73 years is 3,796 weeks. By this point on the grid, most of the squares are filled in. The remaining ones are usually the most freely chosen — work obligations thin out, kids are grown, the question becomes what to do with the time, not how to fit it in.
The straight answer
73 years × 52 weeks = 3,796 weeks. If you'd rather count the extra leap days, the more precise figure is 3809.0 weeks — that's 73 × 365.25 days ÷ 7. For most planning, the round 3,796 is the number you want.

Mostly chosen weeks
3,796 weeks is, on an 80-year reference, 91% of a life. That leaves 9% — call it 374 weeks — as the remaining run.
The interesting math at this band isn't "how much have I used" — that's settled — it's "how much is genuinely mine to spend now." For most people, the post-50 weeks have a much higher proportion of "free" weeks than the front half did. Less work, fewer caregiving years, more weekends that aren't booked.
The trap, if there is one, is treating this stretch as a coda. It's not. It's the part of the grid where, for the first time, almost every square is a real decision.
