Leap Year (aka Sadie Hawkins Day) The tradition actually started with St. Patrick and St. Bridget (5th Century) in Ireland. St. Bridget complained to St. Patrick that the sisters in her nunnery were in despair because the prevailing tradition at the time — that women had to wait for a proposal of marriage from a man. St. Patrick agreed to allow women to propose to men every four years, during Leap Year. Afterwards, Bridget proposed to Patrick only to be turned down!?)
