South Koreans have not become younger in terms of their biological age. However, on June 28, 2023, South Korea began using the international age counting system, which means that everyone in the country is now a year or two younger than they were under the old system.

The old system, which had been in place for centuries, counted a person as one year old at birth and added another year on January 1st, regardless of their actual birthday. This meant that a baby born on New Year's Eve would become two years old the next day.

The new system, which is used by most other countries in the world, counts a person's age from their date of birth. This means that a baby born on New Year's Eve will still be considered one year old on January 1st.

The change to the international age counting system was met with mixed reactions in South Korea. Some people welcomed the change, saying that it would make things more consistent with the rest of the world. Others were more skeptical, saying that it would be disruptive and confusing.

Only time will tell how the change will ultimately impact South Korea. However, it is clear that the country is now officially a year or two younger.
