About First Day of Fall

The first day of Fall 2027 (the Autumnal Equinox) is on Wednesday, September 22nd. Day and night are nearly equal in length. It marks the astronomical start of autumn, bringing cooler temperatures, changing leaf colors, and the beginning of harvest season across the Northern Hemisphere.

History & Significance

The Autumnal Equinox has been observed by cultures worldwide for millennia. Ancient harvest festivals like Mabon, the Mid-Autumn Festival in China, and Thanksgiving traditions trace their roots to equinox celebrations. The word "equinox" comes from Latin meaning "equal night," reflecting the near-equal hours of daylight and darkness on this date.
