International vs. East-Asian age
This tool uses international age: you are 0 at birth and gain a year on each birthday. The traditional "Korean age" counted you as 1 at birth and added a year every 1 January. South Korea standardized on international age for legal and administrative use on 28 June 2023. Japanese and Chinese traditional counting systems also differ; this calculator always uses the internationally standard method.
