Leap year.
Been having a gander at the topic of Leap Year, a dangerous time of year for us blokes, seems there are some rules though.
In Greece, getting married in a leap year is considered inauspicious, and the relationship is thought likely to end in divorce.
Women in Finland are advised to propose only on leap-year day -- Feb. 29 -- for good luck. If her boyfriend should refuse, he is required to pay her a "fine": enough fabric to make a skirt.
In Scotland, an unmarried Queen Margaret allegedly enacted a law in 1288 allowing women to propose on leap-year day. But there was a catch: The proposer had to wear a red petticoat (a skirt under her skirt) to warn her intended that she planned to pop the question.
Perhaps the most well-known of the leap-year marriage superstitions belongs to Ireland, where, again, women are advised to propose only on Feb. 29 for good luck. (Anyone remember the 2010 film, "Leap Year"?)
