Life in Weeks Calculator
See a chosen lifespan as a grid of weeks: weeks lived, weeks remaining, and the share of that planning horizon already filled.
How It Works
Formula
Variables, symbols and units
- Whole days between the birth date and today
- The lifespan in years chosen as the planning horizon
Calculation method explained
The grid contains 52 squares for each year in the chosen planning lifespan. Whole days since the birth date are converted to completed weeks, then those squares are filled. The highlighted square marks the current week in the grid.
Frequently Asked Questions
Is this predicting lifespan?
No. The lifespan is a number you choose for planning and reflection; it is not a prediction about any person.
How is a week counted?
The calculator counts whole days from the birth date to today, divides by seven, and fills one square per completed week.
Is the birth date stored?
No. The calculation runs in your browser and does not save the date.
