The Inconstant Year
The Autumnal Equinox was last Wednesday, September 23. This was the first day of autumn. It's also a special day for the earth, along with the Vernal Equinox on March 20, and the Summer and Winter Solstices on June 21 and December 21. On the solstices, the earth is most tilted toward or away from the sun. On the equinox, it's in the middle, and day and night are (nearly) the same. I counted days on my calendar and found that there are 186 summer days between the spring and fall equinoxes, but only 179 days between fall and spring. What gives?
