Frequently Asked Questions

How are these numbers calculated?
We count the days between your birth date and today, then derive the rest: hours, an estimated heartbeat count (~75 beats per minute), breaths (~16 per minute), trips around the Sun (one per ~365.25 days), full moons (one per ~29.5 days), and time asleep (about a third of life).
Are the heartbeat and breath counts exact?
No — they are fun approximations based on average resting rates. Real heart and breathing rates vary a lot by age, fitness, and activity, so treat these as ballpark figures, not medical data.
Is my date of birth sent anywhere?
No. Everything is calculated in your browser, and your last result is stored only on your device (localStorage). Nothing is sent to a server.
