Talk:Common year starting on Monday

Color of Sunday dates

 * You're getting worked up over nothing. Not only Western but East Asian calendars use red Sundays. Not making the Sundays red makes the calendar harder to use, as it is easy to make a mistake reading the calendar if you are used to weeks starting on Monday, even with the weekday labels at the top. The convention that "if only one day of the week is colored, then that day is Sunday" is more international than either "start the week on Sunday" or "start the week on Monday", and refusal to use it in an Internet reference work used by people of all nations seems to me too "politically correct". —Preceding unsigned comment added by 75.13.69.183 (talk • contribs)

Clarification: the above question means set up with Monday as the first day of the week. Georgia guy (talk) 21:50, 1 January 2008 (UTC)

I'm here looking for an answer to that myself. Someone should take the time to correct this. –Sarregouset (Talk) 12:53, 25 March 2008 (UTC)


 * "Correct" it? Welcome to the real world. Some people treat Sunday as the first day of the week, some Monday. Some published calendars are one way, some the other. Neither is more correct. In actuality there isn't any "first" day of the week, because every day is preceded by one and followed by another, but since we need a convention for convenience, we choose one. It's becoming more and more common these days to start on Monday because it fits in with the bureaucratic calendar and the weekend. 91.105.41.135 (talk) 23:31, 19 October 2008 (UTC)
 * Show me your source. Georgia guy (talk) 23:53, 19 October 2008 (UTC)
 * I agree, these calendars need to be Sunday thru Saturday with no week number. Let's look at your points:
 * "Welcome to the real world." Uninformative and slightly insulting.
 * "Some people treat Sunday as the first day of the week, some Monday." Which people? Who? How many? How do you know?
 * "Some published calendars are one way, some the other."
 * "It's becoming more and more common these days" How common? More than 50%? Where do you get your numbers? Illiteracy is becoming more common too; shall we rewrite the encyclopedia accordingly?
 * "it fits in with the bureaucratic calendar" What's that? And why would anybody want to "fit in" with a bureaucracy?
 * "and the weekend" How does the weekend "not fit" with the Sunday-first calendar? Do you know some people who are confused by that arrangement?

The relevant International Standard ISO 8601 states that weeks start on a Monday. It's a bit like driving on the right: either convention works but it helps if we all use the same one. Certes (talk) 23:06, 18 December 2008 (UTC)
 * Certes, does "we all" in your sentence mean all living human beings, or everyone of a certain kind?? Georgia guy (talk) 23:35, 18 December 2008 (UTC)
 * I meant "everyone interacting in a single group", such as all WP readers who discuss weeks. A different starting day works in a self-contained context such as a Saudi company working Saturday to Wednesday, just as we get by driving on the left here in the UK. I think the reference to ISO is valid even if the road analogy is not perfect. Certes (talk) 00:50, 21 December 2008 (UTC)
 * Now, look at List of radio stations in Georgia. There is a table that lets you put the station list in any of several different ways. Does anyone know if there's a way to set this up so that users will be allowed to let this start on either Monday or Sunday similar to how the table of radio stations allows users to list the radio stations by callsign or frequency?? Georgia guy (talk) 20:09, 27 December 2008 (UTC)
 * That table uses class="wikitable sortable". I guess that is a wiki software feature, and you would need to raise a bugzilla change request to have something similar implemented for calendars.  Please can someone more familiar with the wiki software confirm or correct this? Certes (talk) 01:25, 28 December 2008 (UTC)

