Theory:Timeline - Third Doctor

This page lists appearances of the Third 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, much like its TV story counterparts that for each novel or audio series their published/numbered order is the order they occur in. This does not apply to short stories which are often ambiguous about their placement. There are also many gaps between stories.

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 DocOhoReviews, Doc Oho's Book Reviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks Databank, Whopix, Big Finish forums, The Whoniverse and The Divergent Universe forums. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Additionally there are statements on the back of Virgin Missing Adventures and many BBC Past Doctor Adventures novels that state between which TV stories the novel takes place between. These can be used to narrow the field, and should be viewed as the only placing for these novels.

Limiting factors
Any stories involving the Doctor travelling around several destinations in his TARDIS should take place following TV: The Three Doctors, prior to this he is limited to travels "on assignment" for the Time Lords. Any limited trip with Jo Grant must take place after TV: Colony in Space. Any story where he is not on assignment but travelling freely with Jo must take place after TV: The Three Doctors and before TV: The Green Death. Any story with Sarah Jane Smith must take place after TV: The Time Warrior and before TV: Planet of the Spiders.
