Age by Birth Year
Find your age today by browsing your decade or selecting your exact birth year. If you only know the year (not the birthday), ages are shown as a range.

How age-by-year ranges work
If you only know a birth year (not the full birthday), your exact age depends on whether your birthday has happened yet in the current year. That’s why many charts show a range like 30–31.
- Lower number: your birthday hasn’t happened yet this year.
- Higher number: your birthday already happened this year.
For exact results (years, months, days), use a calculator that includes your full date of birth.

If only the birth year is known, the exact age depends on whether your birthday has already occurred this year.
