A curfew is a regulation that sets a specific time by which individuals, often minors, must return home or be indoors. It is commonly enforced by parents, schools, or local governments to promote safety and responsibility. Curfews can vary in timing and rules depending on the community or household. In many places, curfews are implemented to reduce crime and ensure the well-being of young people. For example, some cities may have a curfew law that prohibits minors from being outside after a certain hour without adult supervision. These laws aim to protect youth and maintain order in the community.
