Why calculate your free time?
Feel like you're always running out of time? You're not alone. Time gets diluted in sleep, work, commute, chores and — above all — screens. This simulator isn't here to stress you out. It's here for a positive wake-up call: see, in years and in weeks, the time you actually own.
How the calculation works
We start from your total remaining lifetime in hours (years left × 365.25 × 24), then subtract:
- Sleep: weighted average between weekday and weekend nights.
- Work and commute: counted until your retirement age, then zeroed out.
- Logistics: meals, cleaning, groceries, showers, paperwork.
- Screens: deducted last, directly from your positive free time.
What is "life in weeks"?
Each square on the grid is one week of your life. A life of 85 years = 4,420 weeks. Seeing the proportion of "free" squares vs. obligations changes the scale. Instead of "no time tonight", you think in years.
3 reflexes to reclaim time
- Cut notifications. 30 min less screen time daily = almost 1 year of free time recovered over 40 years.
- Batch logistics. Meal prep, auto-groceries, bulk laundry: 3h a week, easy.
- Work from home. 2 commute-free days = 5 extra weeks of holidays per year.
FAQ
What life expectancy should I use?
In France it's about 85 for women and 80 for men. The default is 85 but you can adjust the slider.
Why deduct screen time?
Because it's the sneakiest time thief. We rarely see it as an obligation, yet it often eats 3–5 hours a day. It's deducted from raw free time to get "quality" free time.
What are the "big projects"?
About 1,000 focused hours for a big life project: writing a novel, seriously learning an instrument, building a shed, launching a side project.
Is work counted for life?
No. The simulator stops counting work hours (and commute) at the retirement age you set. After that, the time flips into free time.
Is my data stored?
No. Everything runs in your browser. Nothing is sent to the server, no account, no tracking cookie.
Why does my age change the result so much?
Because remaining time directly depends on the gap between your current age and life expectancy. At 30, you have ~55 years left; at 60, only ~25. Obligations stay proportional, so your margin shrinks.
