1. History of Leap Year

A long time ago in Ancient Egypt, some dudes were goofing around and figured out that something didn't exactly line up between the solar calendar and the man-made one. They realized that it takes the Earth 365 days, five hours, 48 minutes, and 46 seconds to travel around the some. All that extra change allotted for an extra day once every four years. Julius Caesar, everyone's favorite Roman dictator, added that year into the calendar.

Here's something we don't hear about much. A tradition of women proposing to men began in fifth century (500 BC) in Ireland. St. Bridget complained to St. Patrick about how women had to sit around and wait for male suitors to purpose.
