What is your Korean age?

I'm 20 and 21 in Korea
Reached the legal age to drink alcohol xD

22 and in korea I'm 23 :)

I'm 18 and my Korean age is 20 :D

I'm 18, but my Korean age is 20. I don't know how to feel...
Off-topic, though I just want to share. In Vietnam, they calculate age by one year when a woman is pregnant with the baby. Since I'm turning 19 this year, that means I'm actually 20 in Vietnam. 

I am 17

Im 20 in korea XD O_o

I'm 26 but in korean age 28~
Korean age is counted so that you add one year to your real age and when year changes to new year, you add second year. So before your birthday each year, your korean age is plus 2 years from your international age. When you have your birthday, it's +1 year. I don't know if this makes sense but I tried to explain xD

27 but in korea i would be 28 yikes :D
