South Korea is changing the way it calculates a person's age.
Under a new law that takes effect Wednesday, South Korea is adopting the international method that uses a person's actual date of birth to determine their age.
Under its traditional method, South Koreans are considered to be one year old at birth, including their months in the womb, and become a year older every January 1 regardless of their actual date of birth.
The new law that takes effect Wednesday means all South Koreans will officially become a year or two younger.
Officials say a separate method of calculation that uses the date a person is born and then adds a year each January 1 will remain in effect for compulsory military service, education and the legal drinking age.
