FAQ

Why are the three ages for 2013 all different?

Counting age starts at 1 at birth and rises every 1 January, giving 14 in 2026. Year age is 2026 − 2013 = 13. International age is 12 or 13 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 2013-born person appears as 12 before and 13 after the birthday on 2026 paperwork. Laws that count by year age — conscription, the Youth Protection Act — still use 13.

Does the early-birthday rule affect people born in 2013?

No. From the 2009 entry everyone born in the same calendar year enters together, so all 2013 births share a school year. The rule ended with the 2008 entry (births in 2001).

What is the zodiac animal for 2013?

The Snake — Gyesa in the sexagenary cycle. The zodiac follows the lunar year, so a birth before Seollal in January or early February 2013 counts as the previous year’s Dragon. The exact Seollal date is in the lunar converter.
