What to Make of TOS Season One Stardates.
So what would someone think about the stardates in Season One of TOS, if they recorded them all and figured out how much time passed between stardates in different episodes?
If they believed that TOS episodes happened in original broadcast order they would see that stardates sometimes decreased in value as well as increasing in value. So if they assumed that episodes happened in an average separation in time, such as one week or two weeks or three weeks or four weeks apart, they could plot the value of stardates over time.
They could also plot the value of hour many hours per stardate there were at various times. They could convert each figure to stardate units or fractions of them per hour. Thus they could plot how rapidly or slowly stardates increased and sometimes decreased over time.
And they would hope that the two graphs would produce curves that agreed with each other.
Thus they might deduce that stardates represented the strength of some factor that varied over time. That factor could be the strength of a factor that multiplied or divided warp speeds, making ships travel faster or slower than they normally would at their warp factors.
Thus a higher stardate might indicate a faster speed and a shorter voyage time, or maybe a higher stardate might indicate a longer voyage time and a slower speed.
So they could have tried plotting stardates against the speeds of voyages in various episodes where those speeds could be calculated and the stated warp factors of those voyages to see how well they correlated.
And if that hypothetical viewer had thought that the episodes might possibly happen in production order, once they found out what the production order was, they could have tried plotting the first season of TOS stardates against the production order to see how well they correlated.
Or that hypothetical fan might have assumed that TOS season one episodes happened in production order. Thus they would assume that the stardates got higher with each successive episode. However, the ratio of hours per stardate unit, or of stardate units per hour, would change over time, so there would still be a curve to be graphed.
Or maybe they might assume that too much happens in TOS to all happen in one timeline. Maybe they would decide that almost every episode happens in an alternate universe from the other episodes, with the exception of episodes that are clearly sequels to other episodes.
So they might explain the differing lengths of stardate units by assuming that Starfleet adopts different stardate systems in different alternate universes, with different ratios of stardate units to time.
They might assume that a stardate unit equaled a day, a 24 hour period, and thus that a stardate unit equaled 24 hours. But they might also assume that a stardate unit equaled a duty watch period aboard ship. There might be two, three, or four watches per 24 hour day, and so possibly a stardate unit equaled 12, 8, or 6 hours.
In "The Conscience of the King" several scenes happen during, one, two, or three night periods aboard the
Enterprise. Captain Kirk gives Lenore Karidian a tour of the ship, and on the observation deck:
LENORE: Did you order the soft lights especially for the occasion?
KIRK: If I had ordered soft lights, I'd also have arranged for music and flowers. Unfortunately, it isn't so. On the Enterprise, we try to duplicate earth conditions of night and day as closely as possible.
in a later scene, Lt. Kevin Riley is on duty alone in the engine room, probably during a night period.

(There's just one officer on duty, and he hasn't touched the meal lying on a plate nearby)
RILEY: Hey. Rec room. Somebody.
In a third scene, the Karidian players perform
Hamlet for the crew.
[Ship's Theatre]
LENORE: (on stage) Tonight, the Karidian Players present Hamlet, another in a series of living plays presented in space, dedicated to the tradition of classic theatre. Hamlet is a violent play about violent times when life was cheap and ambition was God.
So if they turn the lights up and down in public spaces to mimic the daily cycle on Earth, they don't have to mimic it precisely. Humans could probably adjust quite well to a daily cycle which was between 23.0 and 25.0 hours long instead of exactly 24.0 hours long.
So if a stardate unit is equal a a watch that is one quarter of a 23.0 to 25.0 hour ship's day, the stardate unit would be equal to 5.75 to 6.25 Earth hours; if the watch is equal to a third of a ship's day the watch could be equal to 7.666 to 8.333 Earth hours; if the watch is equal to half a ship's day, the watch could be equal to 11.5 to 12.5 Earth hours; if the watch is equal to a full ship's day it would equal 23.0 to 25.0 Earth hours.
And if humans could function well with a ship's day somewhere between 22.0 and 26.0 hours, a watch a quarter of a ship's day would be between 5.5 and 6.5 Earth hours; a watch a third of ship's day would between 7.333 and 8.666 Earth hours; a watch half a ship's day would be between 11.0 and 13.0 Earth hours; and a full ship's day would be between 22.0 and 26.0 hours.
So maybe we can try fitting the various lengths of stardate units into 5.5 to 6.5 Earth hours, 7.333 to 8.666 Earth horse, 11.0 to 13.0 Earth hours, or 22.0 to 26.0 Earth hours.
"Errand of Mercy" seems to have much shorter stardate units, 1.51 to 6.06 minutes, than any such range.
In "Mudd's Women" there might be 2.0 to 2.22 hours in a stardate unit, or possibly more.
