June solstice was at 02:40 UT (22:40 EDT); it's summer in the Northern Hemisphere & winter in the Southern. Hope everyone has a great season; also hope most of us in the U.S. (or really anywhere) don't melt over the next week, or maybe even all summer. #solstice #astronomy #calendars #timekeeping

There are some vague hints that the Greeks also learned about tithis from the Babylonians, but the evidence there is unfortunately scanty.
