Every four years in the Gregorian calendar, an extra day is added to the calendar in order to synchronize it with the solar year. It takes the earth a little bit less than 365 ¼ days (365.242 days) to orbit the Sun (solar year). For this reason, the full day is only added once every four years. In the Julian calendar, there is still an 11-minute, 14-second discrepancy each year.
