Here’s an oddity for those who were taught that noon is the middle of the day, and the sun is due south at 12:00. Neither is true.

Noon this time of year is not 12:00. On Tuesday and Wednesday it is at 12:15 p.m., and it’s getting steadily later, as measured by the time when the sun is at its highest, halfway between sunrise and sunset.

Midnight similarly is at 12:15 a.m. Blame something called the analemma.
