When is the first day of autumn?

The first day of autumn depends on which definition you use:

  • September 22 or 23 (in the Northern Hemisphere) marks the autumn equinox, the beginning of astronomical autumn.
  • September 1 marks the beginning of meteorological autumn, which ends on November 30.

Given that autumn starts in September for both definitions, this month is a good time to wish your family and friends a happy autumn.
