In North America, the fall season starts around September 22 and ends around December 21. Each year the exact date of the beginning and end of fall changes, but the dates are generally around those times.
The autumnal equinox is one of the two equinoxes every year, the other being in March. This is when the sun shines directly on the equator, making the length of day and night almost equal to one another all over the world. The word equinox is a Latin word that means “equal night.”
During the fall equinox, many cultures have different celebrations. In ancient Greece, the time of the September equinox is the time to perform different rituals for security and protection.
