Your life in weeks

It’s a grid with one dot for every week of a human life. At 80 years that’s 4,160 weeks. Filling in the weeks you’ve already lived shows, at a glance, how much has passed and how much may be left.

The idea was popularized by Tim Urban’s 2014 “Your Life in Weeks” post on Wait But Why, and Oliver Burkeman’s book Four Thousand Weeks (2021) takes its title from the same arithmetic.

Wait But Why: Your Life in Weeks

Thinking about mortality on purpose is very old practice. The Stoics called it memento mori, “remember you will die”, and used it to focus on what mattered rather than to frighten themselves.

Psychology research points the same way. When people see their time as limited they tend to put more weight on close relationships and meaningful goals (Laura Carstensen’s socioemotional selectivity theory). The aim is perspective, not dread.

If you haven’t thought about death often the first look can be overbearing. Personally, I’ve found that time starts to move a lot slower as you more frequently acknowledge the length of our lifespans. You’ve lived more than you think and you have more to live.

It can’t answer that for you, but it can help you notice things. Which past weeks you still remember and why, and who you’d want around for the next fifty-two. Purpose is often found in those patterns rather than in one big answer.

If the feeling is heavy or won’t lift, a doctor, therapist or someone you trust is a better place to start than any website. You don’t have to work it out alone.

They’re estimates. Survival odds come from the World Health Organization’s global life table (2023), the time-with-parents figures assume parents 25 years older and use Pew Research Center’s 2024 survey for how often adults see them, and the population figures come from Our World in Data and the UN. Your own life will differ and nothing is certain.
