The rotational period of the earth is 23.9345 hours or .99727 days. If you take 
the left over time in a day and multiply it times 365.256 you get almost exacly 
24 hours. that means that the earth has rotated 24hours that aren't included in 
the 365 days. another way to think about it is to visualize the earth and the 
sun. If the earth rotated 23.9345 hours and moved in its rotation, the sun 
would not be at noon but would be roughly 3min 56 sec from noon. if we take the 
3 min 56 sec extra the earth has to spin and multiply it by 365.256 days we 
find that the earth rotated one complete extra time. therefore a day is not 
equal to a rotation but 1 and (1/365.256) rotations. My science teacher doesn't 
believe me and i've done my reasearch so could you please help me out?
