After looking at this thread and seeing Astroboy’s reference to the fact that Koreans are considered a year old when they are born, I just wanted to explain my understanding of the Korean age system.
When a Korean tells you his age, he’s not really telling you how many years it’s been since he was born, but rather the number of years in which he’s been alive. The year a baby is born is his first year. As soon as the next year starts then that’s his second year.
A baby born in November of 1980 is 1 in 1980, and then in January of 1981 he’s 2. This is not really as confusing as it sounds because you don’t ask, “How old is the baby?” you ask “How many months old is the baby?” and they will tell you.
Koreans celebrate their birthdays but they don’t get older on their birthdays. Everyone’s age goes up with the turning of the year, traditionally with the eating of rice-cake soup for the lunar new year. Eating dduk guk is eating another year of age. (Although not eating it doesn’t help keep you younger, apparently). The time between the Western new year and the lunar new year is a little hazy. I knew a girl who was born in January and counted herself part of the previous year, since the next year hadn’t started yet by the lunar calendar.
To figure out how old you are by the Korean system, add one to your age if you’ve had your birthday this year, and add two if you haven’t.
