Autumnal Equinox

The Autumnal or Fall Equinox is a floating date around September 22-23 that marks the first day of autumn, when day and night are of equal lengths. The sun crosses the equator moving southward (in the northern hemisphere). The Autumnal Equinox marks the beginning of shorter days and longer nights and the passage into winter. On this day, the sun rises directly in the east and sets directly in the west; the sun will begin to rise at the South Pole after six months of darkness, to bring six months of daylight; and the zenith passes directly overhead on the equator, so the sun casts no shadows. For centuries, friends have gathered to celebrate the day and strengthen their spirits in preparation for the passage into winter.
