Frequently Asked Questions
Korea has long used three age calculation systems in parallel: Korean age is the traditional folk method, where you are 1 year old at birth and everyone adds one year every New Year's Day; year age is calculated as the current year minus the birth year, often used for administrative purposes like military service and school enrollment; full age is the internationally recognized full age, where you add one year after your birthday.
