Most recent leap year math. So now we re off by. Each year lasts about 365 days and slightly under 6 hours. Note that in a hundred years 25th leap year the time accumulated will have been 17 hours 53 minutes and 20 seconds multiply 42 minutes and 56 seconds by 25 or almost a day. A leap year has 366 days the extra day is the 29th of february.

25 leap years x 366 days leap year 75 years x 365 days year 36 525 calendar days but in reality we ve had 100 years of 365 2422 days or 36 524 22 days. The intercalary day february 29 is commonly referred to as leap day. How to know if it is a leap year. If it is not such as 1900 then it is not a leap year.

In effect we have an excess time of 42 minutes and 56 seconds every leap year. Leap years have 366 days instead of the usual 365 days and occur almost every four years. We did it in 1800 and 1900. That extra 6 hours adds up to an extra day over the course of 4 years which is why leap years occur almost every 4 years.

Usually a year is a leap year if it is divisible by four like 2012 or 1992. Leap years are those years divisible by 4 except for century years whose number is not divisible by 400. Leap years are any year that can be exactly divided by 4 such as 2016 2020 2024 etc except if it can be exactly divided by 100 then it isn t such as 2100 2200 etc. So once a century on years divisible by 100 we skip leap year.

If it is then that is a leap year. For example the following is the complete list of leap years for the 21st century from year 2001 to 2100. If it can be evenly divided by 4 and 100 such as 2000 then check to see if it is divisible by 400. Therefore 800 1200 and 2000 were leap years but 1700 and 1900 were.

Since no one wants to keep a 128 year cycle they instead decided to skip leap year every 100 years. Leap years have 366 instead of 365 days. Expect another leap year in 4 years. To adjust again a day is taken away on the 100th year.

But leap year gets canceled every hundred years or so to keep the calendar in balance with earth s orbit. Go back more than 100 years and the math gets even more complicated. Now a leap year occurs in every year that is divisible by four but only in century years that are evenly divided by 400.
