意思
To become legally effective, usually referring to a law.
文化背景
In Brazil, the 'vacatio legis' (the time before a law enters into vigor) is usually 45 days unless specified otherwise. This is a common topic in 'Concursos Públicos' (civil service exams). In Portugal, laws enter into vigor on the day determined by the law itself, or, if not specified, on the 5th day after publication in the 'Diário da República'. The phrase is deeply tied to the 'Princípio da Publicidade', which states that no one can be punished by a law that hasn't officially 'entered into vigor' through public notice. In Brazilian startups, you might hear 'entrar em vigor' used for new software features or 'sprints', though 'lançar' is more common. It adds a layer of 'seriousness' to the update.
Use in Exams
If you are taking a Portuguese proficiency exam, use 'entrar em vigor' instead of 'começar' when talking about government or society. It instantly boosts your score.
No 'no'!
Remember: it's 'em vigor', never 'no vigor'. Adding the article makes it sound like you are talking about physical stamina.

The 'Law that doesn't catch'
Even if a law 'entra em vigor', Brazilians might say 'essa lei não pegou' if people don't follow it. It's a fascinating look at the gap between law and practice.
