Thankful Thursday: Knowing How to Leap (Year)

29 Feb

Did you know that today was LEAP DAY? That means it only happens once every 4 years. That is strange for sure.

It all has to do with how much time it takes the Earth to complete its orbit around the Sun. It is supposed to be 365 days but it actually takes the Earth, 365.25 days. So ABOUT every 4 years, they (who are they anyway?) add a leap day. Some calendars, we use one called the Gregorian calendar, actually have a leap month.

People, like Ptolemy III in the 3rd century BC, have been trying to fix this problem forever. In 46 BCE the Julian calendar introduced a leap day every four years, but a problem with the measurement that was used led to a mounting discrepancy throughout several centuries. The Gregorian calendar reformed the concept in 1582 by eliminating leap years in the century years that weren’t exactly divisible by 400. This is why the years 1600 and 2000 were leap years but 1700, 1800, and 1900 were not. And why 2400 will be a leap year but 2100, 2200, and 2300 will not.

My goodness, these humans make things really complicated sometimes.
