History of the chronology

There have been several efforts over the years to develop a chronology for the events depicted by the Star Trek television series and its spin-offs. This matter has been complicated by the continued additions to the Star Trek canon, and the scarcity of Gregorian calendar dates given in the show (stardates instead being used). The current Star Trek franchise logo Star Trek is an American science fiction entertainment series and media franchise. ... The Gregorian calendar is the most widely used calendar in the world. ... This article or section is not written in the formal tone expected of an encyclopedia article. ...

Original series

There are few references setting the original series in an exact timeframe, and those that exist are largely contradictory :

• In the episode, "Tomorrow is Yesterday", a 1960s military officer says that he's going to lock Captain Kirk up "for two hundred years", to which a bemused Kirk says, "That ought to be just about right".
• In the episode "Space Seed", it is said that Khan is from "two centuries" ago (1996), placing the episode in the late 22nd century
• In the episode "Miri", it is said that 1960 was around 300 years ago
• The episode "The Squire of Gothos" implies that the light cone of 19th century Earth has expanded to 900 light years, setting the episode in the 28th century.
• The episode "Metamorphosis" establishes that Zefram Cochrane, the inventor of the warp drive, went missing around 150 years ago, at the age of 87.

According to notes in The Making of Star Trek, the show is set in the 23rd century, and the Enterprise was supposed to be around 40 years old. Roddenberry says in this book that the stardate system was invented in order to avoid pinning down the show precisely in terms of timeframe.^[1] Roddenberry's original pitch for the series dated it "'somewhere in the future". It could be 1995, or maybe even 2995".^[2] Tomorrow is Yesterday is a first season episode of Star Trek: The Original Series. ... Captain James T.

Early chronologies

The Star Trek Spaceflight Chronology and FASA, a publisher of the first licensed Star Trek role-playing game, chose to take the Space Seed figure, adding a few years to make sure the events of the original series were in the 23rd century. This dating system is followed by other spin-off works in the 1980s, including Mr Scott's Guide to the Enterprise. This timeline system gives the following dates ^[3][4] This article is about the role-playing game company. ...

The Star Fleet Battles game was published in 1979, with a license only covering the original series.

TNG era and Okuda

Press materials for TNG suggested it was set in the 24th century, seventy-eight years after the existing Star Trek, although the exact timeframe had not yet been set in stone. The pilot had wording saying Data was part of the Starfleet "class of '78".^[5] The pilot episode, "Encounter at Farpoint", also has a cameo appearance by Leonard McCoy, who is said to be 137. The 24th century (Gregorian Calendar) comprises the years 2301-2400. ... Encounter at Farpoint was the first episode of Star Trek: The Next Generation. ... Dr. Leonard H. McCoy (nicknamed Bones), played by DeForest Kelley, is a character in the original Star Trek series, and the first six Star Trek films. ...

In the last episode of the first season, the year is firmly established by Data, as 2364.^[5] This implies McCoy was born around 2227, ruling out the Spaceflight Chronology-derived dating of the original series to the early 23rd century. Data[1] is a character, portrayed by Brent Spiner, in the Star Trek fictional universe. ...

A Star Trek Chronology was published in 1993, written by production staff members Denise Okuda and Mike Okuda.^[6] A second edition was issued in 1996.^[7] Okuda originally drew up a timeline for internal use by writers, based on his own research and assumptions provided by Richard Arnold. The dates in the Chronology are consistent with the earlier Star Trek: The Next Generation Technical Manual.^[8] An editor has expressed a concern that the subject of the article does not satisfy the notability guideline or one of the following guidelines for inclusion on Wikipedia: Biographies, Books, Companies, Fiction, Music, Neologisms, Numbers, Web content, or several proposals for new guidelines. ... Michael Okuda is an graphic designer who is best known for his work on Star Trek. ...

