Life Weeks
Enter a birth date and lifespan to see an approximate life-in-weeks grid in your browser.
This is an approximate view using fixed 52-week years (364 days per year); it is not a prediction of lifespan.
A QUICK WALKTHROUGH
How to use this tool
- Enter your birth date and an illustrative lifespan.
- Choose whether to color life stages, then show the grid.
- Review elapsed weeks, remaining weeks, age, and the approximate percentage.
A visual estimate
Each row represents one fixed 52-week year. The filled cells show weeks elapsed from the date you enter; remaining cells are an illustrative remainder.
Private by design
The calculation runs locally in your browser. The date and lifespan are not saved or sent to a server.
GOOD TO KNOW
Common questions
Is this a lifespan prediction?
No. It is a personal visualization using the lifespan value you provide.
Why 52 weeks per year?
A fixed 52-week year keeps the grid consistent and easy to scan; calendar years vary slightly.
Does the tool store my birth date?
No. It stays in the page while you use it and is not uploaded.
