What is a Leap Year?

Note: This video answers the question I raised here, through “Actually, the moment of Earth’s revolution (the spin around the Sun) lasts 365 days, 6 hours, 9 minutes and 9 seconds. The reason why terrans gave the calendaristic year a round number is of practical nature. Still, from the same practical reasons, because of those six additional hours, the day of 29 february is added. I don’t know where the 9 minutes and 9 seconds go….: every 100 years, the first year of the new century (ex: 1800, 1900, 2000, 2100), despite being a leap year, doesn’t receive an additional day in February (the 29th day).
