Understanding Korean Age Calculation

The Korean age system differs significantly from the international age system used in most countries. This calculator helps you determine your age according to the traditional Korean method.

How Korean Age Works

The Korean age system is based on two key principles that make it different from the international age system:

  • You are born at age 1: Unlike the international system where you start at age 0, in the Korean system, you are considered to be 1 year old at birth.
  • Everyone ages on New Year's Day: Rather than having individual birthdays, everyone gets one year older on January 1st, regardless of their actual birth date.

Calculating Korean Age

To calculate your Korean age:

  1. Take the current year
  2. Subtract your birth year
  3. Add 1 (because you're born at age 1)

For example, if you were born in 1990 and the current year is 2025:

Korean Age = 2025 - 1990 + 1 = 36 years old

Korean Age vs. International Age

For most people, their Korean age will be 1-2 years higher than their international age:

After your birthday in the current yearCurrent year - Birth yearCurrent year - Birth year + 11 year older

Cultural Significance

Understanding Korean age is important for several reasons:

  • Social Relations: Age determines social hierarchy in Korean culture, affecting language formality and relationships.
  • Legal Matters: Some Korean legal documents may reference both Korean and international ages.
  • Cultural Traditions: Many Korean celebrations and milestones are based on Korean age.

Recent Changes in Korean Age System

In December 2022, South Korea passed legislation to abandon the traditional Korean age system for official purposes, adopting the international standard instead. However, the traditional system remains culturally significant and continues to be used in everyday social contexts.

This calculator provides both ages, allowing you to understand how your age would be perceived in both systems.
