2267 to 2268
Table of Contents

2267: S.D. (4)30d8 to (4)40d2

Doctor Coleman has been in charge of medical arrangements for Janice Lester’s team for “two years” by November 2269 and TOS “Turnabout Intruder”. Perhaps this is from the beginning of the Camus II mission, which would start sometime late in this year or very early in 2268, if so.

Friday 4th January, 2267: S.D. (4)31a1

Enterprise undergoes routine maintenance at the planet Cygnet XIV. The facility may also be known as Starbase 200. It’s just before TOS “Tomorrow is Yesterday”, and Starbase 200 is where the ship’s going in TOS “The Alternative Factor”.
Comment: The timings are a bit tight here, but I decided to stick with it. Unless things were rushed, how did those naughty women reprogram the computer without Spock and Scotty spotting and fixing it?

TOS “Tomorrow is Yesterday”

Sunday 6th January, 2267: S.D. (4)31a3

Estimated duration: A day
Chronology: Unusually, the chronometer appears to be generating stardates while they’re trapped in the past, covering two days, S.D. 3113.2 and S.D. 3114.1. I’ve assumed that Spock guides them back to the exact day they left. The main events are in 1969.
Continuity: If you’re wondering why the Guardian of Forever isn’t signalling again, I’m assuming that the Federation already has a team of historians and scientists working with it.

Early January 2267

Enterprise travels to Starbase 9, its destination in TOS “Tomorrow is Yesterday”. The computer is repaired, since the “personality” only appears in that one story.

TOS “Return of the Archons”

Saturday 19th to Monday 21st January, 2267: S.D. (4)31b6 to (4)31b8

Estimated duration: 3 days
Chronology:There are dates for all three days, S.D. 3156.2, S.D. 3157.4and S.D. 3158.7.
Continuity: The USS Archon was lost at Beta III 100 years before.

TOS “Space Seed”

Thursday 24th to Saturday 26th January, 2267: S.D. (4)31c1 to (4)31c3

Estimated duration: 3 days
Chronology:There are stardates for three days, S.D. 3141.9, S.D. 3142.8 and S.D. 3143.3.
Continuity: It is two centuries after 1996. The actual length of time is 271 years. Assuming that “1996” refers to 2053 C.E., then it would be 214 years. Mister Chekov doesn’t appear in this story, or indeed any story until the second season of “Star Trek”, although the stardates do suggest he might have been on the ship before this. It isn’t essential that he’s here, since I have him meeting Khan on Ceti Alpha V much later.

TOS “A Taste of Armageddon”

Monday 4th to Tuesday 5th February, 2267: S.D. (4)31d2 to (3)31d3

Estimated duration 2 days
Chronology: There are log entries for two days, S.D. 3192.5 and S.D. 3193.0.
Continuity: It’s 50 years since Valiant was destroyed. Enterprise is travelling to Argona II after this story, but is evidently diverted to Janus VI instead. Captain Kirk refers to the events of this story in TOS “By Any Other Name”.

Wednesday 6th February, 2267: S.D. (4)31d4

“Schmitter. Like the rest of them. Burned to a crisp!” Two days before Enterprise arrives at Janus VI in TOS “Devil in the Dark”.

TOS “Devil in the Dark”

Friday 8th to Saturday 9th February, 2267: S.D. (4)31d6 to (4)31d7

Estimated duration: 2 days
Chronology: There’s a log entry for the first day, S.D. 3196.1.
Continuity: Sulu recalls this story in TOS “That Which Survives”.

TOS “Errand of Mercy”

Sunday 10th to Friday 15th February, 2267; 27th to 32nd maqtaH, 930 Q.B.: S.D. (4)31d8 to (4)32a3

Estimated duration: 6 days
Chronology: There is a log entry on the first day, S.D. 3198.4 and the fourth, S.D. 3201.7.
Continuity: This is the first of many appearances by the Klingons, and Kor himself will be returning in “Star Trek: Deep Space Nine”. It’s three years before TOS “Day of the Dove” (I have that in July 2269, so it’s a remarkably short three years, more like two years and five months). TOS “A Taste of Armageddon”, TOS “Devil in the Dark” and this story are all remarkably close together. It’s a problem with the stardates themselves, so I’ve done my best.

