How old is someone born in 1991?

Zodiac and school year
1991 is the year of the Goat in the Korean/Chinese zodiac. Someone born in 1991 typically entered elementary school around 1998 and, entering university near age 20, would be class of '10 (학번). These are the quick facts Koreans look up alongside age.
Western age vs Korean age
Korean age adds 1 at birth and everyone ages together on New Year's Day, so it runs 1–2 higher than Western age. Western (만) age starts at 0 and increases on each birthday. Since the 2023 reform, "age" in laws and services means Western age unless a specific counting age is stated (e.g. some school-entry or military rules use 연 나이 = current year − birth year).
