Talk: Galactic Standard Calendar

Journal of Master Gnost-Dural

I know it's been a perennial issue of fanon that the Old Republic dated events from its founding, but there has been little to no actual canonical proof of that.

There is now.

The The Journal of Master Gnost-Dural, the real-world book released as a promotion for Star Wars: The Old Republic, uses for its calendar entries that track years since the founding of the Republic. That's a C-canon book, written from an in-universe perspective, giving dates with the years in the 21000's for the era of Star Wars: The Old Republic. While we know that dating to the Treaty of Coruscant would be popular afterwards, we now also have canonical proof that the founding of the Republic was also used as an epoch for dating.

Now, officially we don't know what this is dated as, if it's "Republic Year" or "After the Founding of the Republic" or what term for it, but we know the Old Republic circa 3600 BBY used it to count the years.

12 month calendar

Lucasfilm and the authors utilize a 12 month calendar. Why is there no mention of that on this page?? The 10 month calendar was extant at the time West End Games was around, but is no longer in common use. I'm not saying it should be removed, but there should be a section on the days, weeks and months of the current 12 month calendar.72.68.228.25 01:59, 17 August 2008 (UTC)

• I, for one, agree that the dating system on this Wiki need major revisions. This page shows a ten month calendar (eleven if you include the fete weeks and holidays), but pages such as 21 BBY use a twelve month calendar (e.g., the Battle of Virujansi being 14:12 rather than 15:1 or 15:2). Unfortunately, such a large revision requires either making the years longer or the months shorter, a task easier said than done; nevertheless, to improve accuracy and consistency, I think a revamping of the calendar is in order. Axinal 19:34, January 4, 2010 (UTC)?
• Semi-official practice has been to change old dates to new dates without any editing. In the past nothing interestning has happened in months 11 and 12. I have no idea what they are going to do dates including days 32-35 in these months though. The solution is too easy for my taste, but it is hard to resist the forces behind these decisions.--Telccu 06:53, February 25, 2011 (UTC)
• I must agree with the statement above. The talk page is most likely dead, but that isn't the point. The names for "Days of the Week" have no sources, in addition to the Standard "Calculator" for time. I agree with Axinal about the Battle of Virujansi, since it has sources about Month 11. Perhaps it could be the Fete Week, it probably isn't; no sources are listed for Month 12. I strongly recommend the clean-up, but after seeing that after 10 months have gone by after the post above, it probably may not happen as I expect. :(

It's worth noting that 368 days is 30 remainder 8. The calendar dates given in wiki article and in the Atlas both have 5, 7, and 10th months with 31 for certain; this could easily be every month divisible by 3 has 30 days, with a default of 31. (Pattern 31/31/30/31/31/30/31/31/30/31/31/30). It's also worth noting that Canon has multiple calendars in use, as the Lothal Calendar is part of new canon (being used in Rebels).

KOTOR

Does anyone know what dating system was used in the KOTOR era? Certainly not BBY, GR or even RR... (Or maybe there is no canonical one, so it's safe to introduce an arbitrary system in a fanfic? :)) - Sikon [Talk] 17:03, 20 Oct 2005 (UTC)

I know this is Fanon but, what about PFR or Post Formation of the Republic, therefore KotOR would take place 25,000 PFR.Adventfear 12:51, 31 Dec 2005 (UTC)

• I agree with Adventfear. Since we know (or believe) the Galactic Republic was formed in 25,000 BBY (or around there), hence, the Sith War would be from 21,000-21,004 PFR.
• Could we edit that in here somehow? Doran 22:40, 27 March 2006 (UTC)
• No you can't. It is fannon (to my knowledge). There was no dating system given for KOTOR. There is a system for the upcoming The Old Republic video game...this is mentioned in the article. —Unsigned comment by IthinkIwannaLeia (talk • contribs)

GR to GSC

Can we assume that when the New Republic converted from the Great ReSychronization calendar system to the new Galactic Standard Calendar, the did not decide to begin the first month of the first year on the day of the battle? I would assume that they merely changed 35 GR to 0 BBY, so that the day of Alderaan's destruction went from 35:3:7 GR to 0:3:7 BBY. Otherwise, all specific dates offered by Galaxywide NewsNets or Holonet News are useless. Thoughts?--SparqMan 20:13, 6 Jan 2006 (UTC)

