All of us would want it other ways with our age! But the way Korean age works is very interesting. 

I think I can say with confidence that all of us have contemplated why we have reached the age we are at right now! 

Well, in Korea, this has taken a whole new level. Age is a defining factor in Korea where people are particularly interested in knowing the other person’s age just to establish how to address one another. 

This is one of the reasons ‘oppa’ is very often heard. Unlike the rest of the world, Korea calculates age differently and you would be surprised at a lot of things that you never would have guessed. 

We have simplified it for you to understand. Read on.

International Age Vs Korean Age

In Korean age, a baby’s time in the womb of the mother is considered a year. So as soon as the baby is born, he/she is already one year old. 

Whereas the rest of the world calculates the time of the baby from the time of the birth to a year after that. 

But that is not all. Every new year, on the 1st of January, another year gets added up to a Korean’s age. 

So when you compare it to the rest of the world that is a +2. 

If a Korean tells you they are 30 years old, what they actually mean is that they are 28. 

This is not just a change in metric but a founded on a strong philosophy where while the rest of the world calculates the number of years lived by an individual, in Korea it is calculated on the number of years you have experienced. 

However, this Korean age does not work on their records. To adhere with other rules and regulations, Koreans have the normal age metric recorded on their passport and other official records. 

The cultural concept is strongly imbibed and embedded in the Korean lifestyle and their day to day interactions. So much that it is considered normal there! 

How To Calculate Korean Age?

Even though we have given you the basis of how Koreans calculate their age, there are a number ways for accuracy. 

  •    Post your birthday 

If you just got past your birthday date then you would have to add 1 to your normal age. 

For example

Normal age – 28

Korean age – 28 + 1 = 29 

  • Before your birthday 

If your birthday has not arrived yet then you would have to add 2 to your normal age. 

For example

Normal age – 28 

Korean age – 28 + 2 = 30

The next one could be slightly complicated but works. 

Add 1 to the current year and minus your birth year from the result you get from that. 

If my birth year is 1997 and the present year is 2021, here’s how it would go…

2021 + 1 = 2022

2022 – 1997 = 25

If neither of this seems to be working we suggest you use a Korean Age Calculator which will make the job easy and fast for you.

Why do Koreans always ask for the age? 

Like I mentioned in the introduction, Koreans make sure they know what your age is when they meet you in order to address you accordingly. 

In Korea and a lot of other Asian countries, it is disrespectful to call an older person with their name so there are terms that are used by relatively younger people.

This applies across all kinds of relationships, not just blood related. 

The informal addressing is picked up very carefully and directed towards people of the same age and within the family. 

So the next time you are in Korea, make sure you know the other person’s age before you go ahead and say their name! 

Korean Age Hierarchy Explained 

Although the age factor can demand respect everywhere in the world, it requires devotion in Asian countries!

In Korea there are certain conditions and etiquette that run the lives of citizens to maintain a disciplined and cultured lifestyle. 

Here are some. 

If you are out for lunch with family or friends, the oldest one in the bunch is required or rather expected to pay the bill.

The splitting of the bill does not work if you are considerably older than the rest of the gang. 

So the next time you are in Korea, you know what kind of people to go out for a bite to eat! 

Koreans bow to greet older people as a sign of respect. This is something that is shown in the media time and again. 

Older Korean people can without guilt ask younger people to do them favours. 

The formal speech has to be used by younger people to the older folks at home or just in general. 

This is very important since this sets a tone for your speech and shows the respect you hold for the older person and is one of the most basic requirements. 

The older one in the family or a clique of friends has the responsibility to lead the group. 

Does Korean age apply to foreigners?

Although it is not mandatory to convert your age when you are answering them, it is appropriate to cite your age in the Korean Age system so that it applies to them as well. 

A lot of westerners have admitted to citing their age in the Korean age system when they are in Korea just because that is their system and what they adhere to. 

Another reason why you should just get it off according to the Korean age system is because it can avoid a lot of confusion when it comes to the contradicting methods.

Situations you can ask for age in Korea? 

It can be a tad awkward to shoot the question to every person you meet just to adhere to etiquette. 

It usually arises when the person is around your age and you’re just quite not sure. 

When the other person is younger or older and it is apparent that you can use the right term, you are saved without having to bring up the question. 

Different ways you can address your age in Korea

One of the ways you can state your age is by simply stating it like the rest of the world.

Or you could state the year you were born in. 

Now addressing the elephant in the room, you can compare the actual age with the Korean age system. 

This can clarify a lot of cultural differences especially if you are in conversation with someone who is unfamiliar with the system and its workings. 

Citing Your Age In Korean

If you want to tell someone what you’re age is in Korean, here’s how you do it. I have given the list of ages in Korean from 18 years to 40 years old.

To say your age in Korean, you’ll have to add the following suffixes to the years in Korean given below.

If you’re talking to a person of the same age as you or a friend you should use the phrase – “-iya” or 이야 in Hangul.

For a person, you know generally but not intimately, you should use “-ieyo” or 이에요.

To a person older than you, use the honorific “-imnida” or 입니다.

FAQs about the Korean age system

Can I drink in Korea if I’m above 18?

If you’re a tourist visiting Korea, you can legally drink alcohol if you’re 19 years old or above.
The legal drinking age for Korean citizens is 20 years old. But as they count the time spent in the womb as one year and other countries don’t, you’ll be 20 in Korean years if you’re 19. 




Does Korean age follow the Lunar New Year calendar?

Yes, traditionally Korean culture has followed the Lunar New Year’s day as the day when everyone gets one year older. 
But in modern times, the Solar New Year (January 1st) is considered. So at this date, every citizen in Korea turns a year older, regardless of their actual birth date.
Funny thing is, if a child is born on the 31st of December, then according to Korean customs, he or she would be 2 years old on January 1st!
