How age is calculated
Your age starts at 0 on the day you're born and goes up by one on each birthday. This is the international standard, and since June 2023 South Korea uses it for laws and official documents too.
- Your age: current year − birth year, minus 1 if your birthday hasn't come yet
- Year age: current year − birth year (used for some Korean laws such as military service)
- East Asian age: year age + 1. You're 1 at birth and everyone gets a year older on New Year's Day
Born on February 29?
In non-leap years, your birthday counts as passed once March 1 arrives. The zodiac animal is based on the calendar year.
