Korean Age

hey guys!! i'm gonna be talking about Korean age, cuz many ppl gets confused
international age counts ur age by the birthday, right? and u r 0 year old when ur born. but in korea, we count our age by the year, not birthday, and we're 1 year old when we're born. for ex. if u were born in 2005, then on the day u were born, ur 1 year old and no matter what month or date u were born as soon as the 2006 new year day comes (1st jan), ur 2 years old. so it's easy to think that ur age changes every 1st of january and ur 1 year old when ur born.
thx guys!! XD
