About the Age Calculator
The age calculator turns a date of birth into your exact age in years, months and days, plus the total number of days and hours lived. Handy for birthdays, paperwork, contracts, or settling arguments about who is older.
Everything runs in your browser. No inputs are uploaded, logged or stored on our servers.
How it works
- Enter the date of birth.
- Optionally enter a target date (defaults to today).
- Read the breakdown in years, months, days and total days.
What you'll learn
- Your precise age, not just the rounded year.
- How many days you have been alive.
- How leap years affect day counts.
FAQs
- Can I calculate age at a future date?
- Yes. Change the target date to any future day to see how old you will be then.
- Does it handle leap years?
- Yes. Day counts use the real calendar, including February 29s.
