Korean Age Calculator

The Korean age system is different from the international age we commonly use. In South Korea, people are considered one year old at birth, and everyone gains a year on New Year's Day (January 1st) instead of their actual birthday. This can make it confusing to calculate your Korean age, especially if you are used to the Western system.

To make it simple, we have developed a Korean Age Calculator that instantly determines your Korean age based on your birthdate and reference year. Whether you're wondering, "How old am I in Korean age if I'm 18?" or "Why is Korean age different?", this guide will provide all the answers.

How to Calculate Korean Age

The formula for calculating Korean age is straightforward:

$$\text{Korean Age}=(\text{Current Year}-\text{Birth Year})+1$$

However, when considering the month of birth, the Korean age may vary depending on whether your birthday has already passed in the year.

• If your birthday has passed, your Korean age = International Age + 1
• If your birthday has not passed, your Korean age = International Age + 2

For example, if someone was born in July 2008, and the current year is 2024:

• If today is August 2024, their Korean age is 17 (16 + 1).
• If today is March 2024, their Korean age is 18 (16 + 2).

Korean Age vs. International Age

If you are 14 years old internationally, your Korean age is either 15 or 16, depending on whether your birthday has passed.

Why is the Korean Age Different?

The Korean age system is unique due to cultural and historical reasons. Here’s why it differs from the American age system:

• Born at One Year Old – Koreans count the time spent in the womb, so a baby is considered one year old at birth.
• Age Increases on New Year’s Day – Instead of birthdays, all Koreans gain a year on January 1st.
• Traditional and Legal Use – While the international age system is now used for legal matters in South Korea (since June 2023), the Korean age is still widely used in daily life.
