A black and white image of a Roman coin depicting Julius Caesar. The coin is slightly damaged around the edges. The image accompanies a description of how Julius Caesar, advised by the Alexandrian astronomer Sosigenes, reformed the calendar to include leap years, accounting for Earth's orbital period around the Sun. This is in relation to the astronomical origins of leap day.

Astronomy Picture from 29/02/2004

Recently balanced my checkbook and in the part of the ledger where you fill in the day’s date I accidentally wrote ten instead of twelve for the month. What can I say? Old habits die hard.
