By Your Age

By Your Age is a small, focused web project that answers a single question: what had real people already done by your exact age, counted in days? Instead of comparing whole years, it cuts a precise line through each life, showing what was already accomplished above that line and what still lay ahead below it. The result is a personal, date-level view of achievement rather than a generic age chart.

The core interaction is simple. You enter your birthday, and the site counts your age in days, then places that same point on the timeline of each selected life. An age ladder displays every milestone from youngest to oldest on one shared scale, with your age marked as a marigold line. You can jump to any marker, switch between lives, or copy a comparison to share. Dates come from Wikidata and cited sources, and the site is explicit that it presents a selected sample of lives, not a forecast.

Privacy is handled deliberately: your birthday stays in the browser and is never sent, stored, or copied. That makes the tool safe for casual use without an account. The collection is curated rather than exhaustive, so it works best as a reflective prompt, not as a biographical reference or a motivational program.

It suits curious readers, history enthusiasts, and anyone who enjoys putting their own timeline in perspective. Use it with a specific birthday, explore a few different lives, and treat the comparisons as a lens for reflection rather than a benchmark to measure yourself against.
