Leap Year Explained Why We Add An Extra Day A leap year is a year with an extra day added to keep the calendar year synchronized with the astronomical or seasonal year. because earth’s orbit around the sun takes approximately 365.2425 days – not a perfect 365 days – we add a day every four years to compensate for this discrepancy. Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400.
Leap Year How Does It Work Clearias What is a leap year? the short answer: it takes approximately 365.25 days for earth to orbit the sun — a solar year. we usually round the days in a calendar year to 365. to make up for the missing partial day, we add one day to our calendar approximately every four years. that is a leap year. Leap year, year containing some intercalary period, especially a gregorian year having a 29th day of february instead of the standard 28 days. the astronomical year, the time taken for the earth to complete its orbit around the sun, is about 365.242 days, or, to a first approximation, 365.25 days.

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! so another rule says every 400 years is a leap year again. What is a leap year? this calendar oddity occurs once every four years—and helps keep us in sync with the seasons. if your birthday is february 29, you can celebrate your actual birthdate only. Every four years we have a 29 february – apart from those that fall at the turn of a century, unless the year is divisible by 400. this is the messy story of how leap years work.
