A curfew is a kind of law that says that certain things can't be done for a certain amount of time. In its most literal sense, a curfew is a law that tells people when they must stay inside, usually at night.

The French word couvre-feu, which means to put out fire, is the source of this English term.

In medieval times, the word was adopted into the English vocabulary as curfeu, and in modern times, it became curfew.

According to William the Conqueror, the actual meaning of the term is the rule to extinguish all flames and fire lamps by the ringing of the 8 o'clock bell to prevent fire accidents in wooden houses.

This law is still in effect today to prevent groups of more than four people from congregating in public places for a predetermined amount of time.

When riots or public outrage take a dangerous turn and the police are unable to control the crowd, a curfew is imposed.

The severity of the issue determines how long the curfew will last. Curfews are sometimes imposed for an indefinite amount of time.

In certain spots, curfews are upheld around evening time, while in others, they are implemented for a couple of hours during the day.

Curfews are sometimes temporarily lifted or relaxed to let people plan for their essential needs.

Everyone is instructed to remain inside their homes when this law is in effect.

The motivation behind monumental a time limit is to keep individuals from social occasions outside and possibly making further unsettling influences.

Curfew laws of this kind are in place in several nations worldwide.

According to section 24(1) of the Special Powers Act of 1974, the District Magistrate in the case of district administration, and the Police Commissioner in metropolitan areas, can, under the supervision of the government, issue orders requiring special written permission before anyone can leave the premises in Bangladesh.

If any person contravenes any order made under this section, he shall be punishable with imprisonment for a term which may extend to one year, or with a fine, or with both, section 24(2) of the Act says.