It gives the following dates:

• Zephram Cochrane invents warp drive around 2061 (in order that the SS Valiant can be constructed and go missing two hundred years before "Where No Man Has Gone Before", dated to 2265; the first edition gives 2061, the second edition moves this to 2063 per Star Trek: First Contact)
• the Romulan War takes place in the 2150s (approximately a hundred years before "Balance of Terror")
• the Federation is formed in 2161, after the Romulan War, on the basis that "Balance of Terror" says that it was an Earth-Romulan war, not a Federation-Romulan War
• the first Constitution class starship is launched in 2244, followed by the Enterprise in 2245
• Kirk's five year mission lasts from 2264 to 2269, based on the assumption that the original series is set exactly 300 years after its original broadcast.
  • aired live-action Star Trek episodes are dated from 2266 to 2269. The chronology does not include the events of Star Trek: The Animated Series
• the events of Star Trek: The Motion Picture take place in 2271 (Kirk has been Chief of Starfleet Operations for two-and-a-half years, according to dialog from Kirk and Decker)
• a second five-year mission takes place from 2271 to 2276 (speculation)
• the events of Star Trek II: The Wrath of Khan and Star Trek III: The Search for Spock take place in 2285
  • The Wrath of Khan is a sequel to the episode Space Seed, which Okuda dates to 2267. In Okuda's timeline there is a gap of eighteen years rather than the fifteen years established in dialog. The film was released in 1982, fifteen years after the episode's broadcast in 1967.
• the events of Star Trek IV: The Voyage Home take place in 2286
• the events of Star Trek V: The Final Frontier take place in 2287
• the events Star Trek VI: The Undiscovered Country take place in 2293, based on McCoy's statement that he had served on the Enterprise for 27 years, and his absence in "Where No Man Has Gone Before"
• Star Trek: Generations is set "78 years" before 2371, thus is set in 2293 and soon after Star Trek VI

The gap between 1986's Star Trek IV: the Voyage Home (2286) and the 1987 first season of The Next Generation (2364) is 78 years by this timeline, matching early press materials. In the fictional universe of Star Trek, the name Valiant was used by many starships, most of which are part of the Federation Starfleet. ...

Star Trek: Generations (Paramount Pictures, 1994, see also 1994 in film) is the seventh feature film based on the popular Star Trek science fiction television series. ...

There was a gap of 10 years between the broadcast of the last episode of TOS and the release of The Motion Picture. The film skirted round the fact the actors had aged, supposing that only two and a half years had passed since the events of the TV show. For Star Trek II, it was decided to acknowledge the reality of the ageing actors, both by setting the film some 15 years after "Space Seed", and by having Kirk worry about getting old.^[9]

Within the TNG era, episodes and films are easier to date. Stardates correspond exactly with seasons, with the first two digits of the stardate representing the season number. Okuda assumes the start of a season is January 1 and the end of the season is December 31.^[7] The Next Generation, Deep Space Nine, Voyager television series and movies have roughly followed "real time", and are set around 377 years after their release.

Since the Chronology was published, it has been generally adhered to by the producers of the show. The Voyager episode "Q2" establishes 2207 as the end of Kirk's five year mission. However, that date is clearly in error since Kirk had not yet been born. More than likely, the actor speaking the line misspoke, saying 2207 instead of 2270, when the 5-year mission actually ended. Q2 is an episode of the TV series Star Trek: Voyager, the 19th episode of the 7th season. ...

The film Star Trek: First Contact and prequel series Star Trek: Enterprise both revisit the early era. In First Contact, Zephram Cochrane is confirmed as having invented warp drive on Earth, but the date is moved forward slightly to 2063, and it is revealed that Earth's official first contact with an alien species, the Vulcans, took place immediately afterwards as a result of this. Star Trek: First Contact (Paramount Pictures, 1996; see also 1996 in film), is the eighth feature film based on the popular Star Trek science fiction television series. ... The starship Enterprise (NX-01) Star Trek: Enterprise is a science fiction television series set in the Star Trek universe. ...

