Leap Year
Have you ever wondered why we have Leap Year? Here are some fun facts....
A normal year has 365 days. Leap Years have 366 days (the extra day is the 29th of February).
Leap Years are any year that can be evenly divide by 4 (such as 2004, 2008, etc)
except if it can can be evenly divide by 100, then it won't be (such as 2100, 2200, etc)
except if it can can be evenly divide by 400, then it will be (such as 2000, 2400)
Why?
Because the Earth rotates about 365.242375 times a year but a normal year is 365 days, so something has to be done to "catch up" the extra 0.242375 days a year.
So every 4th year we add an extra day (the 29th of February), which makes 365.25 days a year. This is fairly accurate, but will still be wrong by about 1 day every 100 years.
So every 100 years we don't have a leap year, and that results in 365.24 days per year (1 day less in 100 year = -0.01 days per year).
Still not accurate enough! So another rule says that every 400 years is a leap year again. This gets us 365.2425 days per year (1 day regained every 400 years = 0.0025 days per year), which is close enough to 365.242375 not to matter much.
There you have the facts everyone! Enjoy an extra day this year!
