A lens, not a prophecy
Life percentage calculator
of your horizon lived
– weeks lived · – weeks left
The Mac app keeps it on your desktop — moving one dot a week.
Reading the number kindly
A percentage compresses your whole timeline into one figure, which is exactly its power and its danger. Two readings are available. The anxious one: so much is gone. The useful one: look how much remains, and how visible it just became. At 30 years old on an 80-year horizon you are 37% through — which means nearly two-thirds of your weeks are still blank dots.
The horizon is an assumption, not a diagnosis — move it between 70 and 100 and watch the number shift; the point survives any setting. For the full picture behind the percentage, the life in weeks calculator draws every week, and the Mac app keeps the figure quietly current on your desktop.
Questions
What percentage of my life is over?
Enter your date of birth and a horizon (80 years by default): the tool shows the exact percentage lived and remaining. It is a lens, not a prophecy — the horizon is yours to move.
What percent of life is spent asleep?
Roughly a third, at 7–8 hours a night. Which makes the waking remainder — the dots still faint on your grid — worth seeing clearly.
Is this morbid?
People expect it to be, and then describe the opposite: the number makes this week feel scarce enough to spend on purpose. That is the entire philosophy of this site.
