Age Calculator
Enter your date of birth to calculate your exact age in years, months and days, plus total months and total days lived.
How It Works
The calculator counts the full years, months and remaining days between your date of birth and the comparison date (defaulting to today), correctly handling different month lengths and leap years.
Example
Someone born on 12 April 2004, checked on 24 August 2025, is 21 Years, 4 Months, 12 Days old.
Frequently Asked Questions
- Can I calculate my age on a date other than today?
- Yes — use the 'Calculate Age On' field to pick any date, which is useful for figuring out your age at a specific event or eligibility date.
- Does the calculator account for leap years?
- Yes, the calculation is based on actual calendar dates, so leap years and varying month lengths are handled correctly.
- Why does it show total months and total days as well?
- Total months and total days are useful for eligibility checks or forms that ask for age in a single unit rather than years, months and days separately.
- What if my date of birth is after the comparison date?
- The calculator will show an error, since a date of birth cannot be after the date you're calculating age on.
