The earliest humans spent more time outside than we do. They used the sky as both a clock and a calendar. They could easily see that the sun's path across the sky, the length of the daylight, and the location of the sunrise and sunset all shift in a regular way throughout the year.
We have an equinox twice a year--spring and fall--. Night and day are approximately equal in length.
The name equinox comes from the Latin aequus (equal) and nox (night). Equinox also means that the sun is directly over the equator!
After today, the days get shorter and the nights get longer.
The shorter days are bringing cooler weather. All around us, trees and plants are ending this year's cycle of growth.
Fall is one of my 4 favorite seasons!
