A curfew is a rule that sets a specific time when individuals, often children or teenagers, must be home or indoors. This practice is commonly used by parents to ensure the safety of their children and to promote responsible behavior. Curfews can also be enforced by local governments during emergencies or to maintain public order. Curfews can vary in time and duration, depending on the age of the individuals involved and the reasons for the curfew. For example, some cities may impose a curfew for minors after a certain hour to reduce crime or disturbances. These regulations aim to protect the community and encourage young people to follow guidelines.
