=== ''Twin Peaks'' (1990-91) ===
Although the show contains many inconsistencies, it is commonly agreed that the events take place in February and March 1989.

In the [[Pilot]], Dale states into his tape recorder that the date is [[February 24]], and Ronette's medical chart in [[episode 8]] confirms that her hospital admission on that date is [[February 24]], [[1989]]. This year is given in subsequent releases, including ''Twin Peaks: Fire Walk with Me'' and ''The Secret History of Twin Peaks''. Occasionally, incidental dates visible onscreen differ &ndash; for instance, [[Emory Battis]]' book in [[episode 6]] describes events up to February 25, 1990, when the date at the time should be March 2, 1989.

Before the original TV broadcast of [[Episode 24]], a short vignette featuring [[Dale Cooper]] summarizing recent episodes uses the episode's airdate (Thursday, [[March 28]], [[1990]]) rather than the in-story date.

=== ''Twin Peaks: Fire Walk with Me'' ===
The film establishes Laura's murder to be on a Thursday to Friday night.

=== ''The Secret Diary of Laura Palmer'' ===
The novel was written to place Laura's death after October 31, 1989, with her birthday being July 22, 1972, contrary to the TV show which places her death on February 24, [[1989]] at age 17. To compensate, the dates for most events that do not otherwise conflict with the series or ''[[Fire Walk with Me]]'' are placed one year prior. The exceptions are two chapters concerning [[Lawrence Jacoby]], which remain set in November [[1988]] and January [[1989]] for consistency with dialogue in the series establishing that Laura started therapy "six months ago," around August 1988.
=== ''My Life, My Tapes'' ===
The account of [[Caroline Earle]]'s murder by her [[Windom Earle|husband]] is set in [[1979]], contradicting dialogue in [[Episode 17]] that places it four years prior (c. [[1985]]). To account for this, all events in Part 5, Chapter 2 (April [[1978]]) through Part 6, Chapter 1 (July [[1980]]) are advanced forward six years ([[1984]] &ndash; [[1986]]).
=== ''Access Guide to the Town'' ===
The introductory letter by Mayor [[Dwayne Milford]] is dated [[1991]], the actual publication year for the book itself. However, the fictional guide was apparently written in mid-[[March 1989]]; [[Leland Palmer]]'s death is referenced, but not that of [[Josie Packard]].

=== ''The Secret History of Twin Peaks'' ===
The framing story of the novel, involving the recovery of the Archivist's [[dossier]], is set in July and August [[2016]]. However, the sequel ''The Final Dossier'' indicates the dossier was discovered ''after'' the events of the [[Twin Peaks (2017)|limited series]], placing it in October 2016 or later.
=== ''Twin Peaks'' (2017) ===
The current dating scheme originates from dialogue in [[Part 9]], which indicates that the date in [[Twin Peaks, Washington|Twin Peaks]], [[South Dakota]], and [[Las Vegas]] is [[September 29]]. As the events surrounding Dale Cooper in Las Vegas cover only a few consecutive days, this allows for a reasonable extrapolation of most scenes to a particular date. In [[Part 3]], the date of Cooper's car crash is "[[September 22|9/22]]," although this may be an oversight. In another possible error, [[Lucky 7 Insurance]] appears to be open for business on seven consecutive days, [[September 26]] &ndash; [[October 2]].

The year is not stated in the series, other than indications of "twenty-five years" after the events of the original series. ''[[Twin Peaks: The Final Dossier]]'' establishes the year as [[2016]], actually twenty-seven years and seven months later, although this contradicts the date of Hastings' arrest ([[September 23]]) being stated as a Saturday. ''[[The Search for the Zone]]'' tie-in website indicates that Hastings last updated his blog in November [[2015]] and implies that he had gone missing by this time.

It is unclear to what degree the events taking place in and around [[Twin Peaks, Washington|Twin Peaks]] are concurrent with those involving [[Dale Cooper]] and [[Dale Cooper (doppelganger)|the doppelganger]], or even other Twin Peaks-set scenes. For example, the [[Great Northern Hotel]] key mailed by [[Jade]] in [[Part 5]] arrives in town at some point during [[Part 7]], which (if set contemporaneously) would require a transit time of less than a day. [[Andy Brennan]]'s watch in Part 7 shows that the date is the 10th, possibly [[September 10]].
