every saturday of your life, in a grid. the grey ones are gone. you can't have them back. sorry about that.
Here is a fun exercise. Take the number 4,160. That is roughly how many Saturdays you get in an 80-year life. Now subtract your age times 52. That is how many you have already used. On what? Mostly sleeping, grocery shopping, doing laundry, and scrolling through your phone while telling yourself you will do something fun later. Later never came. Later is a myth.
We take your age, multiply by 52 weeks per year, and subtract from the total weekends in your expected lifespan. Then we break down your remaining weekends into categories: truly free time, sleeping in, working weekends, and chores. The result is a grid where every dot is one Saturday of your life. The grey ones are gone. The colored ones are what is left. It is less than you think.
At age 25, about 2,860. At 35, about 2,340. At 45, about 1,820. At 55, about 1,300. At 65, about 780. If those numbers feel small, that is because they are. A human life has fewer Saturdays than a typical smartphone has apps.
Tim Urban's famous Your Life in Weeks essay showed that seeing your entire life as a grid of boxes is profoundly motivating. We took that concept and made it worse. Instead of weeks, we use weekends, the only time most people feel alive. And instead of motivating you, we also tell you how many of those weekends you will spend on laundry. You are welcome.
We are a calculator, not a life coach. But statistically, you will spend 15% sleeping, 12% on chores, 8% working, and most of the rest on things you will not remember in 5 years. The roughly 30% of truly free weekends is all you actually control. Use them on whatever makes you feel something. Or don't. We are just math.
