The Autumnal Equinox, also known as the fall equinox, is a natural event that occurs twice a year, in September in the northern hemisphere and in March in the southern hemisphere. It marks the moment when the sun crosses the celestial equator, resulting in an equal amount of daylight and darkness. It signals the start of the fall season in the northern hemisphere.
