International age is what americans use, the western way of stating your age.
In korea, when you were born you're already 1 yr. old. Then, every new year, you become a year older... but when you celebrate your bday, whatever age you turned to that new year, that's the age you'll celebrate. Example, this new year I turned 16. On my bday, I'll celebrate my 16th bday...
this is based from what i've read...
any korean can correct me or agree with me... :D
