I know that I seriously neglected this thread I started, but would just like to remind everyone that I posted it in the TOS section to
specifically discuss stardates of the TOS series and TOS movies because I feel that for this particular era of Star Trek we can still get a good approximation how stardates worked (or were supposed to work).
Again, here is an excerpt what I wrote on page 6 of this thread:
The original episodes were broadcasted out of production order (and out of the modest chronological stardate order these had). Asked about the discrepancies Roddenberry referred to the manipulation of space and time (by the warp engines) and concluded
“I’d just as soon forget the whole thing before I’m asked any further questions about it.” (The Making of Star Trek)
The creator didn’t know yet and the correct answer would have probably been “I’ll tell you when I’m finished telling my 5-year-story" (because only then can I calculate the elapsed time between the first and last stardate mentioned and give you an approximation).
But at the time of the Whitfield interview Gene Roddenberry couldn’t foresee, yet, when he was actually and terminally done telling his 5-year-story.
In this
recent thread I presented the theory that Christmas always happened around Stardate X700.X
This would suggest that 1,000 stardate digits equal one year, but whether that was intentional or accidental is unknown.
Anyway, assuming that Roddenberry sat down during pre-production of TMP and considered giving us a better approximation of stardate values, he inevitably would have noticed that the difference between the earliest (1277.1 or 1312.4) and latest (5930.3) TOS stardate is rather close to 5,000 units (= 5 solar years).
The novelization states the launch stardate from drydock as Stardate 7412.3 and (novel only!) 2.7 hours later it's Stardate 7412.6 while the Enterprise is still cruising at sublight and doesn't warp/alter the fabric of space and time.
This perfectly matches the assumption that 1,000 stardate digits equal one solar year, 2.736 digits one day and 0.114 digits one hour, but - of course - only reflects in the novel and not the actual film's dialogue and figures.
The one thing that doesn't work is the TMP stardate in relation to the last known TOS stardate.
Assuming the last TOS stardate is around Stardate 6000.0 the difference to 7412.3 comes very close to 1,500 units or "eighteen months redesigning and refitting the
Enterprise" but - unfortunately - fails to acknowledge that the actual time difference between TOS and TMP is closer to three years.
TMP summary: While Gene Roddenberry's novelization hints a stardate system where 1,000 digits equal one year, it doesn't reflect in the final film.
Next we have TWOK which takes place 15 years after events in "Space Seed" at Stardate 8130.4.
Before we jump to the premature conclusion that the system doesn't work, we should first answer the question what actually happened in the TOS era when a stardate reached 9999.9. Would the system have restarted with Stardate 10000.0 or simply [1]0000.0 ?!?
In the latter case the difference between "Space Seed" (Stardate 3143.3) and TWOK (Stardate [1]8130.4) is 14,987.1 digits which would be so close to 15 solar years (15,000) that it's actually too perfect to be written off as a mere coincidence
TWOK summary: Assuming events took actually place on Stardate 18130.4 emphasizes the 15 year difference mentioned both by Khan and Kirk and supports the theory that 1,000 digits should usually equal one year.
The next two films follow shortly after events in TWOK. At the beginning of TVH (ST IV) Kirk records Stardate 8390 "in the third month" of Vulcan exile. He stole the Enterprise
after Stardate 8210.3, so the difference is 179.7 digits or 65.68 days. 61 or 62 days would equal two months, so indeed at the beginning of TVH the third (solar) month was just several days old.
TVH summary: Further evidence that 1,000 digits should usually equal one year.
Sulu's remark in TUC (ST VI) that he has been Captain of the Excelsior for at least three years at Stardate 9521.6 makes it clear that this is no longer the stardate cycle during which events of TWOK, TSFS and TVH took place but a new one and therefore and accordingly it would be Stardate [2]9521.6.
The time difference between TWOK (1982) and TUC (1991) would be approximately 11 years in the Star Trek universe, which doesn't seem too unrealistic considering that the time difference between both films in real life is 9 years and 6 months (and because humans in the 23rd Century have a longer lifespan it stands to reason that they may have aged 11 years but still look as if they had only aged 9).
