31 years is 1,612 weeks. Roughly the working life of a person who keeps the same kind of job their whole career, or about half of a long human life. It's the span where the grid starts to feel less like a budget and more like an audit.
The straight answer
31 years × 52 weeks = 1,612 weeks. If you'd rather count the extra leap days, the more precise figure is 1617.5 weeks — that's 31 × 365.25 days ÷ 7. For most planning, the round 1,612 is the number you want.
What 31 years looks like

What 31 years actually contains
1,612 weeks sounds like a lot. The honest accounting is smaller. About a third of those weeks (≈ 537) you'll spend asleep. Another 576-ish, conservatively, will go to work. What's left — the "yours, awake, free, decision-making" weeks — is somewhere closer to 403 to 564.
That's the number worth sitting with. It's the budget you actually get to spend on the things you say matter to you.
31 years is also exactly 39% of an 80-year life. If you're inside this band right now, the back half of the grid is the bigger story than the front half — and it's the part you can still decide what to do with.
