1.Hindi
जन्मदिन की शुभकामनाएँ, janmadin ki shubhkaamnaayein. This is the formal, written form: correct on a card, in a message to an older relative, and in anything a family group will read. Between friends it sounds stiff, and what people actually say is either happy birthday or जन्मदिन मुबारक हो, janmadin mubarak ho, which is warmer and lighter. Both are correct. They are not interchangeable in tone.
