Theory:Timeline - Twelfth Doctor

This page lists appearances of the Twelfth Doctor in the order in which he experienced them. This timeline is based upon observations of the Doctor Who universe and the events that occur during each of these stories. From these observations we have attempted to build a concise timeline. It is assumed that for each novel, comic, audio or television series, their published, broadcast or numbered order is the order they occur in.

The layout of this timeline is in part based on the observations on Doctor Who - The Complete Adventures, as well as Lance Parkin's AHistory and other sources that allow us to make observations, such as Doctor Who Reviews, Clive Banks databanks, Whopix, and the Big Finish forums. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Companions
Any story featuring Clara Oswald must come after TV: Deep Breath and before TV: Face the Raven. Any story featuring Nardole must come after the flashback in TV: Extremis and before TV: World Enough and Time. Any story featuring Bill Potts must come after TV: The Pilot and before TV: World Enough and Time.
