What year are leap year?

Answer 1

A leap year is needed because it actually takes the Earth 3651/4 days to orbit the Sun. Thus every 4 years you need to add in an extra day to a year or the calendar will slowly shift. Though a year is 365 days, it actually takes the earth 365 and a quarter days to revolve around the sun. To account for this extra time, every four years an extra day is added to the year to cover the four quarter days of the past four years. This extra day is February 29th.

Answer 2

Every fourth year is a leap year. 2010 is not a leap year. The next leap year will be in 2 years.

The last leap year was 2008, and the next leap year will be 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040....

Leap years are included to ensure the calendar stays roughly synchronised with the seasonal and astronomical years. As the astronomical year is not precisely a whole number of days adjustments need to be made periodically. We cannot change the astronomical year so the calendar is adjusted to fit.

Years that are divisible by 100 are not leap years unless they are also divisible by 400. Hence 2000 was a leap year. A leap year is a year divisible by four - in all cases but those in which it is divisible by 100, but not by 400. For example, the year 2008 was a leap year. The year 2000 was a leap year, because it is divisible by 4, 100, and 400. However, the year 2100 will not be a leap year, as, while it is divisible by 4, and by 100, it is not divisible by 400.

Answer 3

-- Every year that's evenly divisible by 4, but not the even 1,000s .

-- Same year as Summer Olympics and USA presidential elections.
