Geographically the story is confined to a small area near the Thames River in South Kensington, a suburb of London; it is the shift in time that makes the setting unusual. The story ostensibly opens in the year of its telling, 1895, in the home of the unnamed time traveller.
As the traveller takes over the role of narrator, the machine moves him into the year A.D. 802,701. Society has evolved into two races, the upper-world Eloi and the lower-world Morlocks. The narrator remains in the future for a week, during which time most of the action occurs.
