This theme is intimately connected to "Youth," but also has a force of its own given Bradbury's focus on describing exact times of day and exact times of the year. In Something Wicked This Way Comes, different times of the day and different times of the year have their own particular personalities. Summer people are good while autumn people are evil. A boy born on Halloween and one minute after midnight is much darker and more prone to temptation than a boy born one minute before on October 30th. Three in the morning is a dangerous time of the night. Supporting these ideas, clock references and imagery run throughout the novel.
Nighttime is always represented as evil in Something Wicked This Way Comes.
Human beings are portrayed as clocks in the novel that can be sped up or wound backwards by the carousel.
