Romeo and Juliet is a play, not a historical document. It starts every time someone steps out on the stage and says "Two households, both alike in dignity."
However, Romeo and Juliet is one of the few Shakespeare plays where you can figure out the day of the week on which the events take place. Act 1 scene 1 takes place on a Sunday afternoon.
