 What is a Leap year ? Generally  we have 28 days in the month of February and overall 365 days in a year. But a leap year have 29 days in the month of February and overall 366 days in a year. For every four years we get a leap year. Conditions to be a leap Year. Year divisible by 4 is a leap year until it is not divisible by 100 (century year{year ends with 00} is not a leap year until it is divisible by 400, if it is divisible by 400 then it is a leap year. Explanation :  For a non century year  if year divisible by 4 then it is a leap year. For a non century year  if year not divisible by 4 then it is not a leap year. If year is a century year then it is not a leap year. Century year is said to be a leap year if it is divisible by 400 . Input : enter a year 2400 Output :  2400 is a leap year  Program to find leap Year or not in Python #program to say leap year or not year=int(input("enter a year ")) if year%4==0: if year%100==0: if year%400==0: pri
