5,200 weeks is exactly 100 years — a century, 100 × 52. So "how many years is 5,200 weeks" and "how many weeks in 100 years" are the same question from opposite ends. A century is longer than almost anyone lives: most lives fill 75–85 of those 100 rows.
The straight answer
5,200 weeks ÷ 52 = 100 years. Counting the extra leap days (52.18 weeks per year), the more precise figure is 99.7 years — about 99 years and 8 months. For most purposes the round 100.0 years is the number you want.
