Every 4th year we add an extra day (the 29th of February), which makes 365.25 days a year. This is fairly close, but is wrong by about 1 day every 100 years. So every 100 years we don't have a leap year, and that gets us 365.24 days per year (1 day less in 100 year = -0.01 days per year). Closer, but still not accurate enough!
Leap days are important because they help our calendar match up with the same seasons every year. Human-made calendars generally have 365 days; the solar, or tropical, year that influences seasons is about 365.2422 days long. (A solar year is how long it takes the Earth to revolve around the sun .)

If a year is divisible by both 4 and 100, then it might not be a leap year, and you will have to perform 1 more calculation to check.

27 de feb. de 2020 · By adding a leap day every four years, we actually make the calendar longer by over 44 minutes. Over time, these extra 44+ minutes would also cause the seasons to drift in our calendar. For this reason, not every four years is a leap year. The rule is that if the year is divisible by 100 and not divisible by 400, leap year is skipped.
3 de may. de 2024 · leap year, year containing some intercalary period, especially a Gregorian year having a 29th day of February instead of the standard 28 days.
