What is Korean Age?
Korean age is a way that South Koreans calculate their age. It is always one or two years more than your international age. In counting someone’s age in Korea, Koreans also consider a year in the womb, so everyone is one year old at birth. Everyone gets one year added to their Korean age on New Year’s Day. South Korea is also the only country that practices this.
How does the Korean age system work?
Here’s an easy way to think about it. Your Korean age will always be at least one year older than your international age. That’s because the Korean age adds one year because of the time you spent in the womb before being born (approximately one year).
Your age in Korea will change on New Year’s Day, not on your birthday. People in Korea still celebrate their birthdays on the day they were born and count their actual age. However, it doesn’t affect their Korean age as it changes on January 1st.
For example, if you were born on April 1st, you would still celebrate your birthday on April 1st. The international age will change for you, and not the Korean age, since it won’t change until January 1st. Korean age isn’t calculated based on your birthday.
Important note on the Korean age system
By June 2023, the government decided that the Korean age system would no longer be permitted to be used on official documents like medical and legal documents in South Korea. This new age system was established to reduce confusion in counting age by adopting the same system used in the rest of the world, which means only the international system will remain. This also means that Koreans will be a year or two younger as opposed to their age, which follows the traditional Korean age system.
South Koreans stated in a government survey conducted in September 2022 that after the new law goes into effect, they will start using the international system in their daily lives.
According to Yoo Sang-bum of the ruling People Power Party, this revision aims to reduce unnecessary socio-economic costs because having different ways of calculating age can be confusing and also leads to legal and social disputes.
As Korea changes the system for counting ages, South Korea’s Minister of Government Legislation, Lee Wan Kyu, oversees the official change. They also expect legal disputes, complaints, and social confusion caused by how to calculate a person’s age to be reduced greatly.
Korean Age Calculator
If you’re curious about your Korean age, you can use the Korean age calculator below. We also recommend you try the formulas we provide before using the Korean age calculator—more on that in a bit.
Enter your birth year below, and the Korean age calculator will show you your age in Korea.
The calculator above will use the Korean age formula and automatically calculate your Korean age.
Why is Korean Age Important?
Age in Korea is very important in Korean culture. Far more important than it is in Europe or the USA.
Often, the first question that people ask is, “How old are you?” People’s age is important not just for things like whether you are old enough to buy cigarettes and alcohol but for a whole variety of social interactions in Korea.
People use different languages when speaking to people of different ages. They expect people to act differently, with younger people expected to pour drinks or older people expected to pay for things.
Even the way you refer to your friends is based on their age; if they are a year older than you, they might be your 누나 (nuna) or 언니 (eonni), if they are younger, they will be your 동생 (dongsaeng).
With all this importance on age, answering the question “How old are you?” is very important. But the answer depends on the meaning of the question.
Why is the Korean Age System Different?
It is different from the international age (or Western age) because of two reasons. First, you are automatically one year old at birth. Second, you age another year because of the turn of the calendar year. Your date of birth doesn’t affect your Korean age.
In contrast, if you are a baby born in the USA, then you are considered to be one day old on the day after you are born. The nine months that you spent inside your mommy’s tummy are not considered part of your age. Your age increases by one each time your date of birth passes.
In Korea, on the day of your birth, you are considered one year old; the time you spent in the womb counts as the first year of your life (despite it only being nine months). Because of this, your Korean age is always at least one year higher than your international age or Western age. Then, the change of the year on January 1st automatically advances a person’s Korean age by one. You can read more about Korean months here.
What’s my Korean age?
If you’re asking yourself, “How old am I in Korean age?” there are three simple ways to get the answer. One of the easiest and simplest ways of knowing your age in South Korea is to add one year to the current year and then subtract your year of birth. This method will make you one year older than your Western age.
For example, if the current year is 2021 and the year you were born is 1992, you’ll add one year to the current year (2021 + 1) and subtract your year of birth. This is (2021 + 1) – 1992 = 30.
Another method of knowing your age in Korea or using the Korean system is by adding one year to your Western age if your birthday has passed upon age calculation and adding two years if your birthday hasn’t passed yet. And lastly, use the Korean age calculator.
Pick whichever one you like the best among these. We recommend using this calculator last. Let’s take a look at the examples of each method below.
