For those who aren't familiar with the complexities of the Gregorian calendar, tomorrow is certainly going to be unique. During Leap Years such as 2012, an extra day (February 29) is added to the datebook in order to balance out the eternal rotation of the earth around the sun.
Since it happens every four years, Leap Day has a bit of folklore and an aura of kookiness attached to it (hence that nutty 30 Rock episode that aired last week). Supposedly, it was once considered the only day when women can partake in "ladies privilege" and propose to men, as depicted in that execrable Amy Adams rom-com from a few years back.
It's also yet another excuse to party, which is what the proprietors few local bars and club are planning on doing with special fetes planned for the occasion.
