The normal calendar has 365 days on it, but it takes the earth 1/4 day longer than that to travel all the way
around the sun in its orbit. So the earth is lagging a whole day behind the calendar every 4 years.
We make every 4th year 1 day longer, in order to let the earth catch up to the calendar.
If we didn't do that, then after 200 years, instead of March 21, the calendar would race ahead
all the way to May 10 before the first day of Spring came along.

∙ 9y agoBecause the Earth takes very nearly 3651/4 days to complete an orbit around the
sun, and that's the real length of the year. So how many squares should we
have on our calendar ? 365 isn't enough, and 366 is too much. We save up the
quarters until we have enough to make a whole day, and then we add the whole
day to the calendar one time.
If we didn't do anything about the quarters, then every century, the seasons
would start about 25 days later. If the longest day of the year was June 21
in the year when Columbus discovered America, then it would be around the
end of October by now. None of that is exactly, but you get the idea.

∙ 14y agoa complete year ( the time passes while earth complete its tour around sun) is 365 days, 6 hours, 49 minutes. but we have 365 days. the remaining 6 hours an additional day in every 4 years. 49 minutes and the minors corrects in every 400 year and 4000 years but doesn't matter cause average human life is 72 years.

∙ 14y agoThe Earth orbits the Sun every 365.256366 days. Since humans like to deal with whole numbers of days the extra day we add in a leap year accounts for the .25 of a day and brings us back into sync with the actual orbit.

What is the actual time your planet Earth takes to go around the sun?
the geological calender has only 365 days in a year and 366 in a leap year.the reason why there is an extra day in a leap year is it takes the earth 365.25 days to orbit once. so if you multiply 0.25 by 4 you would end up with one. this one is added as an extra day at the end of February after every four years.
How many days equal 16 years?

Why 28 days in Feb?
There are 28 days that exist in February except for every fourth year when there is a day added which is of course the February 29th. The reason being that each day is not exactly 24 hours rather there is a little bit of time that each day goes over the 24 hour period. To make up that time a 24 hour period is added to our calendar once every four years. Baby's that are born on the 29th of February are called leap year baby's. The year 2012 (and all years divisible by 4 but not 100 but 400) February has 29 days.
