2,500 weeks is 48.1 years — about 47 years and 11 months, or roughly 60% of an average life. That's most of an adult life: the working years, the raising-people years, the stretch where the grid turns from a budget into an audit.
The straight answer
2,500 weeks ÷ 52 = 48.1 years. Counting the extra leap days (52.18 weeks per year), the more precise figure is 47.9 years — about 47 years and 11 months. For most purposes the round 48.1 years is the number you want.

Most of an adult life
2,500 weeks (47 years and 11 months) sounds like a lot until you net out the parts that aren't free. Roughly a third goes to sleep; a large share of the rest to work. The weeks that are genuinely yours to spend are a fraction of the gross number — which is exactly the argument Four Thousand Weeks makes.
At 60% of an 80-year life, a count this size is the part of the grid where what you've already spent is settled and what's left is the live question.
