Saturday was the last day of summer 2013, which means another fall (or autumnal) equinox, is coming on Sunday.But what is the autumnal equinox? Most people don't quite know, so let North Druid Hills Patch serve as the great explainer for all things equinoctial.
Equinoxes fall on the halfway point between solstices and occur, according to the Washington Post, "when the sun crosses the equator and day and night are of roughly equal length, everywhere in the world."
The nearly equal 12 hours of light and darkness can be attributed to the Earth's lack of an axial tilt on the day of the equinox. In fact, the word equinox is derived from the Latin words aequus, meaning equal, and nox, meaning night.
See ya next year, summer. Hello fall, and happy autumnal equinox!