• I think that's a good assumption, since it seems all the New Year's fete weeks didn't change dates (nor end up in the middle of the year). QuentinGeorge 07:45, 12 Jan 2006 (UTC)
• I dunno; it certainly seems in the sources that use the BBY/ABY dating that the Battle of Yavin is the zero point. That doesn't make the dates in the news useless, it just means that there's an extra layer of math to get their dates in relation to Yavin. jSarek 11:20, 12 Jan 2006 (UTC)
• Just a question, is the GSC format the same as GR (Year:Month:Day)? —Unsigned comment by Nick sponge (talk • contribs)

BTS idea

I've noticed with aloto f Fanon userpages on Wookieepedia (i brows them for writeing ideas) that people tend to use a certain idea for dateing ujseing there own birthdays in relation to 1977/0 BBY Valin "Tnu" "Shido" Suul 03:12, 16 November 2006 (UTC)

Not sure that's significant enough to add, but it did inspire me to make this slightly sloppy table of Star Wars versus real world dates, using a slightly different system. According to it I was born in 4 ABY, but since 4 ABY lasted 3-8 years that doesn't say much. --Andrew Nagy 04:33, 8 July 2009 (UTC)

Yavin vs Endor

Is there any in-universe explanation for the Battle of Yavin rather than the far more important Battle of Endor is used for year zero in the GSC? On its face, that makes absolutely no logical sense. Red XIV 09:23, 4 February 2007 (UTC)

I thought that was odd as well. Sure yavin was a great victory, but they did not actually win freedom until Endor. --Smuggler Freak 23:43, 23 February 2007 (UTC)

The Battle of Yavin was 1000 years after the Ruusan Reformation, where as the Battle of Endor was 1004 years later. Using the Battle of Yavin both indicates when the tide first turned against the Empire, and kept the last digits of the year the same. So old year 1000, becomes new year 0. This works much better than having old year 1004 become year 0. Under the ABY system, old year 1027 would become 27 ABY. This would have appealed both to people who wanted to return to the Ruusan Calendar, and those who wanted a new one. —MJBurrage • TALK • 10:27, 11 June 2007 (UTC)

I agree determining all events according to the Battle of Yavin is a bit arbitrary. After all, was it really so important an event that the Empire, which didn't even last three decades, lost a major space station? But we're sort of stuck with it because the vast majority of novels, comic books and what not that bother to place its events in a historical context do specify the events in the number of years before or after the Battle of Yavin. Fortunately, however, something important did happen the same year that makes it significant, even though it was a throw-away comment in the original movie. It is the year the Republic, the Old Republic, was dissolved officially. As Tarkin coldly states, "the last rudiments of the Old Republic have been swept away." Sure, the Republic really fell 19 years before when Palpatine declared himself emperor, but the Republic officially persists until Palpatine dissolves the imperial senate the same year as the Battle of Yavin. That makes the year significant. Besides, when is the new republic officially established? Is it year 4 ABY when the Empire falls? Or does more time pass? It's simply easier and more convenient to measure time compared to the official fall of the Republic, when the emperor dissolved the senate. Jediphile 19:07, 24 July 2009 (UTC)

Becuase that was the Rebels first great victoy against the Empire. This is why and plus George Lucas said it is year zero, and we all know that we must listen to what he says.T-888

If we were really going to reset the calendar, then Naboo should be year zero. That's when Palpatine's plot really went into full effect. 199.79.253.5 20:01, September 29, 2016 (UTC)

Inconsistency

The Galactic Empire used the same calendar, although they preferred to date events from the Great Resynchronization of 35 BBY, or from the Declaration of a New Order (19 BBY).

It is unknown what calendar was used by the Galactic Empire.

Why does this article contradict itself?... Klow 22:40, 2 April 2007 (UTC)

• Does anyone have an answer, please? Klow 00:48, 14 May 2007 (UTC)
  • Well, feel free to fix it if there's a contradiction. —Unsigned comment by Crazy Jedi Girl (talk • contribs)
    • Ok, I'll have a look. Klow 11:07, 10 June 2007 (UTC)
• It's not a contradiction, per se. It's possible to know how they measure the year without knowing how they structure the months and days. Most people have a clue that the Roman Calendar dated in years, for example, but most are unaware that it varied from 300 days to 378 days, depending upon when in the history of Rome one is. We know that they counted by "Year of the Reign of Emperor ___" for most of Imperial Roman history... So, we know they count years like everyone else... but not how they subdivided them officially. No contradiction Akaramis (talk) 06:24, March 22, 2017 (UTC)

Questions...?

This article is very helpful, but there's one thing... Are the month and day names used by the Tapani Sector used everywhere in the galaxy, or do other sectors and systems have their own names? What names do the Jedi use? I mean, I doubt that everyone goes around saying "the third day of the seventh month", or "the fifth day of the week". Is there any information on this anywhere? Isn't there any book or comic or anything where someone not from the Tapani sector mentions a date?

