  • Question 4
    1 / -0
    Leap year has ______ days.
    Solution
    Earth takes 365 $$^1/4$$ days to revolve around the sun. We consider a year consisting of only 365 days and ignore the last six hours for convenience. Six hours saved every year are added to make 24 hours or a day. These 24 hours are dded to the month of February and hence every fourth year is a leap year with 366 days.
