why do we need leap years ? Since it takes Earth approximately 365 1/4 days to orbit the sun, an extra day's worth of time accumulates every four years. In a leap year, February receives an extra day to compensate for the difference between the astronomical year and the calendar year. If no adjustment were made, the calendar and the seasons would drift apart by 24 days every 100 years. the plan of adding a day every four years was devised by the Egyptians . the Romans created a standard day February live February 29, in 46 b.c. adding one day per 4 years didn't perfectly correct the problem, however, because Earth orbit in 11 minutes and 14 seconds less than 365 1/4 days , A correction, established in 1582 , adds a leap day only to century year divisible by 400. thus 2000, was a leap year, but 2100 ,2200 and 2300 will not be.
