Why do we have leap years?

The most common explanation is that we have these years to keep the calendar in line with the seasons. Although we learned in school that it takes the Earth 365 days to revolve around the Sun, the rotation actually takes about 365.25 days. Adding an extra day every four years will keep the balance.

Without leap years, 100 years from now, “summer will be in November or December,” explains Robert S. Washington III, a graduate student at NASA’s Goddard Space Flight Center in Maryland.
