Theory:Timeline - The Doctor's Age

This page lists the age of the Doctor over the course of the franchise. 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, comic story and audio series their published/numbered order is the order they occur in. There are also many gaps between stories.
