The first day of Fall (or Autumn), officially referred to as the Autumnal Equinox, begins at 11:09pm EDT on September 22nd. This is one of two days in the year when the Earth's axis is neither tilted toward or away from the Sun. The word equinox is derived from the Latin words aequus (equal) and nox (night). In reality, the day is longer than the night at an equinox due to our sun's rays being refracted by our atmosphere. To figure out when the sun will rise and set at your location, click here.
