How to Calculate
The Age Calculator computes your international age and Korean age based on your date of birth.
International Age: Calculated based on whether your birthday has passed. If your birthday has not yet occurred this year, the age is (current year - birth year - 1); if it has passed, the age is (current year - birth year).
Korean Age: The birth year counts as age 1, and one year is added every January 1st. Calculated as (current year - birth year + 1).
