What year were you born if you are 17?

Subtract 17 from 2026. The result is 2009. If your birthday is still coming up in 2026, your birth year is one year earlier: 2008.

Why the answer can be two different years

Age changes on a birthday, not on January 1. Without your birth month and day, both 2008 and 2009 are possible. Use the exact calculator to resolve the date precisely.
