35 years is 1,820 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
35 years × 52 weeks = 1,820 weeks. If you'd rather count the extra leap days, the more precise figure is 1826.3 weeks — that's 35 × 365.25 days ÷ 7. For most planning, the round 1,820 is the number you want.
What 35 years looks like
Each row is one year. Each square is one week. 35 rows × 52 columns = 1,820 squares.

What 35 years actually contains
1,820 weeks sounds like a lot. The honest accounting is smaller. About a third of those weeks (≈ 607) you'll spend asleep. Another 650-ish, conservatively, will go to work. What's left — the "yours, awake, free, decision-making" weeks — is somewhere closer to 455 to 637.
That's the number worth sitting with. It's the budget you actually get to spend on the things you say matter to you.
35 years is also exactly 44% 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.