OK, look: This is English Wikipedia. There is indeed an international standard that has changed it to Monday (and "changed" is correct; the Sabbath is traditionally Saturday and not until Protestantism was founded five centuries ago did people start calling the Christian day of public worship a "Sabbath"). But most English-speaking people have never even seen a calendar that begins the week on Monday. I never saw one until I saw one of these Wikipedia pages 20 minutes ago. Michael Hardy (talk) 05:53, 19 February 2009 (UTC)
 * In England, as in the rest of the UK, British Standard BS EN 28601 implements the European Standard EN 28601, which is identically worded to ISO 8601. However, this Wikipedia is "English" in language rather than nationality, so I think a direct reference to the international standard is more relevant. Certes (talk) 15:38, 19 February 2009 (UTC)
 * Actually, it appears that ISO 8601 specifies that "ISO" weeks begin with Monday, but is silent on calendars. A calendar with unnumbered weeks can clearly go either way.  (For what it's worth, the IRS rules on full-week accounting (aka a 52-53 week fiscal year) allow the business to specify the start day of the week and the criteria for determing which weeks including January 1 are in which tax year.)  As for common usage, my employer does have a fiscal calendar in which weeks start with Monday.  However, it has fiscal months consisting of full weeksand the payroll periods are Saturday–Friday, so that's not relevant here.  — Arthur Rubin  (talk) 16:13, 19 February 2009 (UTC)

So how widespread is actual use of the cited ISO standard? (I've never seen it except on these Wikipedia pages.) Michael Hardy (talk) 02:25, 20 February 2009 (UTC)

Sunday has been the first day of the week in the West for 2000 years at least. Every calendar I've ever seen at Borders or Barnes and Noble starts on Sunday. I'm using Wikipedia's calendar for 1849 to correlate some dates to what days of the week they fell on. Sunday was the first day of the week in English speaking countries in the 19th Century. It would be helpful if the calendars here relected that. This ISO standard is not common in the USA outside of some business applications. This calendar should either give the option for choosing a format or reflect the most common and historic usage, not some arcane and obscure descion by some international committee. —Preceding unsigned comment added by Jogden507 (talk • contribs) 23:37, 24 February 2009 (UTC)

I think this whole discussion again shows the narrowmindedness of USA-citizens, and confirms the view Europeans have on them. My native language is not English, however it is the de facto language used on the Internet and the English version of Wikipedia contains much more information than any localized version. Therefore I will most often use the English version of Wikipedia for global lemmas. Calling ISO "some international committee" just to hide the fact you want your personal version of Wikipedia is pretty lame. If Monday is the ISO standard, then let's keep it at ISO standard. After all, USA is only one of the few countries using Sunday as the first day. There are also a few countries having Tuesday as the first day, would you agree to that? —Preceding unsigned comment added by 213.151.218.141 (talk) 19:31, 23 December 2009 (UTC)

Weeks starting on Monday?
Pardon my naivete if this has been discussed at length. Why are the weeks shown beginning on Monday rather than Sunday? Michael Hardy (talk) 05:31, 19 February 2009 (UTC)
 * originally from Talk:Common year starting on Monday: — Christoph Päper 14:22, 20 May 2016 (UTC)

New calendar format
Do we have a consensus for this change from the existing template to a new format and the similar changes to Common year starting on Tuesday etc.? I do not want to revert, because one effect of the change is to start weeks on Sundays which I opposed above, but I would welcome other comments. It is clear from the previous discussions that there is more than one good format for this information and it is not obvious which one is best. Is the right way forward to invite a Third opinion? I do not mean to imply that we have any sort of "dispute", simply that we could use some help in finding the best content for the page, which may well be a blend of the old and new versions. Certes (talk) 00:46, 20 March 2009 (UTC)
 * originally from Talk:Common year starting on Monday: — Christoph Päper 14:22, 20 May 2016 (UTC)
 * "New"?? The week starting on Sunday dates to prehistoric times.  The week starting Monday is a novelty introduced in the 20th century.  I don't think there's any English-speaking country where it's considered standard. Michael Hardy (talk) 02:07, 20 March 2009 (UTC)
 * I meant "new" in the sense of "different from what had been done before on this particular page". My point was about the move from using the template to having the calendar as explicit text, rather than the Sunday/Monday issue which we've already debated.  I think the template used previously was clear and well laid out but that is one opinion amongst many and I hope to hear other people's thoughts.  Certes (talk) 13:36, 20 March 2009 (UTC)
 * Now, I went to Template:Year3 and it said that the "start-on-Monday" week comes from Template:Month3, which in turn I still cannot find where it comes from. Georgia guy (talk) 14:52, 20 March 2009 (UTC)
 * I found the best template to use, Template:CalendarCustom. Georgia guy (talk) 14:59, 20 March 2009 (UTC)
 * Good work. Does anyone object if we change this page again to use Template:CalendarCustom?  As my contribution to the civil consensus, I propose we keep its default of Sun1st for now but consider changing to Mon1st if a majority of people object. Certes (talk) 18:23, 20 March 2009 (UTC)
 * I have no objections to either the CalendarCustom template or the weeks starting on Sunday. Georgia guy (talk) 19:24, 20 March 2009 (UTC)
 * Well, now that I have seen the planned Template that you wish to put in I feel I have no objections, and personally I prefer calenders that have weeks starting on Sundays than on Mondays anyway. Nohomers48 (talk) 22:09, 21 March 2009 (UTC)

