This year, observing the Autumnal Equinox has proved particularly challenging.
For a vast percentage of modern society, the autumnal equinox, if noticed at all, is a specific date on the calendar: September 21st. While the equinox has fallen on the 21st for the last several years, it can fall anywhere between September 21st and 24th, inclusive. This year it fell on September 23rd—sort of . . . . The equinox actually occurred at 3:50 a.m. Eastern Daylight Time. So, for Alaska, it occurred at 11:50 p.m. September 22nd.