Thursday 21st to Friday 22nd February, 2267: S.D. (4)32a9 to (4)32b0

The stardate placement of TOS “Metamorphosis”.

March 2267: S.D. (4)32b7 to (4)33x7

Nearly a year before TOS “A Private Little War” (February 2268), “firesticks” first appear on Neural.

Saturday 23rd to Monday 25th February, 2267: S.D. (4)32b1 to (4)32b3

TOS “The Gamesters of Triskelion” would fall here by stardate, although there would still be problems with the dates given in the story.

TOS “This Side of Paradise”

Friday 1st March, 2267: S.D. (4)32b7

Actual dates: Tuesday 30th April, 2267: S.D. (4)34a7

Estimated duration: 1 day
Chronology: The stardate for this story is far too late for my purposes S.D. 3417 (with entries for 3417.3, 3417.5 and 3417.7). I’ve moved it forward, arbitrarily. Although everything we see seems to happen in just one day, the colony will have to be packed up, and the colonists transported to Starbase 27 afterwards.
Continuity: Spock knew Leila Kalomi on Earth, six years ago.

TOS “Operation: Annihilate!”

Monday 11th to Wednesday 13th March, 2267: S.D. (4)32c7 to (4)32c9

Estimated duration: 3 days
Chronology: There are stardates for the first and third days, S.D. 3287.2 and S.D. 3289.8.
Continuity: James Kirk’s older brother “Sam” dies. Although TOS “What Are Little Girls Made Of?” says “Sam” has three children, we only see one.

Mid-March, 2267

Enterprise travels to Starbase 10. Regardless of the number of siblings he has, little Peter Kirk is now an orphan, so presumably he gets packed off to the Space Orphanage, at the first opportunity after TOS “Operation: Annihilate!” It’s the gap between the first and second seasons of “Star Trek”.

TOS “Catspaw”

Monday 1st April, 2367: S.D. (4)33x8

Actual date: Sunday 2nd December, 2266: S.D. (4)30a8

Chronology: A stardate is given, but it’s far too early for my theories, S.D. 3018.2. I’ve therefore moved it to the start of the second season stories. It’s Mister Chekov’s first story, and I've fixed my timeline so that “Star Trek II: The Wrath of Khan” doesn't force Chekov to be on the ship by TOS “Space Seed”.
Continuity: This episode was made and originally broadcast as a “Halloween” story. Unfortunately, the stardates don’t support a Halloween date, and even if I cheat, Halloween 2266 is too early for me (although that might not be the case for you), and Halloween 2267 is really implausibly late, particularly for Mister Chekov’s introduction.

TOS “Metamorphosis”

Tuesday 2nd to Wednesday 3rd April, 2267: S.D. (4)33x9 to (4)33y0

Actual dates: Thursday 21st to Friday 22nd February, 2267: S.D. (4)32a9 to (4)32b0

Estimated duration: 2 days
Chronology: Once again, the stardates in this story are too early to suit my purposes. 3219.8 and 3220.3. I’ve arbitrarily shifted the story to a later time, so that it’s in with the other second season shows.
Continuity: Zephram Cochrane of Alpha Centauri, discoverer of warp drive, will appear again in “Star Trek: First Contact”, and ENT “Broken Bow”. He vanished about 150 years ago, at the age of 87. This creates some problems in the timeline, so see The Cochrane Chronology Conundrum for my attempt at a solution.

Friday 12th April, 2267: S.D. (4)33y9

Mr. Spock stops eating, three days before TOS “Amok Time”.

