Korean Age (Counting Age): A method of age calculation that starts at 1 year old in the year of birth, and increases by 1 year every New Year's Day (January 1).

Example: A baby born on December 31 becomes 2 years old the next day, January 1.

Note: As of 2023, legal/official age in Korea has been unified with the international age, but Korean ageis still used in everyday life.
