Answer Details
On September 23 each year, the earth experiences the autumnal equinox. An equinox occurs twice a year when the sun is exactly above the equator and day and night are of approximately equal length. During the autumnal equinox, the tilt of the earth's axis is inclined neither away from nor towards the sun. This results in nearly equal amounts of daylight and darkness at all latitudes, which marks the start of autumn in the Northern Hemisphere and spring in the Southern Hemisphere. The autumnal equinox occurs annually on September 23 in the Northern Hemisphere and March 20 or 21 in the Southern Hemisphere. Therefore, on September 23 each year, the earth experiences the autumnal equinox.
