Frequently asked questions ❓

In 2026, someone born in 2004 is 22 if they've already had their birthday this year and 21 if they haven't. In Korean age they're 23, and their year age is 22.
Counting from 2026, a 21-year-old was born in 2004.
2004 is the year of the Blue Monkey. In the sexagenary cycle it's Gap-sin (甲申), and because the heavenly stem carries the element Wood (木), the animal picks up the color Blue. One catch: the tti turns over at ipchun, around February 4, so a birthday before that counts as the previous year's animal.
Yes. 2004 runs 366 days and February goes all the way to the 29th, so some people born in 2004 only get a real birthday every four years.
Korean age starts at 1 the day you're born, and everybody adds a year together on January 1 instead of on their birthday. That makes it one or two years higher than international age. Since June 2023, Korean law, contracts, and official documents all use international age, but you'll still hear Korean age in everyday conversation.
