I also didn't realize that Leap Years were so complicated! Through the magic of the internets, though, I found out that there are THREE criteria which determine which years are leap years! To wit:
1. Every year that is divisible by four is a leap year;
2. Of those years, if it can be divided by 100, it is NOT a leap year, unless
3. The year is divisible by 400. Then it is a leap year.
You may be asking yourself why we even bother with Leap Years.
Well, the simple truth is that it takes planet Earth approximately 365.2422 days to circle the sun, so every 365-day year we observe leaves a little less than 6 hours unaccounted for. By adding the extra 24-hour day (almost) every four years, we make up for the almost quarter of a day we are off each year. So, per the math:
Thus, the need for a nearly-quadrennial adjustment known as a Leap Day!
Besides holding the honor of being National Surf and Turf Day, other notable Leap Day events include...
