Why weeks?
A year feels long and a day feels small, but a week is the unit most of our plans are made in. Seeing every week of a life on one screen makes it easier to ask what matters in the ones ahead. The idea was popularised by Tim Urban’s “Your Life in Weeks” essay.
Frequently asked questions
Is my birthday stored?
Only in your browser, so the page remembers it next time. It isn’t sent anywhere.
How are heartbeats estimated?
Using an average resting heart rate of 75 beats per minute for every minute you’ve lived. Real numbers vary a lot.
What life expectancy should I use?
It depends on where you live and your health. The setting is just for perspective; try a few values.
