FAQ

Why are the three ages for 1958 all different?

Counting age starts at 1 at birth and rises every 1 January, giving 69 in 2026. Year age is 2026 − 1958 = 68. International age is 67 or 68 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 1958-born person appears as 67 before and 68 after the birthday on 2026 paperwork. Laws that count by year age — conscription, the Youth Protection Act — still use 68.

Does the early-birthday rule affect people born in 1958?

Yes. Up to the 1965 school entry, January–February births started school with the cohort born the year before, so someone born in January or February 1958 may be in the same school year as those born in 1957. The table above assumes a March–December birth.

What is the zodiac animal for 1958?

The Dog — Musul in the sexagenary cycle. The zodiac follows the lunar year, so a birth before Seollal in January or early February 1958 counts as the previous year’s Rooster. The exact Seollal date is in the lunar converter.
