Answer:
A century is 100 years
If a century year is divisible by 400, then that year is a century leap year. If a century year is just divisible by 4 & 100, but not 400, that year is not a leap year. The original years that are divisible by 4 are common leap years. If you were born on a leap year & if you were born on February 29, your actual birthday on a common year is March 1, but some people decided to celebrate a person birthday on February 28 if that year isn’t a leap year.

Since every 4 years is a leap year & every 400 years is a century leap year, 1 full year is 365.25 days; therefore, 4 years is equivalent to 1,461 days.
If a century year is divisible by 400, a century has 25 leap years; therefore, an original century has 24 leap years
