After a bit of detective work and calaculating I believe I have come up 
with the best (but by no means definitive) answer for an age old and 
constant question that pops up on the net all the time--what do stardates 
in ST:TNG mean, and what relation do they have to our 20th century 
calendar? 
   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 - ?????
 
   The second part (which was part of a post I made a few weeks ago) 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 Rozhenko was serving on) arrived at Khitomer on Stardate 
23859.7.
   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. The information below is only a partial list as I have yet to 
complete the whole thing and was curious to get to the month of October 
(more on that later). If anyone is interested in seeing the completed 
final list then let me know.
   Because of the effects of "relativistic time dilation" (witness the 
death of Tasha Yar, she shows up in 3 episodes with stardates higher than 
the one in which she died) 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. This 
system only applies to TNG.

According to the ST:TNG Technical Manual this is the stardate at the 
Utopia Planitia Yards on Mars for the USS Enterprise D commissioning 
ceremonies. As you can see from the info above this date does fall on 
October 4 using a 1000 stardate units = 1 Terran solar year system. 
Taking into account a slight difference in the Mars "time zone" it would 
appear the ceremonies occurred at noon. This makes it clear that there 
are at least a couple people (Okuda and/or Sternbach) who are trying to 
keep up the continuity of ST:TNG. This gives me high hopes that Okuda's 
Star Trek Chronology book should be excellent (even if it invalidates my 
own timeline). Of course, the ST:TNG Manual isn't really canon, so I 
suppose this is all just one big coincidence.
   Well, hopefully this will shed a little light on a subject that is 
brought up far too often. Of course it is quite possible that I made some 
stupid math errors and that all of the above calculations are a bunch of 
nonsense :). Again, let me know if you are interested in the final list. 
I would post it sometime in the middle of January to allow all of the 
college students to get back.
