Korean age calculator
An old Korean man I saw in Jinju.
In Korea, everyone is 1 from the time they are born. And everyone gets a year older on New Year’s day. So your Korean age is always either one or two years older than your Western age. And yes, a baby born on New Year’s Eve can be two years old the next day, although in practice people wait awhile before they start talking about somebody’s Korean age.
Working out your Korean age can be tricky. Even more so because Koreans frequently go by the Lunar (Chinese) New Year. And that is when your head starts to hurt. It hurts even more when you try to figure out how to algebraically parse things to make a javascript Korean Age Calculator, but that is what I’ve done. So here it is – put in the relevant information and it will convert your age to Korean years, according to both the Solar and Lunar (Seollal) calendars. Have fun.

How to calculate your Korean age (and how this works)
Having spent a good hour and a half thinking about how to calculate your Korean age to make this thing, I can now tell you the easy way to work out your Korean age, which is also how the calculator works.
As you are 1 year old when you are born, and as a new year will inevitably come around before your first birthday, it is impossible to ever catch up to your Korean age. However once a year, on your birthday, you get temporarily closer by one year. So, to put it simply – in a given year, before your birthday, your Korean age is your Western age plus two; after your birthday, it is your Western age plus one.
To calculate your age by the lunar calendar is only slightly more complex; we just need to change “the start of the year” to “the start of the lunar year”. So, go back to the last Lunar New Year and repeat the process. Add two before your birthday, and one afterwards.
Simple.
As to whether to use the lunar or solar new year, from everything I’ve read and everyone I’ve asked, it’s a matter of personal preference. For most people, it only makes a difference for one month of the year or so – the period between January 1 and the start of the lunar new year. However if you have a January or early February birthday, it makes a difference for the rest of the year. Want to appear mature to the handsome oppa? Go for the higher number. Mourning your lost youth and despairing over the swiftness of time’s passing? You know what to do. Although truthfully in that situation your best bet is to play dumb about the whole Korean age thing. It invariably makes you feel old.

oh how i wish the legal age in Korea was 18.
this confuses me.i was born on new year’s day exactly so does that mean i add 2years to my age or just 1?
March 25th, 2013 at 2:48 amIf you were born on New Year’s Day, you should always add one year to get your Korean age. New Year’s eve, always add 2, except for the actual New Year’s eve.
March 25th, 2013 at 7:54 amI’m a bit confused. I was born in early February in 1995.

June 1st, 2014 at 8:29 amThis is totally messed up… Okay I give you credit for the fact that this is an interesting topic but those of us who are already old enough and don’t welcome age calculators magically adding TWO YEARS to our age are grumbling unhappily right now. :/ (kidding… 😛 grumble grumble… not really)
I’ve always been curious, though, because I was born in Korea in the mid-70’s and have been promised by my mom that the birthday that I have always understood to be mine was based on the Gregorian calendar. But knowing how focused they are in Korea on the lunar calendar (even now), I’m never quite sure. Is there any way to find out? Did they start using Gregorian dates for official birth records at some specific point in Korea?
June 12th, 2014 at 5:58 amso, i’ll just say i’m in my mid-50s
July 11th, 2014 at 2:37 amI was Born on November 14 1994 i am only 20 I am only 21 years old in Korea. The Korean age system is using in North and South Korea for calculating the age in the western age plus they will add one year or sometimes two years in during Chinese Lunar New Year

October 21st, 2014 at 9:53 pmi was born on jan 26 im 14 how old am i in korea im turning 15 im a month
November 22nd, 2014 at 6:33 pmI’ve lived in Korea for almost eight years and have a nightmare trying to explain this to people.
February 20th, 2015 at 12:08 pmBasically if you are born on 31st December, you are one day old, but also one year old. The next day, despite being only two days old, you become two years old (Korean age).
When I turned thirty, I introduce myself to Koreans, I just tell them the year I was born and trust that they have sufficient math skills to figure it out for themselves wether to call me ‘hyung’ or not.
It’s like just adding 2 years on your age,but this helped me a lot.Thanks to this website
May 4th, 2015 at 8:41 pmSo in Korea, do they celebrate birth dates, but they only get older on New Year’s (to them)?
June 4th, 2015 at 10:22 ami’ll stick to my solar age after all my passport reflects the year i was born. i wonder if korean age computation is the same as chinese way of computing age.
June 8th, 2015 at 4:02 pmwow I’m 15 (13 in America but my birthday is in august so i see why its 15). so in Korea one more year and i can drive XD…. right? is driving age different too?
July 13th, 2015 at 7:59 amSo does that mean the k-pop idols are younger when they come to the U.S.? How do you convert someone’s age back? Say they are 23 in Korea is there age going to change if they move to the U.S.?
July 23rd, 2015 at 11:20 amI am 12 this year and my birthday is on 30 June so will I be 2 or 1 year older?
August 12th, 2015 at 7:52 pmHi, I am a little confuse about ‘Have you had a birthday since the last Lunar New Year (early February-ish)?’ Can you please explain it more in depth?
My Korean age (solar) is 23 and my birthday is in October.

I’m still kind of confused. So when you haven’t had your birthday yet you’re two years older but when you have you’re only one?
