What is the literary time period of Fahrenheit 451 and what are the dates of it?

Ray Bradbury's Fahrenheit 451 first appeared in print in 1953, though it was based on a short story - "The Fireman" - published in 1951.  Bradbury's text, published after the end of World War II, can in many ways be considered part of the post-modern literary movement.  In reality, though, it contains not only of post-modern themes, but also those somewhat common in modernism before it.  The novel takes place at a time more of less contemporary with the publication of the novel.  As such, it takes place in the middle of the initial phase of the Cold War, a fact that filters through not only to the novel's content, but also the themes it explores.
