Autumnal Equinox

Happy (but a little belated) Autumnal Equinox. This of course is the moment when the sun is half way in its southerly journey in our skies. On this day a man can stand in the shade of his own sombrero by standing on the equator. Also the sun rises exactly in the east and set exactly in the west on this day. Finally, everyone on the planet (except for Indiana) has 12 hours of daylight and 12 hours of darkness.

It is NOT true that you can stand an egg on its narrow end on this day (nor on the Vernal Equinox). Actually sometimes you can but you can on any day.
