A Leap Day Tradition?
According to my sources, "Leap Day" (February 29th) is the one day of the year on which women can propose to men, based upon tradition. Since the day had no legal status, it was assumed that tradition also had no status, so women took advantage of this and proposed to the men that they wanted to marry.
The tradition is derived from an old Irish legend wherein (allegedly) in the 5th Century a nun by the name of St. Bridget petitioned St. Patrick, on behalf of all women, so that they have a more active role in choosing their husbands. As a result of this request, women were allowed to propose to men once every four years.
So, all the eligible females out there better take advantage of the opportunity; it doesn't last long and won't happen again for another four years...
