Leap year (Leap Day) is celebrated every February 29 and according to the Gregorian calendar, and is actually present every four years. The year 1900 was not a leap year but the year 2000 was. A year with a leap day is called a Leap Year. February 29 is the 60th day on the Gregorian calendar. In the Chinese calendar, this day only appears in the years of rat, monkey, and dragon.
Even though the most modern calendar years have 365 days, the comprehensive revolution of the Earth around the Sun takes about 365 days and 6 hours. The additional 24 hours will consequently be built up every four years. This 4th year needs an additional calendar day so that it will align in the calendar with the sun’s noticeable position.
Without the additional day, the seasons may move back in the calendar, and it may lead in the confusion when activities are undertaken based in the ecology, weather or daylight hours. Furthermore, the Earth takes 365 days 5 hours and 49 minutes in completing its orbit (or about 365.2425 days). This fact is based from the Alfonsine Tables.
The Gregorian calendar often repeats itself in every 400 years or 20,871 weeks, and it has 97 leap days. Even today, the usual days where February 29 falls are in order are Thursday, Tuesday, Sunday, Wednesday, Monday, and Saturday.
Actually, the Leap Day is represented as a part of the Reform of Julian. Terminalia which is February 24 is being doubled so that is why it was reformed as the “bis sextum or double six”. However, there is an exception and those are the primary days. The double six days are recognized as the bissextile or intercalated days from the time of the third century. And February 29 became the leap day when the Roman System is being changed by the numbering of sequential in the Middle Ages.
The Egyptians were the first people who personally added a Leap Day in every four years. However, the Romans were still the very first people who decided to make February 29 as the official date of Leap Day.
People who were born on February 29 are called Leaplings. Individuals who believe in bad luck usually get married in the leap year. There are some places in the world today that on Leap Day, a woman has the freedom to propose marriage to a man.
Rumor Has It …
… that during the song “The Twelve Days of Christmas” the ten lords a-leaping were actually leaplings who should only make an appearance in this song every 4 years. The other 3 years, the lyrics should read, “10 Dukes a-ducking.” True story, sort of.
