Index → Timey-wimey detector → Timeline - UNIT
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 UNIT in chronological order. 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, comic, audio or television series, their published, broadcast or numbered order is the order they occur in.

Note that the placing of UNIT stories is especially complicated due to the UNIT dating controversy.
