because there was still a quarter of a day left for the earth to make a complete revolution around the earth. by having a leap year every four years, those 4 quarter days left over (4 x 6 hours) makes an extra day which is included in a leap year. if there was no leap year.. eventually our winters would run into summers. (e.g winter will be in June as opposed to December in the northern hem.)

How many days and weeks are there in a year?
There are approximately 365.2425 days in a year in the Gregorian calender, and 7 days in a week. So, there are approximately 52.177 weeks per year. Rounding down gives us 52 weeks and 365 days in each year, except for leap years. Note that 52 weeks equals 364 days (52 x 7 = 364), which is not quite 1 year. The length of a year presently is closer to 365.2422 days so in the year 4000 they might adjust so that the astronomic equinoxes and solcistes realign.
What promblems arise from rounding a year to 365 days?
This question is back-to-front. It would be much better to ask, "What problems would arise if we didn't round the year to 365 days?" Problem 1. Earth's tilt relative to the sun would change a little each year and winter weather would come earlier and earlier. After about 600 years it would be snowing in mid-summer and the hottest days would be in the middle of winter. Problem 2. If every year were 365 .25 days as it really is, then the new year would start at six o'clock in the morning every fourth year and at midday each year after that and at 6pm too sometimes. The parties would be difficult to arrange and people wouldn't be too happy with the parties starting at 6am. Problem 3. Years would not begin on the first of January except once every thousand years or so.
