Life in weeks calculator
An 80-year life is about 4,175 weeks. Enter your birth date and see yours — every week you've lived, every week you have left, one honest grid.
– weeks lived · – weeks left · –
Nothing leaves your browser — your date is yours.
Print it. Hang it.
Or let it live on your desk.
The chart you just made is a snapshot — true today, stale tomorrow. Print it as a poster if you like paper. If you'd rather it stayed true, the Mac app repaints it on your wallpaper every midnight: same grid, always current, $19 once.
Questions
How does the life in weeks calculator work?
Enter your date of birth and a lifespan (80 years by default). Every week from birth to that horizon becomes one circle — filled if you have lived it, faint if it is still ahead, ringed if it is this week. The math runs in your browser; your date never leaves your device.
Can I print my life in weeks chart or save it as a PDF?
Yes — generate your calendar, then use the Print / PDF button (or your browser's print dialog). The page prints just the chart, clean black on white, ready for a wall.
Can I download it as a wallpaper?
Yes, in one click — light or dark, sized for your screen, a 4K monitor, or a phone. For a wallpaper that re-draws itself every midnight, see the Mac app.
Where does the idea come from?
Tim Urban's essay "Your Life in Weeks" on Wait But Why popularised drawing a human life as ~4,000 weekly boxes, and Oliver Burkeman's book Four Thousand Weeks built a philosophy of time around the same number.
