I browsed through some info on this subject, it's somewhat interesting, so share a quote and link for You.
"Typically in a non-leap year birthday scenario, I might go out to a local pub, and when it gets close to midnight, I'll go into countdown mode — draw a little bit of attention towards myself and say, "My birthday's coming in four, three, two, one — oh, it's over." And then have a slug of beer." HA!

Leap day as a concept has existed for more than 2000 years, and is still associated with age-old customs, folklore and superstition. One of the most well-known traditions is that women propose to their boyfriends, instead of the other way around.
