While some are expected to keep using the old system, 86% say they will adopt the international system in their everyday lives
All South Koreans have instantly become a year or two younger, as the country ditched its traditional – and increasingly unpopular – system for counting someone’s age and replaced it with the internationally accepted method.
Under the previous system, the country’s citizens are deemed to be a year old when they are born, and a year is added every 1 January. The unusual custom meant that a baby born on New Year’s Eve would become two years old as soon as the clock strikes midnight.
