Question

Why does the month of February have 29 days, after every four years? Explain.

 
Answer
  • The month of February has 29 days, after every 4 years because the earth completes one revolution in 365 days and about 6 hours. We consider 365 days in a year. The remaining 6 hours are added over a period of 4 years till they become 24 hours or one day. This extra day is added to the month of February every four years to make it a month of 29 days instead of 28 days.