Just wanted to know... --Crazy Jedi Girl 20:38, 23 April 2007 (UTC)

Local Calendars

Out of curiosity, would certain planets that preferred their local calendar system be allowed to use it rather than Galactic Standard, even if just for local purposes? --DanMat6288 16:27, 2 December 2008 (UTC)

Of course they must have had local calendars. Just because their length of day and year would have differed from Coruscant norm. It would be hard to follow 368 day year on Earth. It would be more difficult to use for example 30hour day. Also rarely ppl come to think that all planets have time zones too, not just one local time. Telccu 18:51, 25 August 2009 (UTC)

0 BBY/ABY

A simple question: was there a 0 BBY/ABy year? Mauser 18:46, 15 February 2009 (UTC)

• A simple answer: Yes. According to the by-year chronology (which uses a twelve-month year), Year 35 after the Great ReSynchronization is referred to as 0 BBY up to the Battle of Yavin (in month three) and 0 ABY for the rest of the year.--Larry660 11:15, 17 February 2009 (UTC)

what was it called..

What was the calandar based on during the BBY era??? It's not like they would create a time on a fake (at that point) period! Even if the jedi sensed it, it has not happened yet! Their visions have been wrong before (at least blurry)!!! I have made my point.  :) Sorcerer123 00:47, 5 May 2009 (UTC)

369 vs 368 days in year???

It says 369 days per year. I thought it based on Coruscant year and it is 368 days. If you agree with me and you´re sure of it, change it, please. Telccu 18:57, 25 August 2009 (UTC)

11th month recordings

From Article: "Although using the Tapani Calendar has proven effective, some events were recorded as occurring in month 11, as the Galactic Standard Calendar placed the festival weeks and holidays together as a form of short month."

• I have seen stuff happen in month 11 at least during Clone Wars (Article 22 BBY). So, are these events happening between other months? Isn´t that kinda confusing if you don´t know exact date? Then the event may have occured early in the year or end of the year and there´s no way of knowing.Telccu 19:04, 25 August 2009 (UTC)

BBY & ABY VS. Other dating systems

I think that the BBY and Aby dating system is much more simple and easy to use than the other ones out there can we for the sake of the site just use the BBY and ABY? T-888

What Happened!

This page originally had the names of the months. RIGHT! I think that I hate this page know! —Unsigned comment by Jedikenobi33 (talk • contribs)

• Those months weren't part of the Galactic Standard Calendar. They're part of the Tapani calendar, and belong in that article, not in this one. jSarek 13:11, December 14, 2009 (UTC)

Days in a week

What is the source of the Time measurement section? This article says there are 35 days in a month. The Holonet News says different. It is a weekly newspaper. Issue 45 released in 13:2:28. Issue 46 relesed in 13:3:7. So the second month consists 28 days, like our February. The other issues give us the other month: 3rd month consists 31 days and 4th month consists 30 days. Darth Morrt 15:54, December 21, 2009 (UTC)

• There are 2 different calendars in use. 10-month calendar was used earlier, but during clone wars production Lucas and co began to use 12-month calendar to simplify things. Your examples seem to indicate that Holonet News used the same. --Telccu 06:46, February 25, 2011 (UTC)

How many days in a year?

I'm sorry to say this, but 10*35+3+3 aren't 368! What of both is correct then? - Alta Ranga 07:24, July 25, 2010 (UTC)

• 10*35+3*5+3 is 368. There are 3 feet week. But this calendar is a outdated in some way. The authors use 12-month, Earth-like calendar. Darth Morrt 07:41, July 25, 2010 (UTC)

Revamp of Clone Wars event dates in The New Essential Chronology required?

On this site, the following years of the Clone Wars (in the BBY/ABY system) have been given their GrS equivalents on their respective pages, i.e.

22 BBY = 13:3-14:2 GrS; 21 BBY = 14:3-15:2 GrS; 20 BBY = 15:3-16:2 GrS; 19 BBY = 16:3-17:2 GrS

It is stated that the Clone Wars began in 13:5 with the Battle of Geonosis, and this date has generally been given as 22 BBY. Apparently, the BBY dates given in the NEC for the Clone Wars events assume that Geonosis occurs EXACTLY at the beginning of the year 22 BBY (which, as can be seen from above: 13:3 vs 13:5, is clearly not the case). Thus, in this book, events occurring at 12, 24 and 36 months after Geonosis are also taken to occur at the start of each new year.

