The day a law or an amendment starts to apply. It is often months or years after promulgation, so that people have time to prepare. The Ministry of Justice's English usually says a law "comes into force" or "comes into effect", and sometimes calls the day its "enforcement date". Its "enforcement" more often means the word's other sense, carrying a law out, as in an Order for Enforcement (施行令), the Cabinet Order (政令) that sets out the details for carrying out an Act.
