Use our Korean age calculator to determine your age according to the Korean age system. This system means that your age in Korea will be one or two years more than American age (Western or International age).

It adds one year to a person’s age at the start of each calendar year, regardless of the actual birthdate.

What Is Korean Age System?

It is a way South Koreans calculate their age. According to it, a baby is already 1 year old at the time of birth and his/her age increases on January 1st of every year rather than traditional birthday. This is because Koreans examine pregnancy months (Gestational Period) as 1 year of age.

Your Korean age will be one or a couple of years more than your actual age.

Korean Age Vs American Age (Example):

For example; If your Korean age is 22 (스물두 살, pronounced as “seu-mul-du sal”), your International age might be either 21 (스물한 살, pronounced as “seu-mul-han sal”) or 20 (스무 살, pronounced as “seu-mu sal”).

People in North Korea also consider this aging system because both countries have identical social, legal, and cultural norms. However, the practice is supported in South Korea only on a wider scale.

In Korea, a Child Becomes 1 Year Older on January 1st:

Where American age tells the number of years, months, or days a child has lived, Korean age tells the years, months, or days a child has experienced.

Based on this fact, if a child is born on December 31, 2023, he/she will be already 1 year old. On the very next day (January 01, 2024), his/her age will become 2 years.

Remember that the Korean age is just a cultural practice and it is not used for official purposes, including Birth Certificates, Passports, Identity Cards, Educational Documents, etc. For these documents, every Korean will use his/her International age.

How To Calculate Korean Age?

If you want to calculate your Korean age, consider the following formulas:

  • Korean age based on the current DOB:

Add 1 to the current year, then subtract the year of your birth, and you will get your Korean age.

Korean age = ( Current Birthdate - Year of birth ) + 1

  • Korean age if your birthday has passed:

If your birthday has passed then add 1 to your current age:

Korean age = your age + 1

  • Korean age if your birthday has not passed:

If your birthday hasn't passed yet, then you can add 2 to your current age:

Korean age = your age + 2

How To Use The Korean Age Calculator?

If you choose the year of birth then:

  • Enter the current year & birth year

If you select the current age, then:

  • Set the option for - Has your birthday passed?
  • Enter Your current age

Once you are done with inputs, click ‘Calculate

Why Is The Korean Age Important?

In South Korea, people consider the time spent in the womb as a complete year. This is why when a child is born there, he/she is already a year old. Even if you travel to Korea, you become one or two years old. But this does not mean your actual age also increases.

This traditional age counting system is considered in social settings and in workplaces where age hierarchies are very significant.
