Frequently asked questions
How do I calculate my exact age from my date of birth?
Enter your date of birth in the calculator above and click Calculate My Age. You will instantly see your precise age in years, months, days, hours, minutes and seconds. For second-level precision, add your time of birth too.
Is this age calculator accurate?
Yes. It accounts for leap years, varying month lengths, and — when provided — your exact time of birth, giving you second-level precision.
Can I find out how many days old I am?
Yes. After calculating your age, the results panel shows your total age in days, weeks, hours, minutes and seconds — not just years.
Do you store my date of birth or personal data?
No. All calculations happen entirely in your browser. Nothing is sent to a server and no data is stored or shared.
Can I calculate my age on a future date?
Yes. Use the optional Calculate age as of field to project how old you will be on any future date.
How are the fun life facts calculated?
They use widely accepted averages: approximately 70 heartbeats per minute, 16 breaths per minute, 8 hours of sleep per day, and 3 meals per day. These are fun estimates, not medical figures.
