International age (만나이) is the world standard: 0 at birth, +1 on each birthday. Korean counting age is usually 1–2 years higher because it starts at 1 and increments on New Year. If your birthday has not passed this year it is 2 years higher; once it has passed, 1 year higher.

Calendar-year age is current year − birth year, ignoring your exact birthday. It is used for things like school grade and military service eligibility, so everyone born the same year shares it.
