As of just this week South Koreans are now a year or two younger! Now this isn’t literal, if you and your Korean friend were both born in 2000 they are not suddenly younger than you. For the longest time Koreans had a separate age system that added a year to a person’s age. Well not anymore!
For a while now many Koreans and politicians have wanted to put an end to the Korean age system. The president, Yoon Suk-yeol, has said before the current age system has been a drain on resources. And a recent 2022 survey suggested “86% of South Koreans said they would adopt the international system”. So better late than never the change starts now!
