A sidereal year (from Latin sidus "asterism, star") is the time taken by the Earth to orbit the Sun once with respect to the fixed stars. Hence it is also the time taken for the Sun to return to the same position with respect to the fixed stars after apparently travelling once around the ecliptic. It equals 365.25636 SI days for the J2000.0 epoch.
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.