TOS “Amok Time”

Monday 15th to Thursday 18th April, 2267; 3rd to 5th D’ruh, 8902 V.E.: S.D. (4)33z2 to (4)33z5

Estimated duration: 4 days
Chronology: There’s a log entry for the first day, S.D. 3372.7. How much later they arrive at Vulcan is anyone’s guess, other than it’s less than eight days (or Spock would have died). I’ve assumed three days.
Continuity: Although they’re collected from Vulcan not long after this, in TOS “Journey to Babel”, Spock’s parents don’t appear. Enterprise still visits Altair after the end of the story. T’Pau will appear (when she was much younger) in “Star Trek: Enterprise”.
Comment: By my calculations, T’Pau is 145 Earth years old when we see her here. She’s not aged well, when you compare her appearance with Tuvok’s.

Tuesday 23rd April, 2267: S.D. (4)34a0

Enterprise shows the flag at Altair, after TOS “Amok Time”

Tuesday 30th April, 2267: S.D. (4)34a7

This is where TOS “This Side of Paradise” would fall, by strict stardate.

TOS “Who Mourns for Adonais?”

Saturday 11th May, 2367: S.D. (4)34b8

Estimated duration: 1 day
Chronology: There is a log entry, S.D. 3468.1.
Continuity: Mister Chekov tells Captain Kirk he’s 22, suggesting he was born sometime between May 2244 and April 2245.
Comment: Doctor McCoy’s rather crass comment at the start of the show that an attractive woman like Carolyn Palamas will be leaving Starfleet to have a family, was meant to set up the revelation that she’d fallen pregnant during the story. That element was cut from the broadcast version, although it stayed in the James Blish adaptation. Whether Carolyn is enceinte after meeting Apollo (or not) is entirely up to you.

TOS “The Deadly Years”

Tuesday 21st to Friday 24th May, 2267: S.D. (4)34c8 to (4)34d1

Estimated duration: 4 days
Chronology: The stardates for this story are a bit odd, S.D. 3478.2 and S.D. 3579.4. The second is easily explained as a mistake, for S.D. 3479.4, since Captain Kirk is having trouble remembering numbers in the short term.
Continuity: James Kirk is 34, consistent with him being born in January 2233 (as established in the 2009 film and “Star Trek Beyond”). Enterprise will presumably drop Commodore Stocker off at Starbase 10. Doctor Janet Wallace is another ex-girlfriend of Kirk’s. Like Areel Shaw, she’s been keeping count; it’s six years, four months and that same “odd number of days” since she was dumped.
Comment: Obviously, Doctor McCoy’s cure only reverses the effects of the radiation, not actual ageing, otherwise everyone would stay young from now on.

TOS “Friday’s Child”

Thursday 30th May to Wednesday 5th June, 2267; 33rd to 39th So’jen, 930 Q.B.: S.D. (4)34d7 to (4)35x3

Estimated duration: A week
Chronology: There are log entries on the first, second and third days. S.D. 3497.2, S.D. 3498.9and S.D. 3499.1. Since there has to be a treaty arranged, I’ve assumed that Enterprise stays at Capella IV for at least a week, all told.
Continuity: Some time before this story, Doctor McCoy spent several months on Capella IV.

TOS “The Changeling”

Thursday 13th June, 2267: S.D. (4)35y1

Estimated duration: 1 day
Chronology: There is a log entry, S.D. 3541.9.
Continuity: There must be at least a week afterwards, for Uhura to be re-educated.

Early July 2267

Just before TOS “Wolf in the Fold” Scotty is injured in an accident caused by a woman.

TOS “Wolf in the Fold”

Saturday 6th to Sunday 7th July, 2267: S.D. (4)36a4 to (4)36a5

Estimated duration: 2 days
Chronology: There are log entries covering both days, S.D. 3614.9 and S.D. 3615.4.

