What is Korean Age?

While it is a taboo to ask someone (especially women) their age in Western countries, one of the first things that native Koreans will ask you when you meet is your age. This is not due to lack of politeness–in fact, it is quite the opposite. Most of you learning Korean know that there are varied levels of politeness when conversing in Korean–and this is exactly why people will ask you your age—they want to know so that they can address you accordingly.

Your Korean age is ? years old.

However, when you give them your answer, you may see them nodding their head and stating a number that is higher than your actual age, or they may inform you that you are actually older in Korean age. Why is Korean age different? This is due to the different Korean age system, which is different from the international age. So if you see any K-Pop star saying their age in Korean, you should know their international age is different.

For example:

  • How old is Jungkook in Korea? His birthday is September 1, 1997.
    • In Korean age: He’s years old from January 1st until December 31st, 2018.
    • In international age: He’s years old until August 30th and years old after September 1st, which is his birthday.

What is the Korean age system? What is the difference between Korean age and American age (International Age or Western Age)?

1) In Korea, you are born one (1) years of age.

While Westerners consider newborn babies to be ‘zero’ years old upon birth, native Koreans actually calculate the time babies spend in their mother’s womb as a ‘year’ (although, technically, it is 10 months, they round it up to one year), so when babies are born in Korea, they are considered to be 한 살(han sal)=”one year old”. This automatically adds one year to the age that you may be used to. So when someone in Korea tells you, for example, that they are 스무 살(seumu sal)=“twenty years old”, they may actually be 열여덟 살(yeol yeodeol sal)=”18 years old” or 열아홉 살(yeolahop sal)=”19 years old”.

2) In Korea, you increase your age count on January 1st of every year, not on your birthday.

Now, why would a native Korean add two years to their ‘Western age,’ you may wonder. This is because Koreans automatically gain a year on January 1st, regardless of whether their birthday has passed or not.

  • International Age measures how long you have lived.
  • Korean Age measures how many years you have experienced.

For example, let’s say a child was born on December 31st, 2010. This child is already a year old, but only two days later, although the child is only three days old, he/she will already be two years old in Korean age, because everyone gains a year when the new year begins. So their actual age in international standards, or 만 나이(man nai), would technically be ‘zero’ years old, but when the parents are asked about the age of their child, they will probably answer, “한국 나이로 두 살이에요.”(hanguk nairo du sarieyo)=”My child is two years old in Korean age.”

One thing to keep in mind is that 만(man) is a Sino Korean word which does not come from the Chinese character ‘萬’, which means “ten thousand”, but from ‘滿’, which means “full” and it’s the same as the international age.

Another thing to keep in mind is that Korean age culture, however, is only a cultural thing–in order to avoid confusion and keep up with international standards, on official documents such as a passport or a birth certificate, everyone in Korea will use their 만 나이(man nai), or international age. This means that when you see the age of Korean sports stars at the PyeongChang Olympics, it will be their international age, not their Korean age concept.

How to Calculate Korean Age
What is my Korean age? How can I calculate my Korean age? Have you ever wondered? Calculating your Korean age is not very difficult! Here are 3 different but easy ways.

4. Why Do Korean People Always Ask Age?


Why Do Korean People Always Ask Age?Why do many Korean people ask your age when you meet them for the first time? How does age work in Korea?

실례지만 나이가 어떻게 되세요?
Sillyejiman naiga eotteoke doeseyo?
Excuse me, but how old are you?

It’s because they want to know which politeness level of the speech they should use and age decides how you address each other.

Why are there so many non-related 오빠(oppa)s=”older brother” and 누나(nuna)s=”older sister” in Korea?

Unlike in Western cultures where you use the same level of politeness regardless of age, in Korea there are various levels of politeness. This is one of the reasons why age asking is so important to native Koreans–they need to find out the age so that they can figure out how to address one another.

If you are 동갑(donggap)=”the same age”, you will likely find yourself forming a fast friendship–as can be seen in the way Koreans count their age, people who are born in the same year are all considered to be the same age.

