When the Earth revolves around the sun, it completes one revolution every 23.9 hours, and it takes 365.25 days to complete one trip around the sun. This extra quarter of the day challenges the solar calendar system that counts one year as 365 days. So to keep the annual calendar consistent with the Earth’s journey around the sun, one day is added every four years and the year to which the day is added is called a “leap year.”
