September 22 - Equinox

Equinox - There is an equinox (autumn and spring) or a solstice (summer and winter) on approximately the 21st day of the last month of every quarter of the calendar year. On a day which has an equinox, the center of the Sun will spend a nearly equal amount of time above and below the horizon at every location on Earth and night and day will be of nearly the same length. The word equinox derives from the Latin words aequus (equal) and nox (night). In reality, the day is longer than the night at an equinox.

The autumnal equinox occurs this afternoon at precisely 15:44 UT.

Happy Autumn!

I like the way the colors look in the letters of the words that spell Happy Autumn. Very pretty!
