Frequently asked questions
Is this calculator accurate?
Yes. It accounts for leap years, varying month lengths, and (when provided) your time of birth.
Do you store my data?
No. All calculations happen in your browser. Nothing is sent to a server.
Can I see my age on a future date?
Yes — use the "Calculate age as of" field to project your age on any future date.
How are the fun facts calculated?
They use rough averages: ~70 heartbeats/min, ~16 breaths/min, ~8h sleep/day, 3 meals/day, etc. They're approximations for fun, not medical figures.
