Autumnal Equinox (Northern Hemisphere)

September 22, 2020

The word "equinox" stems from two latin words, aequus (meaning "equal") and nox (meaning "night"). It is when the length of the day is exactly equal to the length of the night.

It's halfway between the solstices, when the Sun reaches its highest or lowest point in the sky.
