How it works
The calculator takes your birth date and current time, computes the elapsed seconds, and converts to whichever unit you asked for. Year-progress uses the start of the current year as the baseline; life-progress uses an assumed lifespan.
Life-stats calculators became viral around 2018 with the rise of "memento mori" calendar apps. The concept traces back to Stoic philosophy (Seneca's On the Shortness of Life, ~49 CE) — making finite time visible to drive better daily decisions.
Who uses the life in weeks stat
Productivity readers, life-design coaches, students writing personal essays, and anyone wanting a Stoic-style reminder of finite time.

Frequently asked questions
What does the life-in-weeks grid show?
Each dot represents one week of your life. A typical 80-year lifespan is 4,160 weeks — small enough to fit on a single screen. Weeks already lived are filled in; remaining weeks are empty. The visualization comes from Tim Urban's "Your Life in Weeks" essay (Wait But Why, 2014).
Why visualize life as weeks instead of years?
Years are too coarse — a 30-year-old looks like they have 50 more years left, which feels infinite. Weeks make the same lifespan look like a finite, countable object. Research on temporal-perception (Hershfield) shows concrete time visualizations drive longer-term decision-making more effectively than abstract numbers.
Is the grid based on a specific life expectancy?
It uses 80 years as the default — close to the WHO global average for developed countries (USA: ~78, Japan: ~84, EU average: ~81). You can adjust the assumption in the input. The exact number is less important than the visualization — the point is to make remaining time visible.
Is my birthday data stored?
No. All visualization happens in your browser. The birth date never leaves your device — no server request fires when you generate the grid. Refresh the page and you start fresh.
