The autumn equinox arrives on September 22, which means that fall officially begins on Thursday. With the beginning of fall, the sun will sink lower and nights will get longer.

The autumn equinox takes place at 10.21 am ET (2.20 pm UTC) on Thursday, which will officially mark the start of fall in the Northern Hemisphere and spring in the Southern Hemisphere, according to National Geographic.

The word "equinox" is derived from Latin, meaning "equal nights." Equinox is that time of the year when day and night are of around the same length, i.e. 12-hours. There are two equinoxes that take place every year, one in September and another in March. The equinox in September happens when the sun crosses the celestial equator and heads southward.

There was an expectancy about its sounds and shapes: the distant thunk pomp of leather and young bodies on the practice field near her house made her think of bands and cold Coca-Colas, parched peanuts and the sight of people's breath in the air.

Fall was hot supper time with everything to eat one missed in the morning when too sleepy to enjoy it." ― Harper Lee.
