Calculate your traditional East Asian age (used historically in Korea and China).
In traditional East Asian age reckoning (historically used in China, Korea, Japan, and Vietnam), individuals are considered one year old at birth, and their age increases by one year on New Year's Day, rather than on their exact birthday.
While officially phased out in South Korea recently, the "Korean Age" system is still deeply embedded in social culture. Our Traditional Age Calculator uses the standard formula: (Current Year - Birth Year) + 1 to instantly determine your traditional age compared to your standard international age.