If you look at the hit Korean movie 동갑내기 과외하기(donggapnaegi gwawehagi)=”private tutoring someone the same age”, the heroine, who is a freshman at college, starts private tutoring the hero, who is a senior in high school but born in the same year as her. This makes their situation tricky, as they are 동갑(donggap), but she is his teacher.

Usually, you will find that your classmates are the same age as you–you are a part of the same age group with the same experiences-everyone goes to school together, and moves up in age together at the beginning of every year. It is a great ice breaker and you find yourself becoming close friends when you find out that you are the same age. This is why when you are introduced to someone else through a mutual friend, you will find native Koreans automatically checking each other’s age so that they can figure out whether they can start using informal speech, or 반말(banmal), right away.


  • A: 몇 년생이세요?
    • (myeot nyeonsaengiseyo?)
    • ”What year were you born?”
  • B: 2000년생이요.
    • (icheonnyeonsaengiyo.)
    • ”I was born in 2000.”
  • A: 저랑 동갑이시네요…괜찮다면 말 놓아도 될까요?
    • (jeorang donggabisineyo…gwenchanttamyeon mal noado dwelkkayo?)
    • ”You are the same age as me…if it is okay with you, shall we speak informally?”
  • B: 그럴까? 그럼 편하게 말 놔.
    • (geureulkkayo? geureom pyeonhage mal nwa.)
    • ”Shall we do that? Then address me informally.”

5. Citing Age


Citing Age

You may have noticed in the dialogue above that ‘A’ asked ‘B’ how old they were by asking:
몇 년생이세요?
Myeot nyeonsaengiseyo?
What year were you born?

This is a common question asked by native Koreans when asking age, as they will likely figure out how old you are in Korean age by the year you were born. So instead of answering with your actual age, you could simply reply by giving your birth year as an answer—just let them know the year you were born, or you could just cite the last two numbers of the year you were born:


  • If you were born in 1990, you could say:
    • 1990년생입니다. (1990nyeonsaengimnida)=”I was born in the year 1990.”
    • 90년생입니다. (90nyeonsaengimnida)=”I was born in the year (19)90.”
빠른 __년생
Ppareun ___nyeonsaeng

Another age related expression that may throw you off is “빠른 년생 People.” We will describe why this phrase is used as it relates to the Korean education system. In Korea, the school year starts in March. This means the deadline to make it to a certain grade would be late February. ‘빠른 (ppareun) + insert year of birth’ refers to people that were born in either January or February, whose parents decided to let their children go to school with children born a year earlier.


If you were born in January, 1980, and went to school with classmates born in 1979, you would refer to yourself as 빠른 1980년생(ppareun cheongubaekpalsim-nyeonsaeng), or simply omit the first two numbers and say 빠른 80년생(ppareun palsim-nyeonsaeng). You can even say 빠른 80 (ppareun palgong). ‘Gong’ is another way to say 0 (zero) in Korean.

For example, say a child was born in February, 1999. The parents used to have two options–did they want their child to enter school as the youngest, or did they wait a year and let their child enter school as the oldest student? Depending on the decision that has been made, the child ended up going to school with friends who were born in 1998, or, those who were actually a year older than them. This means that other children born in 1999, who entered school a year later, had to refer to him/her as:

  • 오빠 (oppa) = older brother(addressed by a female)
  • 언니 (eonni) = older sister(addressed by a female)
  • 누나(nuna) = older brother(addressed by a male)
  • 형 (hyeong) = older sister(addressed by a male)

This system even confused native Korean people so it’s not been used since 2003. But those who entered elementary school before 2003 still see 빠른 년생 people. Just remember that these phrases are also used by native Koreans to refer to blood siblings, as well as non-related people who are senior to them.

Now if you ask someone their age and realize that they are younger than you, you can take the initiative and address them informally. However, in most cases, you will likely continue to use polite phrases until the recipient asks you to speak to them informally. And if you find out that someone is older than you, remember to use polite phrases and suffixes.
