Not quite "Sadie Hawkins Day" but, close enough.
Cribbed from Wikipedia:

There is a tradition that women may make a proposal of marriage to men only in leap years, further restricted in some cases to only February 29. There is a tradition that in 1288 the Scottish parliament under Queen Margaret legislated that any woman could propose in Leap Year; few parliament records of that time exist, and none concern February 29. Another component of this tradition was that if the man rejects the proposal, he should soften the blow by providing a kiss, one pound currency, and a pair of gloves (some later sources say a silk gown). There were similar notions in France and Switzerland.

Sadie Hawkins Day is a fictional holiday that originates in Al Capp's comic strip Li'l Abner. It was a day-long event observed in Canada and in the United States on the Saturday that follows November 9, named after Sadie Hawkins, "the homeliest gal in all them hills." Each year on Sadie Hawkins Day the unmarried women of Dogpatch pursued the single men. If a woman caught a man and dragged him back to the starting line by sundown, he had to marry her.
