How does a century consist of 24 leap year?

1 century consists of 100 years. Leap year occurs every 4 years. So, there will be 100 : 4 = 25 leap years in a century. But, a century which its last year (xx00) is not divisible by 400 and only by 100 will only have 24 leap years. In 400 years, there will be 97 leap years (25 + 24 + 24 + 24). read more

Shortest answer: A year is a leap year if it is divisible by 4, but century years are not leap years unless they are divisible by 400. So, the years 1700, 1800, and 1900 were not leap years, but theyear 2000 was, which is why in a given 100 years, there are 24 leap years and 76 ordinary years. read more

Century years (divisible by 100) that are not divisible by 400 are common years (with 365 days) and not leap years. For example, the years 1600, 2000, and 2400 are century leap years since those numbers are divisible by 400, while 1700, 1800, 1900, 2100, 2200, and 2300 are common years despite being divisible by 4. read more
