As most of you are aware, 2020 is a leap year, meaning there is a February 29 this year. Every four years, the calendar adds a day in order to keep the calendar in line with the earth’s movement around the sun.
Per history.com, while the modern calendar contains 365 days, the actual time it takes for Earth to orbit its star is slightly longer—roughly 365.2421 days. The difference might seem negligible, but over decades and centuries that missing quarter of a day per year can add up. To ensure consistency with the true astronomical year, it is necessary to periodically add in an extra day to make up the lost time and get the calendar back in sync with the heavens.
History.com says the the Egyptians were in fact the first ones to figure out the need for a leap year, but it became more widespread in the reign of Julius Caesar.
The 365 day calendar was finalized in 46 B.C. and included a leap day every four years.
But, it was not enough. Because Caesar’s calendar was running a surplus of about 11 minutes a year, which meant a full day was added every 128 years. By the 14th century, the calendar was 10 days off the solar year.
In 1582, Pope Gregory brought in the Gregorian calendar, which added this little fix. The leap year occurs every four years except for years evenly divisible by 100 and not by 400.
This is the fix that has lasted to this day, although history.com warns that in 10,000 years discrepancies will need to be addressed again.
So there is the explanation for leap year. But it does leave a burning question. Why is it called leap year?
As defined in the dictionary, a leap is to jump or spring a long way (verb), or a forceful jump or quick movement (noun).
We are actually adding a day in leap year, not leaping over one.
Or are we?
In fact, a leap year causes calendar dates to shift ahead two days rather than the standard one. For example March 7, 2019 was a Thursday. On a normal year, March 7, 2020 would be on a Friday. But because 2020 is a leap year, March 7, 2020 is a Saturday. This past Christmas was on a Wednesday, but the coming Christmas will be a Friday. Because of leap year.

“Some say that this custom originated in fifth-century Ireland, where St. Patrick allowed women to take the initiative every four years after St. Brigid complained to him that they were having to wait too long for husbands. Others credit a Scottish law enacted in 1288 under the unmarried Queen Margaret, which allowed a maiden “liberty to bespeak ye man she likes” during leap year. The knave who refused to marry her and could not prove his engagement to another was assessed a fine.” Lynn E. Niedermeir, writing for Western Kentucky University
