Why do firemen only work at night in Fahrenheit 451

In Fahrenheit 451, the alarms to burn always occurred at night because it was a spectacle, a fire seems brighter and more amazing in the contrast of the darkness. Part of a firefighter's job was to spread the fear of books and the consequences for having them, so the best way to achieve this was to burn the books at night.

Fahrenheit 451 is a novel written by Ray Bradbury in 1953. The novel is about an American society in the future, where books are outlawed and firemen burn any house that contains them. The novel is regularly interpreted as being critical of state-sponsored censorship and the role of book burning as a way of suppressing dissenting ideas. A film adaptation of Farenheit 451 was released in 1966.
