By mathematical computation, at 60 seconds per minute, 60 minutes per hour, 24 hours per day, and 365.25 days per year, the answer would be : 31,557,600 seconds per year, 3,155,760,000 per century, and 9,467,280,000 in three centuries. However, by the more precise definition (which requires adjustment of the calendar with "leap seconds" and omitted "leap days"), there are 31556925.9747 seconds in a standard SI year, which equals 3,155,692,597 (and a fraction) per century and 9,467,077,792(and a fraction) in three centuries.
