Question

when does autumn come off ?
​

Answer 1

Explanation:

The autumnal equinox is the beginning of "astronomical autumn," which ends with the start of winter. In the Northern Hemisphere, that is from around September 22 to about December 22, though it varies from year to year, according to the NOAA. In the Southern Hemisphere, the season runs from about March 20 to June 21.

Answer 2

Answer:

Autumn is usually defined in the Northern Hemisphere as the period between the autumnal equinox (day and night equal in length), September 22 or 23, and the winter solstice (year's shortest day), December 21 or 22; and in the Southern Hemisphere as the period between March 20 or 21 and June 21 or 22.
