The Wheel of time or wheel of history (Kalachakra) is a concept found in several religious traditions and philosophies, notably religions of Indian origin such as Hinduism and Buddhism, which regard time as cyclical and consisting of repeating ages. Many other cultures contain belief in a similar concept: notably, the Q'ero Indians in Peru, as well as the Hopi Indians of Arizona.

The Wheel of Time is a series of high fantasy novels written by American author James Oliver Rigney Jr., under the pen name Robert Jordan. Originally planned as a six-book series, The Wheel of Time spanned fourteen volumes, in addition to a prequel novel and a companion book. Jordan began writing the first volume, The Eye of the World, in 1984. It was published in January 1990.