Clearly we need a format where we can link to the dates.

This discussion doesn't seem to be attracting a broad range of commentators; I surmise that not many people pay attention to this page, and I'm not that surprised.

What would be the best way to get a large number of other informed people who may have views on this into this discussion, if that should prove to be the prudent thing to do? Michael Hardy (talk) 19:28, 20 March 2009 (UTC)
 * You could try WP:RFC but I don't think you need to. These articles get a very low number of hits so I don't think you'll get much input - or objection.  If you've got a basic consensus, you can use edit-and-wait to confirm it.  I'm not sure of their true utility.  But I think CalendarCustom is similar enough to the previous format with the added ability to set the starting day and the only objection will come from those who feel the need to see the week number.  -- Mufka (u) (t) (c) 14:20, 21 March 2009 (UTC)

Many articles have links like 2007 to a page beginning "2007 (MMVII) was a common year starting on Monday..." or similar, so this page is two clicks away from much of the encyclopedia. (with a suitable year specified for Tue-Sun starts and leap years) is almost what we need, if we can remove the specific year from the heading. Certes (talk) 20:02, 21 March 2009 (UTC)
 * I added an option to Calendar so that you can hide the year. Use  .  That template uses CalendarCustom, BTW.  -- Mufka (u) (t) (c) 23:46, 21 March 2009 (UTC)
 * Thank you Mufka. So if we use Calendar|hideyear, the main differences between the old (27 July 2007 to 19 March 2009) and future versions will be:
 * remove week numbers
 * start on Sunday rather than Monday (with option to revert if opposed by consensus)
 * minor formatting differences such as adding < > links to previous and next month
 * Does that sound like a solution? Certes (talk) 19:31, 22 March 2009 (UTC)

No progress
This page is hopelessly neglected. It's been months since I raised the issue of the conspicuous error on this page&mdash;that it has weeks starting on Monday instead of Sunday. But all we see is an edit, just today, which I reverted, saying there's no accuracy dispute. (I'd quickly clean up the mess myself if it did not appear necessary to have extensive familiarity with certain kinds of software. I did clean it up once, but without links to each date, etc., and that got reverted.) Michael Hardy (talk) 08:21, 20 November 2009 (UTC)

 * The other 13 pages have issues which are so similar that it makes sense to discuss them all in one place.

Some of the other talk pages have links to here and could possibly be replaced by redirects to here. Certes (talk) 11:35, 22 January 2010 (UTC)

Sunday at the End?
I suppose there is a reason why this calendar ends with Sunday, although for two thousand years and more, Sunday has been the first day of the week. What is the reason? L.ThomasW. —Preceding unsigned comment added by 24.140.12.27 (talk) 20:05, 8 September 2010 (UTC)

Changing the calendar at last
Reading through this pages it seems to me that the vast majority are in favour of using a Sunday-first calendar on these pages. I agree, it's the more common format used in English-speaking countries. There was a suggestion above though that we might like to make it optional. If that's what we want, then we could use hidden i.e. something like this.

