Rules of courtship are quite different these days, but long ago women who were hoping to marry had to wait for their beau to propose. They were not "allowed" to pop the question themselves, except on one day: on a leap year (February 29th) -- also known as Sadie Hawkins Day -- which occurs every four years.
The tradition dates back hundreds of years, to when the leap year was not recognized by English law; the day was simply "leapt over" and ignored. Since it had no legal status, formal traditions did not apply on this day. Consequently, women who were not content to wait for a proposal took advantage of this anomaly and popped the question themselves. It was also thought that since leap year corrected the discrepancy between the calendar year (365 days) and the time it takes for the earth to complete one orbit of the sun (365 days and 6 hours), it was an opportunity for women to correct a tradition that was one-sided and unfair.
Thankfully time has marched on. Rightly or wrongly, romantic traditions still live on. A woman wants to be desired and sought after and she never wants to be referred to as 'Diana Goddess of the Hunt'.
I have a friend who should seize the day today. The only time she is wasting and heart she is breaking is her own. The worst scenario is, that she has to face the reality that Olva Ovum has now turned into a lizard and it’s time to plan ahead for her future retirement.
Go for it Sadie, you have nothing to lose but the lout!
