Fall Begins Wednesday Morning At 4:21 a.m. Along With the Autumnal Equinox.

Fall begins on September 23, early in the morning at 4:21 A.M. The autumnal equinox is when the Sun appears to cross the celestial equator from north to south. (The celestial equator is the circle in the celestial sphere halfway between the celestial poles).

The word equinox means “equal night”; night and day are about the same length of time. This occurs two times each year: Vernal in late March and Autumnal in late September.

In addition to the (approximately) equal hours of daylight and darkness, the equinoxes are times when the Sun’s apparent motion undergoes the most rapid change. Around the time of the equinoxes, variations in the position on the horizon where the Sun rises and sets can be noticed from one day to the next by alert observers.

Fall is known for it’s festive holidays and it’s harvest season. Fall brings the season when nights can start to drop to freezing while days can be still quite warm. Welcome to Fall!
