Stardate calculators

Personal log, stardate 60262.6.

I found the following stardate calculators on the Web. There are also a couple of smart phone apps. There is clearly no consensus between them.

Does anyone use these or other methods in their personal logs?

Star Trek Stardate Calculator

IIRC, that one is used for figuring out stardates in the novels and the current shows, though it's inconsistent with the times in the Berman era when a stardate and actual date were given, like Voyager Homestead.

If, by “current” you mean Picard, it works very well. Stardate 78183.10 is March 8, 2401, Time: 19:57:21, and that’s the date it aired on P+. Stardates from 1987–2002 also work reasonably well.

Putting in today, I currently get -299130.19006849325, which I’ve seen elsewhere, but it’s ugly.

I didn’t know about the novels.

If I combine the year 2401 with today’s date and current time, I get 78869.8630136987, or 78869.86, to be less precise. That’s more like a real stardate. That would be counting from 1945 instead of 2323.

I’m working on my own calculator, and it’s close to what I came up with: 78870.80.

In the Kelvin universe, the stardate is 2023.318

In the Kelvin universe, the stardate is 2023.318

So in the Mirror Universe it would be 813.3202?

I found the following stardate calculators on the Web. There are also a couple of smart phone apps. They all convert dates in the 21st century. There is clearly no consensus between them.

Stardates are gibberish. They were never meant to be taken seriously. Which is why you'll never find a good converter for them.

This is true, look no further than Discovery bringing back TOS' totally random numbers. I have no idea if Strange New Worlds has any kind of system but I kinda doubt it.

I’m not looking for a “good converter.” I’m just looking at emulators. They don’t have to match any episodes, just give some number I can post in my logs, now, in the 21st century. I was wondering if there was one that was preferred. I remember people doing that back during TNG days.

Seldon’s log, stardate 63345.3

Probably your best bet would be to make one yourself.

Done.

  function tng(DateStr, epoch) {
   var year = new Date(DateStr).getUTCFullYear();
   var yearlength = (!(year%4) && year%100 || !(year%400)) ? 366 : 365
   var doy = (DateStr - Date.UTC(year,0))/ms; // elapsed days of year
   return (1000*(doy/yearlength + year - epoch)).toFixed(1);
  }

epoch is year of origin, like 2323, 1945, etc., assume Jan. 1
DateStr is string contain calendar date e.g. "Tue, 21 Nov 2023 12:28:41 GMT"
stardate is difference between epoch and date e.g. 2023 - 1945, times 1000

 

[XCV330]

So in the Mirror Universe it would be 813.3202?

they probably just go with dating back from whatever year the current emperor took power, or maybe the founding of said empire. If they are just using Julian Date then today is
XXMMMCCCXVIII
or 23318.

 

[1001001]

Or

(Now.getTime() - new Date(1987,0,1).getTime())/31557600 + 41000;

A+ for enthusiasm, but please don’t post so many times in a row. 2 at most.

Thanks

As well as Lower Decks, Prodigy and Disco, at least after they moved to the 32nd century.

Stardate 78183.10 is March 8, 2401, Time: 19:57:21, and that’s the date it aired on P+.

?
No episode aired on March 8. That particular stardate is from S3E4 No Win Scenario which actually aired on March 9. And if that's the date they gave, then that's actually rather problematic given the entire third season is supposed to take place over the span of the week leading up to Frontier Day, which is supposedly in mid-April.

Stardates from 1987–2002 also work reasonably well.

Except for the one I stated, Voyager Homestead, which has the stardate 54868.6, which that calculator site gives as November 14, 2377 while the date stated in the episode is April 5, 2378.

I already did, have had one made for quite a bit.

Spoiler: My version of a Updated StarDate/Time system

 

[C.E. Evans]

When I was writing fanfics, I used the "TNG formula" for determining stardates from 2324 and onwards, with the idea that it began with stardate 1000.1 in 2324. When coming up with a stardate for our time, I fell back on the old FASA reference system which I believe begins with the year 2000 or 2001. If I'm not mistaken, the idea was based on a theory that each starship had her own mission stardate clock, but the reference system was more of an actual calendar for Earth and other Federation worlds?

As such then:
November 15, 2023 would probably be stardate 0/2311.15
April 23, 2188 would be stardate 1/8804.23
September 8, 2266 would be stardate 2/6609.08
And so on...

Any log entry made after the initial one for the day would simply be "supplemental."

 

[Nike]

My brain hurts. I wouldn’t know how to begin implementing that.

I like that you divide the time of day into decimal. None of those online calculators do that, but it’s part of the original specification.

it seems that you have stardates changing in the future. But we already know how they look in the 32nd century.

Actually, that’s not quite true. During the TNG-DS9-VGR period, including the TNG films, star dates were pretty consistent, just like registry numbers were pretty consistent. Why? Because there were people working on those shows and movies who actually cared about those kinds of things and wanted to get them right, even if most of the viewing audience could have cared less.

 

[Shamrock Holmes]

They were pretty consistent moving forward, but they were still a mess looking backwards because they didn't think carefully enough about their initial "4 for 24th Century, 1 for 1st season" design.
