Correct Answer - Option 3 : 29 days
Earth takes 365 days and 6 hours (approx) to complete one revolution around the sun. The 6 extra hour taken by earth each year contributes to one extra day of a leap year and that extra day is added to the month of February.
Hence, February has 29 days in a leap year.
- February has 29 days in a leap year. Leap year comes after every 4 years.
- Leap year is the year in which one additional day is added to February and makes 366 days in a year.
- Gregorian calendar is the standard calendar in most of the world, most years that are multiples of 4 are leap years.
- In each leap year, the month of February has 29 days instead of 28.
- There are 12 months in a year like January contains 31 days, February 28 days but in a leap year it contains 29 days, March contains 31 days, April of 30 days, May of 31 days, June contains 30 days, July 31, and August also 31 days, September of 30 days, October has 31 days, November has 30 days and December of 31 days.
- That means 7 months of 31 days, 4 months or 30 days, and one of 28 or 29 days.
