autumnal equinox 4:44pm est...,


The autumnal equinox occurs at 4:44 p.m. EDT (20:44 UT) on Sunday, Sept. 22nd, when the Sun crosses the equator heading south. This marks the beginning of autumn in the northern hemisphere and spring in the southern hemisphere. You will know the equinox is near when you find yourself nearly-blinded while driving down east-west roads this afternoon.
