually, all of the Solstices and Equinoxes are changeable dates. they don't fall on the same date each year. so it's not just the autumnal Equinox that varies, but all of the Solstices and Equinoxes.
