- NEW!
Help answer this question below.
Every year never ends evenly. There is always 1/4 of a day extra on a year. So we just add an extra day to the leap year.
It actually takes the earth 365.25 years to make the trip around the sun. For simplicity we call it 365 but because of the .25 extra days we add one day every fourth year.
because the solar year is approx. 365 1/4 days. so to keep the the year in balance and sync, you have to add one day to the solar calendar every four years.
if we stop having leap years starting today, then 480 yrs from now, summers would start in february, instead of june...LoLzzz
365 days and 6 hours is how long it takes the Earth to go once around the sun ... so every four years, we need an extra day.
These answers aren't completely correct -- It takes the earth slightly less than 365.25 days to go around the sun, so a Leap Year is *not* every 4 years. It occurs 97 times every 400 years... the next years divisible by 4 that will not be a leap year is the year 2100, 2200 and 2300 after that. The rule is, if a year is divisible by 100 but not by 400, then it is not a leap year.
The earth's rotation around the sun is not 365 days exactly. We loose a little time each year which amounts to a day every four years, so we add that day onto the month of February. If we didn't, our calendars would be way off.
Takes the earth 365.242199 years to orbit not just 365. This is also why years that are divisable by 400 such as divisible by 100 are not leap years, unless they are also evenly divisible by 400, in which case they are leap years.For example, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not. this is to compensate for the .002199.
