Spoilers are strongly policed here.
If this thread's title doesn't specify it's spoilery, don't bring any up.

This page lists appearances of the Sixth Doctor in the order in which he experienced them. This timeline is based on observations of the Doctor Who universe and the events in each of these stories. From these observations we have attempted to build a concise timeline. It is generally assumed, much like their TV story counterparts, that each novel, comic or audio series their published/numbered order is the order they occur in, although the audio stories that use the Peter Howell theme are often set before audio stories the Dominic Glynn theme. There are also many gaps between stories.

The layout of this timeline is based in part on the observations on Doctor Who Reference Guide and Doctor Who - The Complete Adventures, Lance Parkin's AHistory and other sources that allow us to make observations, such as DocOhoReviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks Databanks, the Big Finish forums, The Whoniverse and The Divergent Universe forum. None of these sources should be used solely as a source or considered a "true" timeline for stories.
