FAQ
Why are the three ages for 1975 all different?
Counting age starts at 1 at birth and rises every 1 January, giving 52 in 2026. Year age is 2026 − 1975 = 51. International age is 50 or 51 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 1975-born person appears as 50 before and 51 after the birthday on 2026 paperwork. Laws that count by year age — conscription, the Youth Protection Act — still use 51.
Does the early-birthday rule affect people born in 1975?
Yes. Up to the 1982 school entry, January–February births started school with the cohort born the year before, so someone born in January or February 1975 may be in the same school year as those born in 1974. The table above assumes a March–December birth.
What is the zodiac animal for 1975?
The Rabbit — Eulmyo in the sexagenary cycle. The zodiac follows the lunar year, so a birth before Seollal in January or early February 1975 counts as the previous year’s Tiger. The exact Seollal date is in the lunar converter.
