What is the time and history of the calendar? How did we end up with the calendar we use today? Why do we celebrate Washington’s birthday on the wrong date?

Sethanne Howard is a retired American research astronomer and physicist. She most recently worked as the Chief of the Nautical Almanac Office at the US Naval Observatory in Washington, DC.