In "The Squire of Gothos" there might be 5.0 hours in a stardate unit, which almost makes it to 5.5.
Episodes with Stardate lengths consistent with 5.5 to 6.5 Earth hours include: "The Enemy Within", "Mudd's Women", "The Conscience of the King", "Shore Leave", "The Return of the Archons", "The Alternative Factor", and "Operation - Annihilate!".
Episodes with stardate lengths consistent with 7.333 to 8.666 Earth hours include: "The Enemy Within", "Mudd's Women", "The Conscience of the King", "Shore Leave", "Tomorrow is Yesterday", "The Return of the Archons", "The Alternative Factor", and "Operation - Annihilate!".
Episodes with stardate lengths consistent with 11.0 to 13.0 Earth hours include: "Where No Man Has Gone Before:, "The Naked Time", "The Enemy Within", "Mudd's Women", "The Menagerie", "The Conscience of the King", "Tomorrow is Yesterday", "The Return of the Archons", "Space seed", "This Side of Paradise", "The Alternative Factor", and possibly "Operation - Annihilate!".
Episodes with stardate lengths consistent with 22.0 to 26.0 Earth hours include: "Where No Man Has Gone Before:, "The Naked Time", "Mudd's Women", "Miri", "Dagger of the Mind", "The Conscience of the King", "Shore Leave", "The Galileo 7", "Court Martial", "The Return of the Archons", "Space seed", "This Side of Paradise", "The Alternative Factor", and possibly "Operation - Annihilate!".
There should be fewer than 68.6 Earth hours in a stardate unit in "the Man Trap", fewer than 47.38 hours in "Balance of Terror", fewer than 48 Earth hours in "A Taste of Armageddon", making each of them consistent with each of the ranges of 5.5 to 6.5 Earth hours, 7.333 to 8.666 Earth horse, 11.0 to 13.0 Earth hours, or 22.0 to 26.0 Earth hours.
The stardate length of 14.1666 Earth hours from "The Squire of Gothos" doesn't fit in any of those ranges. But a stardate length of about 5 hours is also calculated from "The Squire of Gothos" Finding a way to the two calculations to agree may eliminate the 14.1666 hour figure.
The stardate length of about 5 hours from "The Squire of Gothos" is much more precise than most of the length ranges from episodes. It almost reaches to the 5.5 to 6.5 hour range. if a ship's day could be between 20.0 and 28.0 Earth hours, 5 hours could fit in with a quarter day watch. Thus a stardate unit about 5 hours long would fit in with "The Naked Time", "The Enemy Within", "Mudd's Women", "Shore Leave", "The Return of the Archons", "The Alternative Factor", and "Operation - Annihilate!".
The stardate length of about 11.25 hours from "The Corbomite Maneuver" would be consistent with: "Charlie X", "Where No Man Has Gone Before", "The Naked Time", "The Enemy Within", "The Conscience of the King", "Shore Leave", "Tomorrow is Yesterday", "The Return of the Archons", "Space seed", "This Side of Paradise", "The Alternative Factor", and possibly "Operation - Annihilate!" and possibly with "Mudd's Women" with some stretching.
The stardate length of about 22.8 Earth hours from "The Galileo 7" is consistent with "Where No Man Has Gone Before:, "The Naked Time", "Mudd's Women", "Dagger of the Mind", "The Menagerie", "The Galileo 7", "Court Martial", "The Return of the Archons", "Space seed", "This Side of Paradise", "and The Alternative Factor".
"The Man Trap", "Balance of Terror", and a "A Taste of Armageddon" would be consistent with any of the 5 hour, 11.25 , or 22.8 hour lengths.
And stardate lengths can not be calculated for "What are little Girls Made of?", "Arena", "The Devil in the Dark", and "The City on the Edge of Forever".
So that leaves only "Errand of Mercy" with stardate units which at first sight appear to be only minutes long, And "Miri", with stardate units at least 23.9 hours long, as episode which seem to be inconsistent with stardate units being either about 5 hours long, or about 11.25 hours long, or about 22.8 hours long.
I note that 11.25 hours is half of 22.50 hours, and 22.8 hours is twice 11.4 hours, so possibly there is a ships's day about 22.5 to 22.8 hours long, and a half day watch about 11.25 to 11.4 hours long. And possibly "Miri" is in an alternate universe where a ship's day is set about at least 23.9 hours. And possibly the stardate unit of about 5 hours is equal to a watch that is one fifth of a 25 hour ship's day.
So it seems to be possible to have no more than 5 stardate systems in the first season of TOS, no doubt adopted in various alternate universes, and the majority of episodes would fit in no more than three stardate systems.
