There are approximately five million people with February 29 birthdays. They’re known as leapers. (As distinct from lepers, but that’s a little bit too close for comfort!)
It used to be that leapers had issues with insurance companies and banks and other big organizations, who wouldn’t (or couldn’t) recognize February 29 as a legitimate birth date. They were forced to chose February 28 or March 1, instead.
Some websites still don’t accept February 29 as a real date.
And I couldn’t find out where this idea comes from, but it used to be that February 29 was when a woman could propose to a man, rather than waiting for him to get a clue.
Happy leap day!