TOS “Obsession”

Sunday 21st to Wednesday 24th July, 2267: S.D. (4)36b9 to (4)36c2

Estimated duration: 4 days
Chronology: There are log entries for the first two days, S.D. 3619 (entries for 3619.2 and 3619.6) and S.D. 3620.7. I’ve calculated that the delayed rendezvous with Yorktown will be on the fourth day.
Continuity: Ensign Garrovick is the son of the Captain Garrovick James Kirk served under from leaving the Academy to the unfortunate incident on Farragut eleven years before.
Comment: According to the dialogue, Enterprise covers well over 1,000 light-years during this story. That’s an awful lot.

TOS “The Apple”

Friday 16th to Saturday 17th August, 2267: S.D. (4)37x5 to (4)37x6

Estimated duration: 2 days
Chronology: There are log entries on the first day, S.D. 3715, for 3715.3 and 3715.6.

Week of Thursday 22nd to Wednesday 28th August, 2267: S.D. (4)37y1 to (4)37y7

The week before TOS “Mirror, Mirror”, Marlena Moreau joins the crew of Enterprise.

TOS “Mirror, Mirror”

Thursday 29th to Friday 30th August, 2267: S.D. (4)37y8 to (4)37y9

Estimated duration: 2 days
Chronology: The amount of time is very limited, definitely less than twelve hours. I’ve assumed the story runs from evening to the early morning of the next day.
Continuity: This is the first visit to the Mirror Universe, which will be visited again in “Star Trek: Deep Space Nine” and shown in ENT “In a Mirror, Darkly”.

In the Mirror Universe, the Federation is a savage Earth Empire.

Following TOS “Mirror, Mirror”, the alternate Spock attempts to reform the Empire, but leaves it open to conquest by the Cardassians and Klingons, as is explained in DS9 “Crossover”.

Thursday 19th September, 2267: S.D. (4)38a9

Enterprise begins collecting delegates for the Babel Conference, three days before TOS “Journey to Babel”.

TOS “Journey to Babel”

Sunday 22nd to Monday 23rd September, 2267; 18th to 19th Khuti, 8902 V.E.: S.D. (4)38b2 to (4)38b3

Estimated duration: 2 days
Chronology: There are log entries for both days, S.D. 3842 (3842.3 and 3842.4) and S.D. 3843.4.
Continuity: Sarek helpfully tells us he’s 102.437 Earth years old. It’s also the first appearances by the Andorians and the Tellarites. They’ll crop up as background characters in several stories, before taking a more major role in the events of “Star Trek: Enterprise”.

Wednesday 25th September, 2267: S.D. (4)38b5

Two days after TOS “Journey to Babel”, Captain Kirk should be well enough to leave Sickbay.

Monday 30th September, 2267: S.D. (4)38c0

Orion neutrality is questioned at the Babel Conference on S.D. 3850.5, according to TAS “The Pirates of Orion”.
Comment: Since I’m ignoring the animated shows, mainly because I can’t fit them in, this might not have happened. There’s nothing to say it didn’t, though.

Early October 2267

The Babel Conference decides to admit Coridan to the Federation, but we have to wait until TNG “Sarek” to find that out.

Sunday 6th October, 2267: S.D. (4)38c6

Assuming Doctor McCoy is accurate when he says it’ll be two weeks until things are back to normal, the last delegates for the Babel Conference will have been dropped off, a fortnight after the start of TOS “Journey to Babel”.

Sunday 8th December, 2267: S.D. (4)40a9

The day before TOS “Bread and Circuses”, the last of the SS Beagle “barbarians”, William B. Harrison, dies in the arena.

TOS “Bread and Circuses”

Monday 9th to Tuesday 10th December, 2267: S.D. (4)40b0 to (4)40b1; ante diem v to ante diem iv Idus Decembres MMMXX A.U.C.

