Today is Leap Day, the extra day added to the end of February every four years since the adaptation of the Gregorian calendar in 1582 to ensure that the rest of the calendar remains properly aligned with the seasons. At first the adjusted calendar was accepted only by Italy, Poland, Portugal and Spain. Over the centuries it was introduced elsewhere, reluctantly, sometimes followed by public rioting, with Great Britain’s American colonies making the change in 1752, and China being the last in 1912.
According to tradition, Leap Day is the day that a woman may propose marriage to a man, instead of the other way around. And if he declines, he is obliged to compensate her with a gift of new gloves, presumably to hide her shameful ring-free hands. Think twice, ladies, before testing to see if this still works; he may surprise you and say Yes.
(Once every four years they get to celebrate on the correct date)
