A leap year is cased To make up for the missing partial day, we add one day to our calendar approximately every four years.

Answer:

  • In a leap year, we add an extra day on 29 February to our calendar of 365 days. What goes around: The reason we have February 29 every four years is because of two different time cycles involved with the rotation of the Earth. Leap years happen every four years, except if the year is a multiple of 100
