Thirty days hath September,
April, June and November;
All the rest have thirty-one
Save February, she alone
Hath eight days and a score
Til leap year gives her one day more.
Leap Day as a concept has existed for more than 2000 years, and is still associated with age-old traditions, folklore and superstition. One of the most popular traditions is that women propose to their boyfriends.
‘Leap Day’ is February 29, which is an extra (intercalary) day added during a Leap Year, making the year 366 days long – and not 365 days, like a common (normal) year. Nearly every 4 years is a Leap Year in our modern Gregorian Calendar.
Ever since Leap Years were first introduced over 2000 years ago with the transition from the Roman Calendar to the Julian Calendar in 45 BCE (Before Common Era), Leap Day has been associated with age-old Leap Day traditions and folklore.
Women propose to their men:
According to an old Irish legend, or possibly history, St Bridget struck a deal with St Patrick to allow women to propose to men – and not just the other way around – every 4 years. This is believed to have been introduced to balance the traditional roles of men and women in a similar way to how Leap Day balances the calendar.
In some places, Leap Day has been known as “Bachelors’ Day” for the same reason. A man was expected to pay a penalty, such as a gown or money, if he refused a marriage proposal from a woman on Leap Day. In many European countries, especially in the upper classes of society, tradition dictates that any man who refuses a woman’s proposal on February 29 has to buy her 12 pairs of gloves. The intention is that the woman can wear the gloves to hide the embarrassment of not having an engagement ring. During the middle ages there were laws governing this tradition.
World Record of Leap Day Babies:
People born on February 29 are all invited to join The Honor society of Leap Year Day Babies.
According to the Guinness Book of Records, there are world record holders both of a family producing three consecutive generations born on February 29 and of the number of children born on February 29 in the same family.
In Scotland, it used to be considered unlucky for someone to be born on Leap Day, just like Friday 13th is considered an unlucky day by many. In Greece it’s said to be unlucky for couples to marry during a Leap Year, and especially on Leap Day.
St Oswald’s Day:
Leap Day is also St Oswald’s Day, named after an archbishop of York who died on February 29, 992. The memorial is celebrated on February 29 during Leap Years and on February 28 during common years.
Why do we need Leap Years?
Leap Years are needed to keep our calendar in alignment with the Earth’s revolutions around the sun. It takes the Earth approximately 365.242199 days – or 365 days, 5 hours, 48 minutes, and 46 seconds (a tropical year) – to circle once around the Sun.
However, the Gregorian calendar has only 365 days in a year, so if we didn’t add a day on February 29 nearly every 4 years, we would lose almost six hours off our calendar every year. After only 100 years, our calendar would be off by approximately 24 days!
How do we calculate Leap Years?
In the Gregorian calendar 3 criteria must be met to be a leap year:
1) The year is evenly divisible by 4;
2) If the year can be evenly divided by 100, it is NOT a leap year, unless;
3) The year is also evenly divisible by 400. Then it is a leap year.
