A year's orbit around the Sun takes approximately 365 days, 5 hours, 48 minutes, and 45 seconds. Every four years, time is accumulated to a total of 24 hours, and one day is added to keep the calendar day count consistent with the sun's position and seasonal changes. If the experiment is not carried out, the next 700 years could see summer in April instead of July.
This extra day is known as Leap Day, and the year with 366 days is called Leap Year.
