What is the standard Korean phrase for an idol's birthday?
On a birthday line, the register does the quiet work: 생일 is the everyday word, but 생신 is the honorific that signals you know you're writing to a group's senior member. It's the same instinct that makes 태어나줘서 고마워요 — "thank you for being born" — a real fan-culture idiom rather than a textbook phrase: it only lands said warmly, in polite 존댓말.
To say happy birthday in Korean to a K-pop idol, use 생일 축하해요 (saengil chukhahaeyo) — the polite form used in nearly every fan letter. Use 생일 (saengil, standard) for same-age and younger idols, and 생신 (saengsin, formal) only for group seniors. Keep the message short so it fits on a handwritten card. Start with one of the three short phrases below, then practice the Korean handwriting stroke by stroke with the free tool.
