Birth year by age

What Year Were You Born If You Are 15?

If you are 15 years old in 2026, you were born in 2010 or 2011, depending on whether your birthday has passed.

If you are 15 years old in 2026, your birth year is:

2010 or 2011

Born in 2011 if your birthday has already occurred this year; otherwise, born in 2010.

What year were you born if you are 15?

Subtract 15 from 2026. The result is 2011. If your birthday is still coming up in 2026, your birth year is one year earlier: 2010.

Why the answer can be two different years

Age changes on a birthday, not on January 1. Without your birth month and day, both 2010 and 2011 are possible. Use the exact calculator to resolve the date precisely.
