Date and Time:
22 September 2013
Description:
Also known as the first day of Fall or Autumn, the Autumnal Equinox marks one of the two times of the year when the sun is directly above the equator and the length of our daylight and nighttime hours is roughly equal. The other time this occurs is the Vernal Equinox—the first day of Spring.
