デビュー時の年齢の求め方데뷔 당시 나이는? — 달력을 섞지 않고 읽기

デビュー時の年齢の求め方

1. Take the full birth date from a verified profile.
2. Take the debut date from the agency / official chronology — not a viral “trainee reveal” year.
3. Compute international age on that debut day (completed years).
4. If you only have birth year, say “born in YYYY” instead of asserting an exact debut age.
