About this tool

Popularized by Tim Urban's 'The Tail End' and many stoic-writing traditions, the grid makes abstract time concrete: 90 years × 52 weeks = 4,680 boxes. This version renders it on canvas (fast, no uploads), marks lived weeks and this week, and labels milestones. It uses a 90-year horizon as a common planning frame — it is a perspective exercise, not a life-expectancy prediction for you personally.
