When was the caretaker by Harold pinter set?

Answer 1

It was first performed in 1960. The only problem, as with many of Pinter's plays is that precisely "when" it is set remains unclear - but then that's the point (at least partly)

Though Pinter isn't entirely an "absurdist" writer, he does seek not to provide too much context. Much of the appeal of the text is that it raises as many questions as it answers and leaves the audience to work out the nature of relationships. There are some uses of language or cultural references which make the play feel dated, but beyond that, it is possible to be quite open-ended with particular production ideas.
