Life in Weeks Calculator
Inspired by the famous 'life in weeks' visualization, this calculator shows your life in numbers: weeks lived, weeks remaining, and what percentage of your expected life is already behind you.
About this calculator
See how many weeks of your life you've already lived and how many you have statistically left, based on your birthdate and a target life expectancy.
Frequently Asked Questions
How is this calculated?
We multiply your age and life expectancy by 52.1775 (the average number of weeks per year, accounting for leap years) to get total weeks, then subtract weeks lived from the total.
Is this meant to predict when I'll die?
No. This is a fun, reflective tool based on population-average life expectancy, not a personal or medical prediction.
Why do people find this visualization powerful?
Seeing your life as a finite number of weeks rather than an abstract span of years is a popular way to reflect on time and priorities, popularized by writer Tim Urban's 'Life in Weeks' post.