1. Use the “Korean Age +1 Formula”
(Current year – Year of Birth) + 1 = Korean Age
If you were born in 1995 and the year is 2019:
(2019 – 1995) + 1 = 25 years old (Korean age)
2. Use the “Korean Age Birthday Formula”
Birthday has passed this year: Your Age + 1 = Korean Age
Birthday has not passed this year: Your Age + 2 = Korean Age
If you are 25 and your birthday has passed:
25 + 1 = 26 years old (Korean age)
If you are 25 and your birthday has not passed this year:
25 + 2 = 27 years old (Korean age)
This means that your Korean age will be one or two years more than your Western age.
3. Use the Korean Age Calculator
Using the online Korean Age Calculator is super easy; just input your birth year. We recommend using the formulas above first and then checking your answer by using the Korean age calculator afterward.
If you want to get a solid understanding of age in Korea, then you could try to calculate Korean age using formulas, like celebrities or people you know. Then, you can use the online Korean age calculator to check if you’re correct.
Keep in mind that the Korean age calculator uses today’s date. If you want to calculate a Korean age on a different date, use formulas 1 and 2.
Now that you know how to calculate Korean age, let’s look at some examples.
International Age vs Korean Age
Let’s compare the international age system and the Korean age system. Let’s use BTS’ Jungkook’s birthday as an example, which is September 1, 1997.
- International age:
- On January 1st, 2021, his international age is 23.
- On September 1st, 2021, his international age is 24.
- On January 1st, 2022, his international age is 24.
- Korean age:
- On January 1st, 2021, his Korean age is 25.
- On September 1st, 2021, his Korean age is 25.
- On January 1st, 2022, his Korean age is 26.
BTS Members Age
If you have already familiarized yourself with how to determine your Korean age from the example above, then a bit more practice won’t hurt! Here are the birthdays of the rest of the BTS members that you can use to practice knowing someone’s Korean age.
- Kim Namjoon – September 12, 1994
- Min Yoongi – March 9, 1993
- Jung Hoseok – February 18, 1994
- Kim Taehyung – December 30, 1995
- Park Jimin – October 13, 1995
- Kim Seokjin – December 4, 1992

When is the international age used in Korea?
Generally, the Korean age is used for social interactions with people, whereas the international age is used for more official things. For example, the legal age in Korea that is written on alcohol, cigarettes, movie posters, and so on is based on the international age.
Legal Age in Korea
For most things, the minimum age or legal age in South Korea is 19. This means an international age of 18.
Legal Drinking Age in Korea
The legal drinking age in South Korea is 20 years old (Korean age). This means you must have an international age of at least 19 years to legally drink alcoholic beverages in South Korea.
Underage drinking is controlled in South Korea by establishments doing ID checks. This prevents the selling of alcoholic beverages to people below the legal drinking age. The underage drinking law in South Korea remains not as strictly enforced as they are in some other countries.
Military conscription age in Korea
One of the duties of male South Koreans is to render service in the military for about 2 years. According to Korean law, all men aged 19 to 28 must perform compulsory military service.
When Do Koreans Celebrate Their Birthdays?
Everybody in South Korea shares the same birthday: January 1st or New Year’s Day. However, that’s not when they celebrate their actual birthday.
Everybody has their own birthday, complete with cake and candles. South Koreans celebrate their birthday on the day they were born, just like how the international age system works. But on your birthday in Korea, you are not considered one year older than the day before.
Instead, South Koreans all age on the same day, January 1st. No matter when your birthday is if you were 40 on December 31st, then on January 1st, you will be 41. Korean age works as if everybody was born on January 1st.
Video: Korean birthday celebrations
Here’s a video explanation of when South Koreans celebrate their birthdays.

Wow, we are the same age!
As age determines a complete host of social interactions in Korea, being of the same age can make everybody feel more comfortable.
If somebody that you have just met finds out that you are the same age as them, they will often be excited. This is because if you and your friend are the same age, neither person will have any of the social obligations that come from being a different age from the other.
Being the same age as another person has a special word in Korean: 동갑 (donggap). You will often hear the expression 우리는 동갑이다 (urineun donggabida), which means “we are the same age.”
As the age system in Korea is based on the year of birth rather than your birthday, you will always be the same age as this new friend, even if your birthday is the very next day!
Wrap up
Now you know the difference between the Korean and the international age and how to use the age calculator! This is an important aspect of Korean culture, so don’t be upset that you have suddenly become two years older. After all, age is just a number!
