How it works

A whole life,
one week at a time

4,000 weeks

The round number for a life of about 77 years, from Oliver Burkeman's book Four Thousand Weeks. The current life expectancy of an average American is 79 years.

One square per week

The grid is 50 squares across and 80 down: exactly 4,000. The numbers down the side mark the row where you reach each age. The filled squares are behind you, and the pulsing one is this week.

The weeks that are open

The weeks ahead with sleep, work, and upkeep taken out: 8 hours of sleep, a 40-hour week for 48 weeks a year until 65, and 3 hours a day of meals and chores.

Questions

A few things
worth asking

Is my birthday saved anywhere?

No. The sums run in your browser and your birthday is never sent to optml or anyone else.

Why 4,000 weeks?

We take this number from Oliver Burkeman's book Four Thousand Weeks. Life expectancy is an average that depends on where you live, your sex, and the age you have already reached. The time with your parents calculator uses life tables, if you want an estimate more tailored to you.

I am older than 4,000 weeks. Does it still work?

Yes. The grid fills completely and the page tells you how many weeks you have lived.
