What year were you born if you are 1?
Subtract 1 from 2026. The result is 2025. If your birthday is still coming up in 2026, your birth year is one year earlier: 2024.
Why the answer can be two different years
Age changes on a birthday, not on January 1. Without your birth month and day, both 2024 and 2025 are possible. Use the exact calculator to resolve the date precisely.
