If you live in the Northern Hemisphere, today is the first day since March 17th with less day than night. Yes, Friday was the autumnal equinox, when the earth's axis was perpendicular to its orbital plane. But because the atmosphere refracts the sun's light about 0.85°, days are always just a little longer than nights on equinoxes.
