According to English law, February 29th was ignored and had no legal status. Folks assumed that traditions would also have no status on that day. It was also reasoned that since the leap year day existed to fix a problem in the calendar, it could also be used to fix an old and unjust custom that only let men propose marriage.
The first documentation of this practice dates back to 1288, when Scotland supposedly passed a law that allowed women to propose marriage to the man of their choice in that year. Tradition states they also made it law that any man who declined a proposal in a leap year must pay a fine. The fine could range from a kiss to payment for a silk dress or a pair of gloves.
