Happy Leap Day, Everyone! And Happy Birthday to anyone out there who was unfortunate enough to be born on February 29th. Seriously, how crappy must that be for a child? You only have a birthday every four years, maybe, depending on what year you were born in.
Yeah, that's right, Leap Day doesn't necessarily arrive every four years. The rule is there will be a leap day during every year that is divisible by four, except for years ending in "00," unless that year is also divisible by 400. For example, there was a Leap Day in the year 2000, but not in 1900, and there won't be one in 2100, 2200, or 2300. So, if you were born on February 29, 2000 (like my step-son's half-sister) and you are lucky enough to live for 100 years, you won't have an actual 100th birthday to celebrate. Kinda makes it not worth holding out for, huh?
