FAQ

How is international age calculated?
Subtract your birth year from the reference year, then subtract one more if your birthday has not yet passed this year.
What is the difference between year age and Korean counting age?
Year age is this year minus your birth year. Korean counting age counts the birth year as age 1, so it is the year difference plus 1.
