Korean age calculator guide

This English page translates the Korean age calculator and calls calculateAllAges, calculateInternationalAge, calculateKoreanAge, calculateYearAge, calculateDaysUntilBirthday, and calculateDaysUntil100. It preserves the 2023 legal-age distinction, traditional Korean age, year age, birthday timing, zodiac, generation, and lived-days outputs.

Three age systems

International age is the legal default in Korea after the 2023 age-standardization change. It starts at 0 on the birth date and increases only after the birthday passes each year.

Traditional Korean age starts at 1 at birth and increases every January 1. Year age is birth year subtracted from reference year and is still useful in specific contexts such as school-year or military-age style calculations.

Birthday and lived-time outputs

The source calculates whether this year birthday has passed, whether today is the birthday, days until the next birthday, total days lived, total weeks lived, and total months lived.

The 100th-birthday counter calculates days until a date exactly 100 years after birth. It is a planning countdown, not a legal age rule.

Traditional calendar details

The Korean calculator also returns zodiac animal, heavenly stem, sexagenary-cycle name, generation label, and birth weekday. Those fields are cultural context, separate from legal age.

When an age is used for contracts, employment, alcohol, welfare, school documents, military service, or medical consent, check which age standard the institution actually applies.
