‘South Koreans will soon become a year or two younger, following an official change to the country’s age-counting system.
On Thursday, the country’s parliament, called the National Assembly, passed a set of bills requiring the use of the international age-counting system, where age is based on birth date.
South Korea currently uses three age-counting systems, but most citizens abide by the “Korean age,” where a person is 1 year old as soon as they are born, and gain one year on every New Year’s Day. And a baby born on Dec. 31 would be considered 2 years old the next day.
The change will go into effect this coming June….’
