Usage note
Korean has a separate honorific word for 'birthday' — 생신 (saengsin) — used only when wishing someone significantly older (like a parent or grandparent) a happy birthday. Using plain 생일 with an elder is technically correct but shows less cultural literacy; switching to 생신 축하드립니다 demonstrates real respect. Also note: Korean birthday messages often include wishes for health (건강하세요) or happiness (행복하세요) — more so than the English habit of keeping it to 'happy birthday' alone.
