The time loop or temporal loop is a plot device in fiction whereby characters re-experience a span of time which is repeated, sometimes more than once, with some hope of breaking out of the cycle of repetition.[1] The term "time loop" is sometimes used to refer to a causal loop;[1][2] however, causal loops are unchanging and self-originating, whereas time loops are constantly resetting: when a certain condition is met, such as a death of a character or a clock reaching a certain time, the loop starts again, possibly with one or more characters retaining the memories from the previous loop.[3]
