Calendar Wiki

You have created a category "Sovereign calendars." I am not familiar with the term. What is it supposed to include? -- BruceG (talk) 23:28, September 28, 2012 (UTC)

I wanted to create a category for all calendar proposals that are not minor improvements to the Gregorian calendar and couldn’t think of an appropriate term to parallel Category:Reformed Gregorian calendars. If you have a better suggestion, I’m more than willing to rename the category. I haven’t tagged all applicable pages yet, anyhow. Crissov (talk) 08:52, October 1, 2012 (UTC)
How about something like "Radical proposals"? -- BruceG (talk) 12:05, October 1, 2012 (UTC)
Since some of them are not proposals, but have actually been used, I changed it to Category:Unusual calendars, although that name is also not perfect. Crissov (talk) 16:39, October 15, 2012 (UTC)
It could have been "Radical designs" or something. — Hellerick 20px 15:09, October 17, 2012 (UTC)
Yeah, could have. You are welcome to change the articles. (Sadly changing, removing or renaming categories is not as quick and easy as adding them.) Crissov (talk) 11:01, October 18, 2012 (UTC)
Since that term seems to be acceptable to everyone, I've gone ahead and made the changes. However, I don't think your description would include the Swedish calendar so i've deleted that category from that article. -- BruceG (talk) 13:59, October 18, 2012 (UTC)

In the page titled "international Calender" is a table called "Possible Leap Cycles"  It mentions years of 293, 400 and 817 years.  One possible addition that appears to meet the criteria is a cycle of 231 years.  It's a 33-year leap-day cycle times 7. This cycle has 84,371 days, 12,053 weeks, 56 leap days, and 41 leap weeks. There are 365.2424 mean days in a year, and 52.1775 mean weeks, There are 2857.0713 lunations. 23:30, July 31, 2014 (UTC)Walter Ziobro

Note to the person who suggested this: You are permitted to add things like this yourself. You don't need anyone else to do it for you. -- BruceG (talk) 00:44, August 1, 2014 (UTC)
I’ve updated Template:Leap cycles accordingly (it’s transcluded at International Calendar), but BruceG is right of course. Crissov (talk) 12:15, August 1, 2014 (UTC)

Decimal 3-Year Calendar[]

I notice that on your page "Decimal 3-Year Calendar" you have a problem with the infobox. Since I haven't figured out your infobox template, I can't fix it, but I'm notifying you so you can. --BruceG (talk) 11:47, March 23, 2016 (UTC)

I know, the infobox isn’t perfect yet (at all). This is one of the first pages using it and it is helping me to figure out which parameters should be there and what should be their possible and default values. Crissov (talk) 14:02, March 23, 2016 (UTC)


I'm not sure if you're really the person who'd know this, but I figured it was worth a shot.

I'm an admin on the wiki for a fantasy book series that uses it's own calendar system the author invented. The system has a 361 day year, and dates are counted in seasons, not months—for example, Winter 82 is a date. Spring and fall have 60 days, summer and winter have 120, and there's one intercalendary day that's not part of any season. It could be counted as a fifth, one-day season, I guess.

Because that's the system used to refer to dates within the books, it's also the system we use on the wiki to refer to the dates of those same book events. I'd like to get some code templates us to support that system. Do you know of any that I could alter to fit this system?? -R.A.B. 03:37, March 30, 2017 (UTC)

I'd gladly help, but I'm not sure I quite understand what exactly you are looking for. Crissov (talk) 23:03, March 31, 2017 (UTC)
I'm looking for calendar templates than can easily be altered to fit a calendar other than the Gregorian one. -R.A.B. 06:21, April 3, 2017 (UTC)
I don't think we have anything on here that is flexible enough for the case you described. Crissov (talk) 09:31, May 9, 2017 (UTC)



i'm currently looking for a lunar calendar with a particular pattern. As you seem to be quite active in this wiki i'm guessing you may be able to help. :)

The calendar i'm looking for has 12 month (presumably determined by the moon) and has intermitting length (30, 31, 30, 31,... or something like this). Only that two month of the year break this pattern being 30, 30, 31, 31 or something similar. Do you have a guess on which calendar this might be?



Check out Category:30:31 mirrored and Category:31:30 mirrored: of the calendars categorized in this wiki, only the Standard Calendar matches your description. Walter Ziobro also designed a calendar that has month lengths repeating in a 4-year cycle (olympiad). Crissov (talk) 15:11, April 25, 2019 (UTC)

Lukashian Calendar[]

Hello Crissov, I'd like to notify you of a new proposed Calendar that has recently been released: The Lukashian Calendar. The website,, includes an actual working version of it, along with a description of how it works. I thought it would be interesting for your list of alternative calendars.

Kind regards, GJ Schouten

Hi, I have since added the page to the Calendar Wikia, thanks a lot for this platform!
Hi! Sorry for not replying earlier. I think this is the best way anyway. I’ll have a look whether I can improve the article somehow. Crissov (talk) 14:39, September 26, 2020 (UTC)

About the Cesidio Tallini and Kaisiris Tallini articles[]

While we can agree to disagree on whether certain articles belong, or not, in the Calendar Wiki: these articles are about the author of the Cesidian calendar, who is not a con artist, as you so describe him, although you may naturally disagree with his religious, scientific, and even legal views, since his religious, scientific, and legal views are based on 22, almost 23 years of research and development not funded by any UN government, or UN government accredited institution, and thus above any government or monetary institution's self-serving interests:

I would appreciate it, if you eliminated thus the ad hominem attack on Kaisiris Tallini (aka Cesidio Tallini) at least, or I will assume that the Calendar Wiki also violates Cesidian law (it wouldn't be the first wiki to do that), and that comes with non-recognition of any articles, including the Cesidian calendar articles, as being authoritatively written, and thus morally respectful of the author of the Cesidian calendar.

This wiki is about calendars: those actually (or previously) in use, proposed ones and also fictitious ones. It is not intended for documenting full fictitious worlds, a.k.a. constructed worlds or conworlds.
Also, it’s considered impolite to refer to oneself in the third person. Crissov (talk) 18:27, 25 May 2021 (UTC)
As I said, I'll agree to disagree, because while the Cesidian calendar is used daily, since only a minority uses it, it could also be considered part of a constructed world. However, ad hominem attacks, such as wanting to also eliminate any reference to the creator of the Cesidian calendar is particularly impolite, if not outright offensive. If you don't like the person at all, or so much so that you'd leave him, and all his creations obscure to the world, then you are an obscurantist and dogmatist. You have to understand that the Wikipedia itself had either no references, or almost no references, to a Nobel Prize winner prior to her winning the Nobel Prize, and you seem just as addicted at keeping people obscure, until the GOD-like media discovers them! You are even worse than the pope in the time of Galileo, another obscurantist and dogmatist. I hope you are a little bit above that. Kaisiris/Cesidio Tallini, 02:11 26 May 2021 (UTC)
You are funny, but seriously: nobody obstructs information about your calendar designs here, and you can put on your user page whatever you deem important, but those dedicated articles that I quoted on your Talk page are simply out of scope for this wiki. Crissov (talk) 13:24, 6 June 2021 (UTC)
