Why does February only get 28 days when all the other months get 30 or 31? The answer is part superstition, part politics, and parts astronomy. (Basically, it’s the Romans’ fault)

Special thanksto Dr. Jen Ebbeler from the University of Texas Classics department for walking me through the history of the Roman calendar.
