OK, technically it’s not true. The shortest “day” of the year, i.e., the shortest daylight period, is December 21, 9 hours, 15 min., 4 sec. But today the sun sets a bit later than it did yesterday and tomorrow it will be a bit later still.
Separately, I’ve started to note my daily runs on the “Log” page.
For you early morning folks, however, the turn is on January 4.