Estimated duration: 2 days
Chronology: There are stardates for both days, S.D. 4040 (with entries for 4040.7 and 4040.9) and S.D. 4041 (4041.2 and 4041.7).
Continuity: R.M. Merrick was dropped from the Academy in his fifth year.
Comment: Doctor McCoy says there were no Sun worshippers in Ancient Rome. This is incorrect. The cult of Sol Invictus became an official religion in the Roman Empire by declaration of the Emperor Aurelian in 274, and Augustine preached specifically against it in the 5th century.

Before 2268

The ruins on Tagus III are sealed off, over a century before TNG “Qpid”.

The people of Kaelon II start work on helium fusion enhancement, over a century before TNG “Half a Life”.

2268: S.D. (4)40d3 to (4)50d8

The Polaric Test Ban Treaty comes into force this year, following a near-tragedy on the Romulan world of Chaltok IV, according to VOY “Time and Again”.

January 2268; 42nd tlha’laH to 20th do’qat, 930 Q.B.: S.D. (4)40d3 to (4)41z3

The Klingon ship Gr’oth begins its mission, five months before TOS “The Trouble with Tribbles” (June 2268), with the ship name taken from DS9 “Trials and Tribble-ations”.

February or March 2268: S.D. (4)41z4 to (4)43y3

Cyrano Jones is operating in the Klingon sphere of influence, less than four months before TOS “The Trouble with Tribbles” (June 2268).

Six months before TOS “Patterns of Force” (late August 2268), contact is lost with John Gill on the planet Ekos.

Sunday 9th February, 2268: S.D. (4)42a2

On S.D. 4202.1, the day before TOS “The Doomsday Machine”, Constellation investigates some odd occurrences in system L-374.

TOS “The Doomsday Machine”

Monday 10th February, 2268: S.D. (4)42a3

Estimated duration: A day
Chronology: Enterprise arrives at the scene shortly after Constellation is destroyed, so I can’t see it being any later than the next day. All the action seems to take place over the space of a single day, but Scotty will have to fix the engines afterwards.
Continuity: According to background information, Commodore Matt Decker is the father of Willard Decker, who appears in “Star Trek: The Motion Picture”.

TOS “A Private Little War”

Tuesday 18th to Wednesday 19th February, 2268; 38th to 39th do’qat, 930 Q.B.: S.D. (4)42b1 to (4)42b2

Estimated duration: 2 days
Chronology: There is a stardate for the first day S.D. 4211, with entries for 4211.4 and 4211.8. We only see another day after, but presumably Enterprise will remain longer, at least for another day or two.
Continuity: Lieutenant James Kirk led the first survey of the planet Neural.

TOS “The Gamesters of Triskelion”

Saturday 7th to Monday 9th March, 2268: S.D. (4)42c9 to 42d1

Actual dates: Saturday 23rd to Monday 25th February, 2267: S.D. (4)32b1 to (4)32b3

Estimated duration: 3 days
Chronology: A nightmare. The first day has stardates for S.D. 3211 (3211.7 and 3211.8), but also specifies that around two hours later it’s S.D. 3259.2. Both these stardates are far too early to suit me, so I’ve arbitrarily moved the story to here. I’ve guessed at three days, but since Enterprise only has to go 11.63 light-years to find the missing landing party, it might only be two.

TOS “The Immunity Syndrome”

Wednesday 25th to Friday 27th March, 2268: S.D. (4)43x7 to (4)43x9

Estimated duration: 3 days
Chronology:There are stardates for all three days. S.D. 4307.1, S.D. 4308.8 and S.D. 4309, with entries for 4309.2 and 4309.4.
Continuity: Intrepid, with an all-Vulcan crew, is completely destroyed on the first day of the story.

April 2268: S.D. (4)43y4 to (4)44b3

Just after TOS “The Immunity Syndrome”, Enterprise is due to visit Starbase 6.

Thursday 2nd April, 2268: S.D. (4)43y5

The strict stardate placement of TOS “Spectre of the Gun”.

