FAQ

Why are the three ages for 1948 all different?

Counting age starts at 1 at birth and rises every 1 January, giving 79 in 2026. Year age is 2026 − 1948 = 78. International age is 77 or 78 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 1948-born person appears as 77 before and 78 after the birthday on 2026 paperwork. Laws that count by year age — conscription, the Youth Protection Act — still use 78.

Does the early-birthday rule affect people born in 1948?

Yes. Up to the 1955 school entry, January–February births started school with the cohort born the year before, so someone born in January or February 1948 may be in the same school year as those born in 1947. The table above assumes a March–December birth.

What is the zodiac animal for 1948?

The Rat — Muja in the sexagenary cycle. The zodiac follows the lunar year, so a birth before Seollal in January or early February 1948 counts as the previous year’s Pig. The exact Seollal date is in the lunar converter.
