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.

Frequently asked questions
How accurate is the days-alive calculation?
It is exact to the second using your birth date and current local time. Leap years are counted automatically (1 extra day every 4 years, with century-year exceptions). The calculator uses the Gregorian calendar — the same one your birth certificate uses.
Are derived stats like heartbeats and breaths accurate?
They are estimates using population averages: ~80,000 heartbeats and ~22,000 breaths per day for a healthy adult. Individual numbers vary based on age, fitness, and activity level. The numbers are mathematically consistent with your day count but should be treated as ballpark figures, not measurements.
Why does seeing days-alive feel different from seeing years?
Years compress time so much that they hide the actual scale of life. A 30-year-old has lived nearly 11,000 days — a number large enough to feel weighty. The Stoic tradition (Seneca, Marcus Aurelius) explicitly used day-counting to make finite time visible and drive better decisions. Modern "memento mori" calendars work the same way.
Is my birthday data stored anywhere?
No. All calculations happen in your browser. Your birth date is never sent to a server, never logged, and never stored. You can verify this by checking the network panel in your browser's developer tools — no requests fire when you compute the result.