32nd QuSten, 930 Q.B.; Friday 3rd April, 2268: S.D. (4)43y6

On S.D. 4326.3, according to his file, General Korrd is placed in command of the Shepard Sector. He’s later held responsible for the “Feine Incident”, where Klingon bases were overrun by the Orions, according to a screen display in “Star Trek V: The Final Frontier”. My system would allow this to happen on any one of several different dates, but I’ve assumed that it was meant to be contemporary with the original five-year mission.

Thursday 9th to Wednesday 15th April, 2368: S.D. (4)43z2 to (4)43z8

TOS “Elaan of Troyius”, by stardate.

May 2268: S.D. (4)44b4 to (4)45x4

The month before TOS “A Piece of the Action” (June 2268), Starfleet finally gets the message sent by Horizon a century earlier.

Saturday 23rd May, 2268: S.D. (4)44d6

Norman arrives on the Enterprise, 72 hours before TOS “I, Mudd”.

TOS “I, Mudd”

Tuesday 26th May to Monday 1st June, 2268: S.D. (4)44d9 to (4)45x5

Estimated duration: A week
Chronology: There is a log entry, S.D. 4513.3. It must be the fifth day, because it takes four days at maximum warp to reach the planet after Norman hijacks the ship.
Continuity: Mister Chekov has no idea who Harry Mudd is, and Sulu has to explain.

Mid June 2268

The week before TOS “The Trouble with Tribbles”, Enterprise makes a rendezvous with Lexington and Lieutenant Whatley joins the ship, according to DS9 “Trials and Tribble-ations”.

TOS “The Trouble with Tribbles” & DS9 “Trials and Tribble-ations”

Friday 19th to Sunday 21st June, 2268; 5th to 7th jo’voS, 931 Q.B.: S.D. (4)45z3 to (4)45z5

Estimated duration: 3 days
Chronology: There are stardates for all three days. S.D. 4523.3, S.D. 4524.2 and S.D. 4525.6. Mister Spock confirms the number of days when he suggests the tribbles have been in the grain store for three days. Unfortunately, DS9 “Trials and Tribble-ations” suggests that events unfold over eighteen hours from S.D. 4523.7, taking the time to S.D. 4524.5 at the latest by my calculations. TOS “The Trouble with Tribbles” is equally clear that the tribbles aren’t found in the grain until after S.D. 4525.6. I prefer the longer timescale, but you’re not forced to. Lieutenant Whatley is due for her physical at 15:00 on Saturday the 27th, S.D. 4524.6.
Continuity: It’s a Friday, 105 years, 1 month and 12 days before the “contemporary” part of DS9 “Trials and Tribble-ations” when Defiant arrives at S.D. 4523.7. Captain Koloth will also appear in DS9 “Blood Oath”.

TOS “A Piece of the Action”

Wednesday 24th to Thursday 25th June, 2268: S.D. (4)45z8 to (4)45z9

Estimated duration: 2 days
Chronology: “The Star Trek Concordance” dates this story to S.D. 4598.0.
Continuity: Horizon visited 100 years earlier. According to dialogue, it was before the development of subspace radio.

July 2268: S.D. (4)46a5 to (4)46d5

Six months before TOS “The Empath” (January 2269), the Federation establishes a research outpost in the Minara system.

TOS “By Any Other Name”

Thursday 23rd to Monday 27th July, 2268: S.D. (4)46c7 to (4)46d1

Estimated duration: 5 days
Chronology: There are log entries on the first two days, S.D. 4657.5 and S.D. 4658.9. How long things take after that is anyone’s guess. I’ve assumed another three days for driving the Kelvans crazy and taking them back to the planet they were on at the start.
Continuity: Mister Spock’s failed escape attempt is based explicitly on the one in TOS “A Taste of Armageddon”.

TOS “The Ultimate Computer”

Wednesday 12th to Tuesday 18th August, 2268: S.D. (4)47x7 to (4)47y3

Estimated duration: A week
Chronology: I’ve assumed that the log entries are on the third day, S.D. 4729.4 and the fifth S.D. 4731.3.

