Theory:Timeline - Tenth Doctor

This page lists appearances of the Tenth 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, anthology, 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 Reference Guide and Doctor Who - The Complete Adventures, as well as Lance Parkin's AHistory and other sources that allow us to make observations, such as The Whoniverse, Doctor Who Reviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks databanks and the Big Finnish forums. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Limiting factors
Any story with Rose Tyler travelling must be after TV: The Christmas Invasion and before TV: Army of Ghosts. Any story with Martha Jones travelling must be after TV: Smith and Jones and before TV: Utopia. Any story with Donna Noble must be after TV: Partners in Crime and before TV: Turn Left.

Though multiple stories that predate TV: Journey's End feature the Doctor travelling alone, TV: Smith and Jones and TV: Partners in Crime both strongly imply that it hasn't been long since the Doctor travelled with Rose and Martha.
