Leap Day is a Day Out of the Ordinary


An extra day every 4 yrs is something to celebrate.

On Leap Day interesting things have happened throughout history. Everyone knows we have 365 days on the calendar, but nearly every 4 years we get an extra day.

This happens since nearly every 4 years the dates on the calendar do not line up with the true year, or the amount of time it takes the Earth to orbit the sun. In other words, leap year is the year an extra day is added to the month of February to synchronize the seasons with the calendar.

If you think having a leap year is confusing, wait until we talk about the “leap second.” In both cases, with the Leap Day and leap sec, scientists adjust the calendar and time to bring the solar day into alignment with Universal Time used in sensitive applications, aviation and the internet.

A leap sec accounts for a difference in the gravitational pull on the Earth from the Sun and Moon. As the Earth rotates it slows imperceptibly, so 1 sec of time is added intermittently to the clock.

The last one happened at midnight December 31, 2016, and the next is scheduled for June 30, 2020. The extra sec has been added 27X since Y 1972. While a leap sec may be fascinating, it is unnoticeable in a day. But, an extra day every 4 yrs is something to celebrate.

The addition of 1 day every 4 yrs is due to the Sun. It takes the Earth 365.242189 days to rotate around the Sun 1 time.

Expressed another way, circling the Sun takes 365 days, 5 hrs, 48 mins and 45 secs. When calendars to mark the year were 1st created, they were based on 365 days in a year without any additional hrs or mins.

The change began in 46 BC when Julius Caesar asked the Greek astronomer Sosigenes to adjust the Roman calendar with the seasons, and 1 of the adjustments called for an extra day to keep the calendar, Earth and Sun in sync. But too many leap years created another problem.

By Y 1577 the difference between the number of days in the Julian calendar base, 365.25 days, and the actual number of days, 365.24219 resulted in the calendar being 10 days out of alignment with the Earth’s position relative to the Sun.

To correct for the 11-min discrepancy, Pope Gregory XIII created the Gregorian calendar. At the same time, 10 days were dropped from October that year and February 29 became the official additional day.

The point was to make sure the Spring and Autumn equinoxes fell on the same days each year. The equinox describes the tilt of the Earth’s equator in relation to the Sun over the course of 1 year.

The word is from Latin, meaning aequus (equal) and nox (night) since on the Spring and Autumn equinox the length of day and night are each 12 hrs at all points except at the North and South Poles.

Although leap year happens on your calendar every 4 yrs, it does not happen exactly every 4 yrs. During Leap Year the extra day is added to the end of February making that year 366 days.

If the solar year was precisely 6 hrs longer than the calendar year, then adding 1 day every 4 yrs would make up for the 24 hrs lost.

Instead, the time difference is 11 mins short of 6 hrs. Without the addition of a leap year the calendar would be off 24 days every 100 yrs, which would quickly put Christmas during Summer in the Northern Hemisphere. However, if a leap year happens exactly every 4 yrs, the calendar would also shift, albeit more slowly, by 11 mins each yr.

So, a Gregorian calendar has a slightly more complex set of guidelines. The criteria that helps identify which yrs are leap years begins with the rule of division. If the year is divisible by 4 then it is a leap year. However, yrs that mark centuries are different. These must be divisible by 400. This meant 2000 and 2400 are leap years but 2200 will not be.

The idea of adding an extra day to the calendar every 4 yrs seemed silly to some.

One British play poked fun at it with the inclusion of a joke that on that day, women could act like men. The play was meant to be ridiculous but by the 1700’s a tradition was born.

Now it’s known as Bachelor’s Day in the UK or Sadie Hawkins Day in the US, a day when it is acceptable for women to ask men for their “hand in marriage.”

The tradition continues to be popular in the UK, inspiring some stores to offer discount wedding packages to those who said yes on Leap Day.

One legend has it that women proposing on Leap Day dates back to when English law did not recognize February 29.

The idea was if a day has no legal status it was acceptable to break tradition.

In other cultures, a man would be fined if he said “no” to a woman’s proposal of marriage on Leap Day. In Denmark he was bound to give her 12 pairs of gloves and in Finland, cloth for a skirt.

Traditions attached to marriages in Leap Year do not stop there.

In Greece, 20% of couples don’t get married in Leap Year as they believe it is bad luck. Engaged couples are not the only ones who think there may be some bad luck in the leap year.

In Scotland they say, “Leap Year was ne’er a good sheep year.” as they thought livestock did not thrive in those years.

Mother Nature Network reports the Italians go a bit further:

“In Italy, where they say ‘anno bisesto, anno funesto’ (which means leap year, doom year), there are warnings against planning special activities such as weddings. The reason? ‘Anno bisesto tutte le donne senza sesto’ which means ‘In a leap year, women are erratic.’”

The twin cities Anthony, Texas, and Anthony, New Mexico, took the concept of Leap Year to heart and declared themselves the leap year capitals of the world.

Each year they throw a Worldwide Leap Year Festival that goes on for 4 days, including a birthday party for those who were born on the day.

The festival was proposed in 1988 when 2 women born on Leap Day, 1 in each city, proposed the event that includes parades, dancing and tours. The gala has attracted people from around the world.

If the chances of being born on Leap Day are that low, then what are the odds that 1 family might have 3 children born on consecutive leap days?

History.com reports that the Henriksens of Norway made the Guinness Book of World Records when Heidi, Olav and Leif-Martin were born in 1960, 1964 and 1968, respectively.

Others who claim Leap Day as the day of their birth include singer actress Dinah Shore, motivational speaker Tony Robbins and big band leader Jimmy Dorsey.

More than a few interesting events have happened on February 29.

One quaint item is February 30. This rare date happened in Y 1712 in Sweden and Finland when they added the day as they switched from the Julian to the Gregorian calendar.

Here are several more happenings on a day that happens just once every 4 years, as follows:

•Salem Witch Trials — The 1st arrest warrants were issued on February 29, 1692, for Sarah Good, Sarah Osborne and Tituba. Good hung after refusing to confess, Osborne perished in prison and Tituba admitted to being a witch, earning her release a year later.

•La Bougie du Sapeur — You can purchase this French newspaper published once every 4 years for €4 at a newsstand. The publication, The Sapper’s Candle, is a spoof that takes its lead from a “Sapper,” the name for a military engineer known for digging trenches and tunnels.

•Buddy Holly’s Glasses — The lost was found on February 29, 1980, when county Sheriff Jerry Allen found the famed singer’s trademark glasses buried in an envelope in old court records. The glasses were initially recovered in the Spring after the plane crash that killed Holly and the Big Bopper in the Winter of 1959. They were then sealed in a manila envelope. It was over 20 years later when the frames were returned to Holly’s widow.

•Hank Aaron — February 29, 1972, Hank Aaron became the highest paid major league baseball player in history, earning a $200,000 contract to play in Atlanta.
