FAQ
Why are the three ages for 2015 all different?
Counting age starts at 1 at birth and rises every 1 January, giving 12 in 2026. Year age is 2026 − 2015 = 11. International age is 10 or 11 depending on whether the birthday has passed. All three are correct; they are used for different things.
Which age applies since the 2023 unification?
From 28 June 2023 Korean law and administration use international age unless a statute says otherwise, so a 2015-born person appears as 10 before and 11 after the birthday on 2026 paperwork. Laws that count by year age — conscription, the Youth Protection Act — still use 11.
Does the early-birthday rule affect people born in 2015?
No. From the 2009 entry everyone born in the same calendar year enters together, so all 2015 births share a school year. The rule ended with the 2008 entry (births in 2001).
What is the zodiac animal for 2015?
The Goat — Eulmi in the sexagenary cycle. The zodiac follows the lunar year, so a birth before Seollal in January or early February 2015 counts as the previous year’s Horse. The exact Seollal date is in the lunar converter.
