Theory:Timeline - Fourth Doctor

This page lists appearances of the Fourth 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 assumed, much like their TV story counterparts, that each novel or audio series their published/numbered order is the order they occur in. 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. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Companions
Due to the nature of travel throughout season 12, any story featuring TARDIS travel with Harry Sullivan (other than TV: The Ark in Space) must take place after TV: Revenge of the Cybermen and before TV: Terror of the Zygons. Any story with Sarah Jane Smith must take place before TV: The Hand of Fear. Any story with Leela must take place after TV: The Face of Evil and before TV: The Invasion of Time. Any story with K9 Mark I must take place after TV: The Invisible Enemy and before TV: The Invasion of Time. Any story with K9 Mark II must take place after TV: The Invasion of Time and before TV: Warriors' Gate. Any story with Romana I must take place after TV: The Ribos Operation and before TV: Destiny of the Daleks. Any story with Romana II must take place after TV: Destiny of the Daleks and before TV: Warriors' Gate. Any story with Adric must be set after TV: Full Circle.

Costume
The Fourth Doctor has an advantage when dating his stories due to his costume. The Doctor started out with a small red coat, a rainbow scarf, and blue geans. His coat soon grew to a larger deep brown coat. Eventually, his costume turned into the "red" version. This makes dating very simple when looking at how the Doctor is dressed.

Series basics
The Fourth Doctor's stories can be sorted roughly by which companions he travels with and also the medium in which the companions first appeared together.
