It’s been a fun Leap Day, hasn’t it? But a lot of monks had to give up their lives to give you 24-bonus hours every four years. You owe it to them (and yourself) to know the full story behind “Leap Day.”
Well, it’s been nice having a bonus day this year, hasn’t it? But while Leap Day might be a bigger deal for some than it is for others (Happy 24th birthday, Superman), not everyone’s a fan.
The irregular rules behind an extra day that regularly occurs only once every four years … sometimes.
As a general rule, leap days occur every four years. However, there are exceptions to this rule. For instance, during the turn of each century, we skip a leap year. Even if the year is divisible by four, we do not add an extra day in the years that end in 00.
Nonetheless, there is also an exception to this exception. If the year is a multiple of 400, we do include an additional leap day. At the turn of the millennium, despite being divisible by 100, the year 2000 did indeed have a February 29th because it was also divisible by 400.
Got that? Good. Now if you want to know more, tune into this article from the BBC.
But why February 29th?
That’s actually a good question. As presented in this article on The Conversation, the leap year (and leap day) appears to be the work of some obsessive compulsive monks from the Middle Ages. While it might make sense to add an extra day to the year at its end (meaning December 32nd), the original plan was to add the extra day on February 24th … which leads to a much more convoluted series of consideration.
So, shout out to Byrhtferth of Ramsey (who had a bissextile day fetish … and it’s not what you think that is) and all of the other medieval monks who contributed to the creation of February 29th as we know it today.
The most helpful explanation I could find about why February 29th appears on our calendar every four years (or so) is this article from NPR. Reporter Rachel Treisman manages to sum up hundreds of years of calendar niggling into a concise 2-minute audio report which is, in fact, 2-minutes long no matter what day of the year it might be.
So let’s celebrate it, already.
People born on Leap Day are known as “Leaplings” (no, seriously) and range from Dennis Farina and Dinah Shore to Ja Rule and Tony Robbins. Interested in the list of who’s who? They’re all just a bunch of kids, really, but here you are: People | AL.com | Town & Country
