How is the age counted?

If this year’s birthday has passed, subtract the birth year from this year; if not, subtract one more. Since June 2023 this so-called “full age” is the single legal age in Korea.

What is the zodiac animal based on?

The commonly used 1 January boundary. Some hold that it should follow the lunar new year, so people born early in the year may see it differently.

Why are the star-sign boundaries confusing?

Each sign starts on a different day of the month, so the split falls around the 22nd. The start dates are kept in a table here and read from it.

What is the difference between full age, year age and Korean age?

Full age subtracts the birth year once the birthday has passed — the default in Korean law and contracts since June 2023. Year age ignores the birthday and is simply this year minus the birth year; military service and youth protection law use it. Korean age is the old counting method: year age plus one.