As such, using the 12 month calendar, events like the Battle of Boz Pity (31 months ABG, 5 months before ROTS)are given as 19.43 BBY (if you add 5/12 to 19 BBY you get 19.41666667, which approximately corresponds to that "seventh" month in the 12-month calendar for 20 BBY). But by using the GrS, Boz Pity occurs at 15:12, which is like in the TENTH month of 15:3-16:2 aka 20 BBY, so in the BBY system it should be approximately 19 + 2/12 = 19.17 BBY or so, instead.

Deriving the given BBY dates for other CW events in the book yield similar results. There is a systematic error in the calculated values published in the NEC.

Comments anyone? I think a higher authority really needs to look into this seemingly trivial but in fact cardinal matter.

Especially with the current hype about the Clone Wars, not to mention the new, as yet unrevealed timeline for events in the 3D animated series. The old timeline at least deserves some correction/closure in order to prevent a similar incident happening with the upcoming new CW timeline. —Unsigned comment by 210.24.113.129 (talk • contribs)

Retconned by Leland Chee?

In his 2011 version of the Timeline Gold, Nathan Butler says: "In 2009, Leland Chee (at my suggestion) officially deemed all pre-2002 '10-month calendar dates' to actually be from a 12-month calendar system in which we just never happened to see dates in Months 11 or 12 by sheer coincidence. This has allowed me, as of June 2010, to convert all of those already-converted dates back into a much simpler format that simply follows a 12-month calendar throughout the entire document."

I would like to know if this is true: did Chee really deem the 10-month system non-canon? If it is true, the article should be rewritten to erase the ten-month calendar from memory (except in BtS of course), as it is know obsolete canon. I'd ask Chee myself, but he hasn't seemed too keen on answering questions for a few months... --LelalMekha 10:25, June 16, 2012 (UTC)

Legends VS Canon

Since this is now relegated to Legend canon until otherwise stated should we keep using it on canon articles (for example Heir to the Jedi) or switch to something like "X Years Before/After A New Hope"? 101.160.177.106 00:35, May 26, 2014 (UTC)

• I was wanting to ask the same thing. Since we have been using this for a while and the new canon has taken effect, until there is a new dating system put in place should we still use BBY/ABY on canon articles? Matt Seay (talk) 13:46, August 3, 2014 (UTC)

    • Nope. They generally talk about the show in relation to Episode IV. And even if they say that it takes place "five years before the Battle of Yavin," that's not the same thing as the establishment of an in-universe calendar system. - Brandon Rhea^(talk) 20:26, November 5, 2014 (UTC)

Canon Dating system

To reiterate this subject again, this article uses BBY while talking about TCW backstory on SW.com. Does this count as a Canon source/official introduction of this calendar to the NuCanon, or does it not count since the author then says that the event in 1000 BBY used to be in Legends? Bane7670 (talk) 19:37, March 27, 2015 (UTC)

• Not a canon source, no. SW.com blogs are not sources for new information unless they explicitly state otherwise (like a recent one about the Max Rebo Band). They're simply a recitation of existing, licensed information. - Brandon Rhea^(talk) 19:45, March 27, 2015 (UTC)

Why this can't and shouldn't ever be considered canon

http://starwars.wikia.com/d/p/2871350595258680721 --ChristopherLeeGallant (talk) 22:32, November 5, 2016 (UTC)

• You know, this here article is Legends, and we haven't made a canon version because the name "Galactic Standard Calendar" hasn't appeared anywhere in canon. Besides, Pablo Hidalgo did not say BBY/ABY isn't canon, he said it's not necessarily standard/universal. There mere fact that the system is used in a canon source (namely the Galactic Atlas) makes it canon. And even though it may not be standard as it used to be, it's the most convenient system for us to use. --LelalMekha (talk) 23:02, November 5, 2016 (UTC)
  • I agree and disagree. Since a in-universe canon character is using the date system, it should be canon. But it's not a calendar standard. So yes, a new wiki canon entree needs to be made here, but it can't be called Galactic Standard Calendar as it's not a 'standard'. It's simply a canon measurement tool within canon. --ChristopherLeeGallant (talk) 00:58, November 6, 2016 (UTC)
    • But, to my knowledge, nobody ever considered creating an article called called "Galactic Standard Calendar/Canon." ;-) This will probably be something like "BBY/ABY system" with a conjecture tag. --LelalMekha (talk) 09:24, November 6, 2016 (UTC)

Conversion to Gregorian

It is possible for any of the Star Wars calendars to be converted into the Gregorian Calendar? For example, what would 2021 AD be considered what year according to the Galactic Standard Calendar or Battle of Yavin Calendar? (DarRam (talk) 13:32, 23 August 2021 (UTC))
