2023 Korean Age Unification — What Changed?
Since June 28, 2023, Korea officially uses international age (만나이) in all civil law and government documents. In everyday conversation, Koreans still commonly use the traditional Korean age (세는나이). Some laws, like military conscription, still use year age (연나이 = current year − birth year).