TOS “Return to Tomorrow”

Sunday 23rd to Tuesday 25th August, 2268: S.D. (4)47y8 to (4)47z0

Estimated duration: 3 days
Chronology: There are log entries for all three days, S.D. 4768.3, S.D. 4769.1 and S.D. 4770.3.
Comment: All the Arretans die, but what becomes of the super-advanced robot they were building? Incidentally “Arret” comes from the script. The name of the planet doesn’t appear anywhere in the broadcast story.

Around Saturday 29th August, 2268: S.D. (4)47z4

A week before TOS “The Omega Glory”, Ron Tracey uses his phaser to kill several hundred Yangs on Omega IV.

TOS “Patterns of Force”

Sunday 30th to Monday 31st August, 2268: S.D. (4)47z5 to (4)47z6

Estimated duration: 2 days
Chronology: Everything seems to happen on one day, but I’ve made it two, to be on the safe side. The stardate often associated with this story: 2534.0, doesn’t actually appear in it, luckily for me.
Continuity: John Gill was Kirk’s instructor at the Academy, but not Spock’s.
Comment: As they say in the story (although I’m paraphrasing a bit), how could a professional historian ever be so monumentally stupid as to think that Nazis would be a good idea?

TOS “The Omega Glory”.

Saturday 5th to Sunday 6th September, 2268: S.D. (4)48a1 to (4)48a2

Estimated duration: 2 days

TOS “Assignment: Earth”

Friday 11th September, 2268: S.D. (4)48a7

Estimated duration: A day
Chronology: Everything we see is in the year 1968, which is where the main entry for the story is.

Mid-September, 2268

I’m assuming that Enterprise goes for a minor refit around now. Certainly the crew stop wearing their velour uniforms and get “shiny” shirts instead. It’s the change from the second to the third season of “Star Trek”.

October 2268: S.D. (4)48c7 to (4)49b7

The events viewed by the landing party on tape in TOS “The Empath” (January 2269) take place, three months before. The Federation team on Minara disappear.

TOS “The Paradise Syndrome”

Saturday 26th September to Wednesday 25th November, 2268: S.D. (4)48c2 to (4)50a2

Estimated duration: 61 days
Chronology:There are log entries for the first two days, S.D. 4842.6 and S.D. 4843.6. From that day, it will take 59.223 days to return and find Captain Kirk, leading to my guess of 61 days altogether.
Continuity: The Preservers are introduced as one possible explanation for the “parallel Earths.” Enterprise will need some repairs afterwards.
Comment: There are over 400 people on Enterprise. Couldn’t some of them have stayed behind to find their captain?

Tuesday 8th to Monday 21st December, 2268: S.D. (4)50b5 to (4)50c8

The Starnes expedition on Triacus makes a series of reports. The entries are dated S.D. 5025.3, S.D. 5032.4 and S.D. 5038.3, which I calculate is the day before TOS “And the Children Shall Lead” starts, and which seems to match the continuity of the story.

TOS “The Enterprise Incident”

Thursday 10th December, 2268: S.D. (4)50b7

Estimated duration: 1 day
Chronology: There are log entries for S.D. 5027, at 5027.3 and 5027.4.
Continuity: The Federation acquires a Romulan cloaking device, and discovers that the Romulans are using Klingon spacecraft.

TOS “And the Children Shall Lead”

Tuesday 22nd to Wednesday 23rd December, 2268: S.D. (4)50c9 to (4)50d0

Estimated duration: 2 days
Chronology: There’s a log entry for the first day, S.D. 5029.5. From context, it has to be very soon after the last report by the Starnes expedition, so it ended up being a really major clue for me of how stardates might be made to work.
Continuity: Since we never see any of them again, the children must all have been dropped off at Starbase 4 afterwards.
