How many hours are in a century?

Assuming there are 24 leap years in a century, as there will be in the centuries 2001-2100, 2101-2200, and 2201-2300, one century is equal to (76 x 24 x 365) + (24 x 24 x 366) = 876576 hours.

Assuming there are 25 leap years in a century, as there were in the century 1901-2000, one century is equal to (75 x 24 x 365) + (25 x 24 x 366) = 876600 hours.
