This represents an attempt to piece together a basic timeline of the series, using mostly information internal in the stories, and the chronology published in the author's blog, cf. a chronology of rivers-of-london books.
- In The Hanging Tree, a newspaper headline is mentioned, "UKIP TO ROCK WESTMINSTER", which was actually used by The Daily Express at October 9th, 2014.
- The Home Crowd Advantage takes place during the London 2012 summer olympics.
- Action at a Distance, an untitled Nightingale novella and an the short story Cock of the Wall are said to be "outside the main sequence".
- The "Moments" are actually dated in their respective subtitles to a specific year (1966, 2012, 2014).
