In Weeks is a free interactive tool that visualizes your entire life as a grid of approximately 4,000 weeks. You enter your birthday and country, and it shows you how many weeks you've lived, how many remain based on life expectancy data, and lets you color weeks by life chapters like school, career, and travel.
