A day is one revolution on the Earths Axis, which equals day and night, one day- the total of those occurance in the time span of one Revolution around the sun, its near 365, plus a few minutes that accumulates to an extra day. Leap year.
The Myans had this figured out long before the Greeks or Europeans and have a Calendar that predates modern history.

Gotta go with Sleepless here. Millenia ago, calendars were primarily for predicting harvest seasons. They simply figured out how many days it takes to go through the cycle of the seasons (don't forget, our ancestors knew a lot about sun positions, etc.; they could tell whether it was October 10th or October 11th just by the position of the sun in the sky - powerful stuff, that). 365 plus change was the answer, right? After a few thousand years, even this sytems began to go out of whack and adjustments were made and - long story very short - our modern calendar of 12 months/7 day weeks, plus that leap-year things every four years came about.

They divided up the time it took for the earth to make a complete circle around the sun..and it's actually a little more than 365 days, and that's why we have leap years...