 * No,, it’s just that it used to be Monday-first as in all relevant international standards and that puzzled several users independently, so they raised their voice here – I can assume at best that most of them are from the US. In many other places (primarily English speaking or not), people are used to encounter Monday-first print and electronic calendars (i.e. with both weekend days at the end of the week), although they’re quite likely to also have seen Sunday-first calendars, because a) that used to be the standard in many places, b) is still used in Christian churches and c) is used in badly localized products designed in or for the US market. Remember that enWP is read by a lot of people who learned English as a second language, perhaps they’re even more than native speakers. I for one found the current solution strange and edited Common year starting on Sunday today to include both variants, in a way similar to what you suggested back in 2013, but without hidden – before I looked at the Talk pages, which I then combined, so prior discussions are less likely to be overlooked. I decided that the “international” calendar layout should use week numbers according to ISO 8601, but the English/US variant could remain without. This also resulted in changing the layout from 3→×4↓ to 4→×3↓ (i.e. first left to right then top to bottom), although I think 3↓×4→ would be even clearer if visible at once. — Christoph Päper 20:30, 20 May 2016 (UTC)


 * The seven-day week came from the Babylonians via the Jews and then the Christians. According to ancient tradition, Sunday is the first day of the week (God is said to have rested on the seventh day, Saturday, the Jewish sabbath).  I'd say that ancient tradition is a relevant international standard.  Sure, much can be attributed to religious influence and WP is a non-religious medium but, nevertheless, it has shaped the way we thing of the week.  Therefore, Sunday-first calendars are the more common form in English-speaking countries (not just the US).  So, what it actually used to be (for thousands of years) is Sunday-first and Monday-first calendars have yet to catch on to the extent of over-taking the older's prominence in English.  As for those for whom English is a second language, let them get used to the way we do things in English.  This is not to regard them as any less important, valuable or worthwhile; it's just part of learning the language to get used to how things are done in it. Jimp 06:57, 21 May 2016 (UTC)
 * Please don’t get me wrong, I’m not arguing in favor of completely reverting to Monday-first, because it seems obvious that this confuses or annoys some people, but Sunday-first does too. I don’t want to create 14 or 15 separate Common/Leap ISO year starting on …day articles.
 * Just for the sake of reference I quote below a part from Unicode CLDR’s supplementalData.xml. The data can also be viewed in tabular fashion or per locale (language/country). CLDR lists GB (with a deviating variant) and default  as Monday-first, but most major English-speaking areas like AU, CA, IE, IN and US as Sunday-first (Ireland was changed in 2012). Also note the ISO way of week numbering   is still applied to Ireland, but not to the default code. — Christoph Päper 08:37, 21 May 2016 (UTC)

Comment on these pages
Bearing in mind that Wikipedia is not an indiscriminate collection of information, should these articles really exist? I don't think it's encyclopaedic, and if people really did want to know about it would wikipedia really be the place they'd look? Perhaps there is scope to merge one of them into another article (perhaps Gregorian calendar?) as an example, but I'm not convinced that all fourteen of them are really necessary as seperate articles.

2101, 2107 and missing a day
I’m trying to find a calendar that 2101 and 2107 starts on a Sunday, but rather it starts on Saturday

2073, 2079, and 2090 all start and end on Sunday 2084 is a leap year it starts on Saturday and ends on Sunday 2096 is a leap year it starts on Sunday and ends on Monday

1973, 1979, 1990, 2001, and 2007 all started and ended on Monday 1984 was a leap year started on Sunday and ended on Monday (follows same calendar as 2096) 1996 was a leap year started on Monday and ended on Tuesday (should’ve followed the same as 2108)

When I try  gives an output as   adds a day. Same applies with  gives an output as   adds a day.

