Korean Age Calculator

Enter your birth date to get your international (만) age and year age, following Korea's unified-age law (effective June 2023).

The two ages

• International (만) age — this year − birth year, minus 1 if your birthday hasn't passed yet. This is the legal and everyday age in Korea now.
• Year age — simply this year − birth year. Used by a few laws (military service, youth-protection).
