Life in Weeks Calculator

Enter your birthday to see your life as a grid: every square is one week, every row is one year.

-weeks lived
-days lived
-weeks left
-of life used

Red squares are weeks already lived, the outlined square is this week, grey squares are weeks still ahead.

How it works

We count the full weeks between your birthday and today, then compare with your chosen lifespan (90 years is 4,680 weeks). Seeing it as a finite number of squares is a popular way to put time in perspective. Nothing is uploaded; your birthday stays in your browser and only goes into the link if you copy it.
