Your life in weeks

One square is one week, one row is one year. Fill in your date of birth and the horizon you want to look through, and the grid is drawn here, in this tab.

An estimate you choose and can change at any time — never a prediction. Start from an average lifespan, from family longevity, or from an age that feels honest.

Your date of birth never leaves your browser. Nothing is sent to a server, nothing is stored, and no analytics event carries it.

An example life, until you draw your own.

Each square is one week

What the app adds

This page draws the picture once. Lifiary keeps it: you give each week a score from 0 to 100 and add a private note, so after a year the grid stops being a countdown and becomes a record of what those weeks were actually worth. Day reflections roll up into weeks, months and years, and the home-screen widget keeps the current one in sight.

Questions about the life calendar

What is a life calendar in weeks?

A grid in which one square is one week of a life and one row is one year, so 52 squares across. Laid out on a single screen, time stops being an abstract quantity: you can see the weeks behind you and, against the horizon you chose, the ones still ahead.

Where does the idea come from?

The grid was made recognisable by Tim Urban's essay Your Life in Weeks on Wait But Why. Oliver Burkeman's Four Thousand Weeks takes the same arithmetic — a long life is roughly four thousand weeks — and argues that finitude is the reason to choose what you spend them on. Both are modern readings of memento mori, the far older stoic practice of keeping mortality in view. Lifiary is independent of those authors and their publishers.

How do I choose the horizon?

You choose it, and nothing here computes it for you. The 85 years this page starts from is a starting point, not a forecast about you. Take an average lifespan where you live, family longevity, or simply an age that feels honest — then change the number whenever you like and the grid is redrawn.

Where does my date of birth go?

Nowhere. The whole calculation and the drawing happen in your browser, the date is never sent to a server and never stored, and no analytics event carries it — this page sends at most an ordinary page view.