Enterprise is set in the 2150s, and ties into the Cochrane backstory. The show uses the Gregorian calendar extensively, making dating easier. Its pilot, "Broken Bow", depicts first contact with the Klingons occurring much earlier than the Okuda chronology anticipated (it suggested a date of 2218, based on a line in "Day of the Dove", noting that dialog in First Contact makes this problematic). It shows the opening of the Romulan war and the start of a coalition between Earth, Vulcans, Andor and Tellar in the 2150s. The date of the founding year of the Federation, 2161, was revealed in the fifth-season TNG episode "The Outcast," based on an early draft of the Okuda timeline. The final episode of Enterprise, "These Are The Voyages...", is consistent with the establishment of 2161 as the founding year for the Federation. The Gregorian calendar is the most widely used calendar in the world. ... Broken Bow is the pilot episode (episode number 001 (Paramount Pictures, n. ... Day of the Dove is a third season episode of Star Trek: The Original Series, first broadcast November 1, 1968 and repeated June 17, 1969. ... First Contact is a fourth season episode of Star Trek: The Next Generation. ... These Are the Voyages. ...

No version of the Chronology or the Encyclopedia has been published since 1999. A 2006 book by Jeff Ayers contains a timeline which attempts to date all of the many Star Trek novels.^[10] This timeline has The Motion Picture in 2273, to account for the two-and-a-half-year gap between the end-date of 2270 established in "Q2" and the events of the movie. The official website, StarTrek.com, gives the date of that movie as 2271.^[11] The Star Trek franchise has produced a large number of novels, comic books, video games, and other materials, which are generally considered non-canon. ... Founded in November 1995, StarTrek. ...

Eugenics Wars and World War III

When the original series of Star Trek was produced, the 1990s were in the future, and so various elements of the backstory to Star Trek are set in that era, particularly the Eugenics Wars. The references to the Eugenics Wars and to a nuclear war in the 21st century are somewhat contradictory. The Eugenics Wars are a backstory event in the Star Trek fictional universe. ...

The episode "Space Seed" establishes the Eugenics Wars, and has them last from 1992 to 1996. Spock calls them "your last so-called World War", and McCoy identifies this with the Eugenics Wars. In the episode "Bread and Circuses" Spock gives a death toll for World War III of 37 million. The episode "The Savage Curtain" features a Colonel Green, who led a genocidal war in the 21st century. The TNG episode "Encounter at Farpoint" further establishes a "postatomic horror" on Earth in 2079. Space Seed is a first-season episode of Star Trek: The Original Series, that was first broadcast on February 16, 1967 and repeated on August 24, 1967. ... Bread and circuses has come to be a derogatory phrase that can criticize either government policies to pacify the citizenry, or the shallow, decadent desires of that same citizenry. ... The Savage Curtain a third season episode of Star Trek: The Original Series, is the antepenultimate series episode, first broadcast on March 7, 1969 and repeated July 1, 1969. ... Encounter at Farpoint was the first episode of Star Trek: The Next Generation. ...

The Star Trek Concordance identifies the "Bread and Circuses" figure as the death toll for a nuclear World War III, in the mid-21st century. Star Trek: First Contact firmly establishes World War III ended in a nuclear exchange in 2053, but with a body count of 600 million. The figure of Colonel Green is elaborated on in Star Trek: Enterprise. In the fictional Star Trek universe, World War III was a nuclear war that devastated much of Earth which took place during the mid-21st century. ... Star Trek: First Contact (Paramount Pictures, 1996; see also 1996 in film), is the eighth feature film based on the popular Star Trek science fiction television series. ... Colonel Green as portrayed by Phillip Pine Colonel Phillip Green is a character in the fictional Star Trek universe. ... The starship Enterprise (NX-01) Star Trek: Enterprise is a science fiction television series set in the Star Trek universe. ...

Although the back-story of Star Trek contains numerous minor elements that did not occur in history, the Eugenics Wars marked a substantial deviation. The Voyager episode "Future's End" saw the Voyager crew time-travel to Los Angeles in 1996, which, as the Encyclopedia notes, seems entirely unaffected by the Eugenics Wars, which ended that year. The episode acknowledges the issue only by featuring a model of Khan's DY-100-class ship on a 1996 desk. ^[12] Khan's spaceship is another anomaly for the timeline, which has a variety of long-lost spaceships being launched between 1980 and 2100, with inconsistent levels of technology (caused by the increasing real life time and also decreased optimism about the pace of space exploration). Futures End is a two-part episode from the third season of Star Trek: Voyager. ...

