Fall Equinox

Today marks the Fall Equinox! It's the first full day of the fall season, so get ready for changing leaves, cooler weather, and all things autumn. Meteorologically speaking, fall began on September 1, but the fall equinox marks the astronomical start of the season.

The term "equinox" refers to the time or date at which the sun crosses the celestial equator, making day and night of equal length. There are two equinoxes each year; on September 22 or 23 and March 20 or 21.

Once the fall equinox begins, daylight in the Northern Hemisphere continues to gradually diminish until the winter solstice. The opposite occurs in the Southern Hemisphere, where daylight continues to grow longer.
