Your life in weeks
Every box is one week of your life. Enter your birthday to see how many weeks you have already lived, and how many are still ahead. Inspired by Tim Urban's "Your Life in Weeks."

What is the "life in weeks" idea?
Popularized by Tim Urban of Wait But Why, the life-in-weeks grid lays out a human life as roughly 4,000 boxes, one per week, about 52 a year. It is a blunt, oddly motivating way to see how finite time is and how much of it is still unwritten.
How many weeks are in a life?
At a life expectancy of 80 years, a life is about 4,160 weeks. This calculator counts the weeks between your birthday and today, then shows the rest of your expected weeks as empty boxes.