A reference in the Deep Space Nine episode "Doctor Bashir, I Presume?" suggests that the Eugenic Wars instead took place in the 22nd century. According to writer Ronald D. Moore, this was not an attempt at a retcon, but a mistake.^[13] Doctor Bashir, I Presume? features a familiar face from Star Trek: Voyager: Robert Picardo. ... For other persons named Ronald Moore, see Ronald Moore (disambiguation). ... This article or section does not cite its references or sources. ...

Greg Cox's non-canon two-book series The Eugenics Wars explains the Eugenics Wars in the context of real-life history by representing it as a secret history, and that the truth behind the various civil wars and conflicts in the 1990s was not generally known. Greg Cox is the New York Times bestselling author of numerous Star Trek novels, including The Eugenics Wars, (Volume One and Two), The Q Continuum, Assignment: Eternity, and The Black Shore. ... A secret history (or shadow history) is a revisionist interpretation of either fictional or real (or known) history which is claimed to have been deliberately suppressed or forgotten. ...

Cochrane

In the episode "Metamorphosis", it is stated that Zefram Cochrane of Alpha Centauri, the inventor of warp drive, disappeared 150 years ago, at the age of 87. Given Okuda's date of 2267 for that episode, this puts Cochrane's disappearance in 2117 and birth in 2030. 1980s spin-off material such as the Star Trek Spaceflight Chronology posit that Cochrane was from Alpha Centauri originally, and that a sub-warp ship the UNSS Icarus arrived at Alpha Centauri in 2048 to find he had discovered the theory behind warp drive. The Icarus then relayed its findings back to Earth, the first prototype warp ship was launched in 2055. Metamorphosis is a second season episode of Star Trek: The Original Series first broadcast November 10, 1967 and repeated July 19, 1968. ... Zefram Cochrane is a fictional character in the Star Trek universe created by Gene Roddenberry. ...

The Star Trek Chronology does not hold with this theory, and asserts that Cochrane was an Earth native, who moved to Alpha Centauri later in life. The first edition Chronology notes that Cochrane's invention of warp drive must have been at least 200 years before "Where No Man Has Gone Before", and suggests a date of 2061, noting that Cochrane would be 31 that year. Where no man has gone before is a saying used in the introductory sequence of all but one of the episodes of the original Star Trek science fiction television series. ...

The movie Star Trek: First Contact prominently features Cochrane's first warp attempt. The film is set in 2063, two years after the Chronology suggestions, and therefore by the timeline Cochrane is 33. The actor who played Cochrane in that movie, James Cromwell, was 56 at the time of the film's release. The Encyclopedia notes the age issue, and claims that the Cromwell Cochrane had suffered from radiation poisoning, causing his aged appearance.

Ordering of episodes

The production order of original series episodes differered greatly from the original broadcast order. The Chronology assumes the correct chronological order is production order. Episodes of the original series tend to be largely standalone and rarely make references to other episodes.^[7]

For later series, the Chronology follows this model, except for obvious exceptions, such as "Symbiosis", an episode shot after Tasha Yar's death in "Skin of Evil" had been filmed, but featuring her. After the debut of DS9 (and therefore the start of a period where there were two ongoing series of Star Trek), the Chronology instead adopts ordering by airdates. The latest edition of the Chronology was published in 1996, and thus does not cover Star Trek episodes or films released after then. Symbiosis is a first season episode of Star Trek: The Next Generation, first broadcast April 18, 1988. ... Lieutenant Natasha Yar, played by Denise Crosby, is a Starfleet officer in the fictional Star Trek universe. ... Skin of Evil is a first season episode of Star Trek: The Next Generation, first broadcast April 25, 1988. ...
