Enter a date of birth to get the exact age on any date.
Quick answer
To find exact age, count the whole years from the date of birth, then the remaining months, then the remaining days. Someone born on 1 January 2000 is 26 years, 9 months and 18 days old on 19 October 2026.

How it works
Age is counted in whole years, then remaining months, then remaining days. Change the 'age on' date to check eligibility on a specific date — useful for job applications, school admissions, visas, retirement plans and passport or ID applications that state an age limit on a cut-off date.
People born on 29 February have a birthday only in leap years. Most countries treat 1 March (or 28 February) as their legal birthday in other years; the calculator counts their age in whole years correctly either way.