July 7, 2107 is a rather than a Friday which occurs in 2073, 2079, and 2090. July 8, 2107 is a rather than a Saturday which occurs in 2073, 2079, and 2090.

Is there a year that is no leap year, that breaks the sub-28 cycle?

 * Yes, the 28-year cycle is broken because 2100 is not a leap year. The years 2073, 2079, 2090, and 2096 (a leap year) all start on Sunday; while adding 28 years to them give 2101, 2107, 2118, and 2124 (also a leap year) respectively, which all start on Saturday.

Concerning the table of example years.

I consider it too big for the information it contains, not worth the scrolling and waiting.

I prefer the previous century per row table.

I see no need for links to millennia in the table and I do not think links to decades are important enough here to justify making the table 10 times longer.

Or why not just list the example years (e.g.) 1803 1814 1825 1831 1842 1853 1859 etc.

Also not being in a HTML tabler form backs it easier for users to correct or extend (e.g. to full 400 years).

New unusual format overruns small screens
07-Jan-2008: I had thought the various year-starting calendars were stable, since the concept has been around hundreds of years. Of course, I forgot "form over substance" would likely re-write the calendars into another format. Now, I notice that the new format is totally incompatible with 800x600 resolution screens, scrolling beyond the right margin for the display of something as trivial as a full-year calendar. Wikipedia continues to be plagued with garbled, weird display pages: as soon as an article gets carefully typeset for a wide range of user screens (and various browsers), the page is replaced. Now these overwide full-calendar pages have highly spastic "week numbers" appended to each week in a very queer and wiki-peculiar innovation. No original research: do not display a calendar in bizarre "new research" format. Stick to calendars that look normal, as I think they did last year. The concept "NO ORIGINAL RESEARCH" means no displaying of "standard" Gregorian Calendars with queerly spastic, peculiar week-number displays. I think these calendars need to be reverted, per WP:NOR. -Wikid77 (talk) 00:32, 7 January 2008 (UTC)

Incorrect calendar
I've commented out the calendar because it is greatly in error, i.e. missing several days which in turn makes the rest of it inaccurate. I figured it was better to have no calendar than one that is wrong, especially considering that the average user would not have noticed the error. I'd fix the mistake myself but that HTML looks daunting. --Polynova 07:55, 27 Nov 2004 (UTC)

Why does age templates output invalid dates as errors?, as  in a non-leap year is an invalid date,   in a leap year is a valid date.

 * I am not familiar with the code that implements the ayd template, but it is likely that it passes the date to some function that either returns a date the template can work with, or returns an error message. The various functions do not necessarily have any ability to provide a "close" answer, or convert the date into one that actually exists, such as March 1, 2100. So I am not a bit surprised at the error code.


 * Just in case you weren't aware, in the Gregorian calendar (which is what all the date-related functions I know of in Wikipedia work with) a year that is evenly divisible by 100, but not by 400, is a common year, so 2100 is a common year. Jc3s5h (talk) 16:18, 30 July 2019 (UTC)

New unusual format overruns small screens
07-Jan-2008: I had thought the various year-starting calendars were stable, since the concept has been around hundreds of years. Of course, I forgot "form over substance" would likely re-write the calendars into another format. Now, I notice that the new format is totally incompatible with 800x600 resolution screens, scrolling beyond the right margin for the display of something as trivial as a full-year calendar. Wikipedia continues to be plagued with garbled, weird display pages: as soon as an article gets carefully typeset for a wide range of user screens (and various browsers), the page is replaced. Now these overwide full-calendar pages have highly spastic "week numbers" appended to each week in a very queer and wiki-peculiar innovation. No original research: do not display a calendar in bizarre "new research" format. Stick to calendars that look normal, as I think they did last year. The concept "NO ORIGINAL RESEARCH" means no displaying of "standard" Gregorian Calendars with queerly spastic, peculiar week-number displays. I think these calendars need to be reverted, per WP:NOR. -Wikid77 (talk) 00:33, 7 January 2008 (UTC)

The clearly confirmable actual fact of the exact identitiy of the periods within any period of four centuries in the Gregorian calendar
Can I together of course with others do otherwise than clearly admire the works of those who have taken such trouble on this matter?

