About Autumnal Equinox
The word equinox comes from the Latin words aequus, meaning “equal,” and nox, meaning “night.”
The sun rises exactly in the east and sets exactly in the west on this day, making day and night equal in length. From this day forward, the sun crosses over the equator to the Southern Hemisphere, meaning it rises and sets in the Southern Hemisphere, meaning that the days will begin to become shorter than nights in the Northern Hemisphere, heralding the arrival of Autumn.
