Age Calculator
Calculate exact age in years, months and days from date of birth.
How it works
We calculate the exact difference between your date of birth and the reference date (today, unless you choose another date), broken down into full years, months and days, accounting for varying month lengths and leap years.
Example
Someone born on 15 August 2000, calculated as of 14 September 2026, is 26 years, 0 months and 30 days old.
Frequently asked questions

Yes, the calculation is based on actual calendar dates, so leap years are automatically handled correctly.
Can I calculate age as of a future or past date?
Yes, use the 'Calculate age as of' field to pick any date, not just today.