Ladies and gentlemen, unfotunately it seems you do not take into account the fact that as I have stated at the headline of this my own contribution on this Talk Page all four hundred years are exactly identical in this form of what is now to some extent international calendars.

What is possibly related is the fact that unfortunately I have not seen this clearly confirmable fact made identified on Wikipedia or indeed perhaps anywhere else but personally I think it must have been clear at the time that this form of calendars was first created in Europe in the 16th century.

The immediate issue is the period of six days in addition of weeks in the century in the last year of 99 before the century in the years divisible by four hundred and of five days in the same issue in the following three centuries this being of course a total of twenty-one days that which is divisible by seven (or weeks) and with the final century in the four hundred year section carried one day ahead from the centuries divisible by four hundred (such as 17th or the present 21st centuries) this being with any similar form at the commencement of what is any such four centuries.

This is I suggest (even if not perhaps particularly well explained by myself here and not directly explained so far as I am aware anywhere else) a fact which cannot I believe be denied and I very much hope that eventually it is something that will become better known generally.

Slow motion edit war over display of years
On Leap year starting on Wednesday, the calendar is currently created with. In early January of this year, there was a slow motion edit war over the show_year parameter (and, less controversially, year was changed from 1964 to 2020). As far as I can tell, neither side used edit summaries or otherwise discussed this change, and it's currently still set to off. Do we have a guideline or precedent for this, or should we come up with one now? I'd rather not have this fight again every January 1. The basic problem, of course, is that the template merely appends "2020" to the prose title, which looks nonsensical. But that could be overcome with a simple copyedit. And of course, if we're going with "leave it the way it is," we might want to throw in an HTML comment telling people not to change it. -- N Y  Kevin   03:05, 14 January 2020 (UTC)

1810 and 1900
The table in this article says 1810 is in the second decade of a century but 1900 is in the tenth decade of a century. This means they're 8 decades apart; they have to be 9 decades apart because they have the same final digit and are exactly 90 years apart. Georgia guy (talk) 13:05, 1 June 2021 (UTC)

listing multiple years rather than the most recent and the next
The statements "The most recent year of such kind" and "The next one will be" only require one year, not two, to be listed for each. Meters (talk) 08:24, 24 July 2022 (UTC)

10th decade
In the table near the bottom of the article dealing with the Gregorian Calendar, it says that 1990 and 1900 are both in the tenth decade of their respective centuries. This makes no sense unless you're saying a decade can have 11 years. Georgia guy (talk) 15:43, 3 October 2022 (UTC)
 * There is an inconsistency in the table. It appears that the table treats decades as running from year 0 to year 9, not year 1 to year 10 (thus putting 1770 and 2170 in the 8th decades rather than the 7th), but centuries as running from year 1 to year 100 (putting 1900 in the 19th century, and 2300 in the 23rd century). Both systems are used, but we shouldn't mix them in one table. See Decade and Century. Meters (talk) 18:51, 3 October 2022 (UTC)

Too USA orientated

Note on calendar choice
The "Leap year starting on a ..." and "Common year starting on a ..." articles all contain an editing note starting with "To avoid arbitrary years, use the most recent or upcoming year of this type." Since there is still too much edit churning between the most recent and the upcoming years (for example, see, , , , , , , , , , by an IP today), I suggest that we eliminate the option of choosing which to use. We should either use "most recent", or we should use "upcoming". No choice.

I think the most recent such year is the best choice since some of the upcoming years are far enough in the future that we don't have year articles for them. Meters (talk) 22:47, 11 February 2023 (UTC)
