From: tallman@ailanthus.com (Robert Oliver) Subject: STARDATE UPDATE (and correction) Message-ID: Date: Wed, 06 Jan 93 02:00:43 EDT Organization: Ailanthus Project Lines: 572 UNITED FEDERATION OF PLANETS REVISED STARDATE SYSTEM * SOL SYSTEM SD RD EVENT 9521 2294? Star Trek VI: The Undiscovered Country (This is an old system stardate) The stardate system apparantly changed sometime in this timeframe. I assume they would start at SD 10000 to avoid conflicts with the previous system, but this leaves about a 39 year gap between the two systems. It is possible that the Federation changed to a completely different timekeeping system during this period that had nothing to do with the old one or the TNG one. Who knows? STANDARD YEAR 1000 Stardate units in each year of 365 days Each day has a range of 2.739726027397 SD units LEAP YEAR (not calculated here) 1000 Stardate units in each year of 366 days Each day has a

The first part of the equation is to confirm the fact that each year contains 1000 stardate units. This is pretty easy if you look at the 6 seasons and the way their stardates are ordered: Season 1: 41153 - 41986 Season 2: 42073 - 42976 Season 3: 43125 - 43989 Season 4: 44001 - 44995 Season 5: 45020 - 45965 Season 6: 46001 - ????? 2. The second part is to find another stardate/real date correlation to support this. I found this date in the Khitomer Massacre. Using Worf's birth date of 2340 (taken from a poster that uses info from the series and the "Conundrum" episode, and which matches every canon reference made in the series) and the fact that he was 6 years old when the event occured (Season 3, "The Bonding") we know that the Khitomer Massacre happened in 2346. Working backward from Season 1, the stardate range for this time period should be in the 23000's. According to the ST:TNG Companion there is an Okudagram in the episode "Sins of the Father" that says that the USS Intrepid (on which Sergey Rozenko was serving on) arrived at Khitomer on Stardate 23859.7. 3. Using this as proof that there are 1000 stardate units in each year I went ahead and calculated what the stardate would be for each calendar day. Because of the effects of "relativistic time dilation" this system is only accurate for the stardate in the Sol System, specifically Earth. How the stardate on Earth relates to various other parts of the galaxy is a complete mystery to me. The most glaring stardate discrepancy in TNG is the death of Tasha Yar. Below is a list of the episode in which she dies and the three episodes she appears in that have stardates higher than that. Skin of Evil SD 41601.3 Yar dies The Battle SD 41723.9 Yar appears The Arsenal of Freedom SD 41798.2 Yar appears The Big Goodbye SD 41997.7 Yar appears The episodes were aired in a different order than their production order which is the real world explanation for the differences. Since season 2 the episodes have almost all been in stardate order with only a few exceptions. One of the reasons that the TOS stardates were so screwed up (besides the fact that they didn't give much thought to it in the first place) was that episodes were rarely aired in order of production due to the lengthy time it took to do optical effects in the late 60's. An episode filmed before others might be delayed for weeks if there were numerous SFX in the episode. TNG, while having more numerous and complicated effects, makes use of modern digital compositing and editing equipment and 2 alternating SFX teams to handle its load. Another stardate out of order is in ST2, when the engineering log display shows that Spock died around SD 8128.78 when the first stardate mentioned in the movie is 8130.3. All these references indicate that the stardate is variable due to one's relative position (to Earth?) in the galaxy. 4. October 4, 2363 * SD 40759.5: Stardate at Utopia Planitia Yards, Mars for the USS Enterprise D commissioning ceremonies from the TNG Tech Manual. A math mistake on my early work on this system showed that these ceremonies would have taken place at noon on the 4th. However, after correcting my math, it turns out that this event took place on the 5th of October. Great, I thought to myself, it doesn't work! It was then that I remembered the reason I had screwed up the math in the first place--the Leap Year. My original short post on the net used a 365 day year but actually had an extra day that it shouldn't have had--February 29 (only appears in a leap year). Assuming that 2363 is a leap year then the stardate *is* correctly placed on the 4th (near midnight). Multiplying 2.732240437158 (1000 divided by 366) by 278 (adding one day to the normal count for Oct 4) the result is 759.5628415299 I make no claim for devising this system as it is apparant that Mike Okuda worked this all out years ago (including leap years). His upcoming Star Trek Chronology (written with his wife Denise and currently scheduled for March 1993) will hopefully provide more information about stardates. 5. This system applies only to TNG. The TOS system is a confused mess that does not follow any sort of logic. We can assume that the movies use the same system as TOS but there isn't enough information to make any conclusion. The following conversions make no provision for leap years. I have not taken the time to work out which years are standard and which ones are leap years.
