Where the idea comes from
The life calendar, one square per week, was popularised by Tim Urban's essay Your Life in Weeks on Wait But Why. It works because weeks are a unit you can feel: you remember last week, and you can see how few summers are left in a row of squares.
How many of your weeks go to screens
At the adult average of 6:38 a day, screens take about 28% of all your hours. The screen time calculator turns your own number into years, and Timecard measures it for real on your Mac.
