Definition: Century

A century is a period of 100 years, which can have either 24 or 25 leap years, depends on whether the year xx00 is a leap year or not.

We assume there are 25 leap year days in a typical century. A non-leap year of 365 days would have 86,400 * 365 = 31,536,000 seconds in it. Adding another 25 days adds 2,160,000 seconds, so there are a total of 3,155,760,000 seconds in a century that has 25 leap years.
