Happy Chuseok in Korean: 5 lines for Korean Thanksgiving

Close enough to be useful. Chuseok (추석) falls on the fifteenth day of the eighth lunar month — 25 September in 2026, with the country off from the 24th to the 26th — and like Thanksgiving it empties the cities. Families travel home, cook for a day, and give thanks for the harvest. The difference that matters for your card is the greeting.

Our translator carries a short list of situation expressions it reaches for before trying anything literal: birthday, comeback, support, love, thanks, enlistment, and how to say you are someone's biggest fan. Every one of those is something that happens to the idol. A holiday is the one occasion that happens to everybody at once, and it is the one not on the list. That gap is worth knowing, because in English "Happy Chuseok" looks exactly like "Happy birthday" and behaves nothing like it in Korean. A birthday takes 축하해요, congratulations. A holiday does not. Koreans wish each other a Chuseok spent well — 잘 보내세요 — the way you would say "have a good Thanksgiving" rather than "congratulations on Thanksgiving."

Turkey is the wrong picture. The Chuseok table is 송편 — small rice cakes folded into half-moons around a sesame or bean filling and steamed over pine needles — alongside 전, savory pancakes someone stands over a pan making the day before. Telling a person to eat plenty of it is an ordinary, warm thing to say in Korean, closer to "save room for pie" than to any formal wish.

The second line does more work than it looks. Idols work holidays: specials are taped in advance for the break, and an autumn comeback puts a group in a studio while everyone else is on the highway home. 푹 쉬세요 — rest deeply — is what Korean fans write when they know that. Our translator holds one polite register for everything, keeping casual forms for a single coined fandom word, and this is where that constraint earns its keep: to someone you have never met, 푹 쉬세요 reads as warm precisely because it stays polite.

Thanksgiving has no moon. Chuseok is dated to one — the fifteenth night of a lunar month is the night the moon comes full — and the old custom is to look up and make a wish. That is also why 한가위, the native Korean name for the day, survives inside the set greeting while 추석 is the word used for the holiday itself. 한가위 means the great middle of autumn, and it is the half of the pair that still sounds like moonlight rather than a date.

One line is enough here. A wish made under the harvest moon is not something to write twice.
