Frequently asked questions

Q1: Why is [Insert event here], an event that is "more important and significant" than all the others that are currently listed, not posted?: A1: Relative article quality along with the mix of topics already listed are often deciding factors in what gets posted. Any given day of the year can have a great many important or significant historical events. The problem is that there is generally only room on the Main Page to list about 5 events at a time, so not everything can be posted.

As stated on Wikipedia:FAQ/Main Page, the items and events posted on the Main Page are chosen based more on how well they are written, not based on how much important or significant their subjects are. It is easier for admins to select a well-written, cited, verifiable article over a poor one versus trying to determine objectively how much a subject is important or significant.

Keep in mind that the quality requirements only apply to the selected bolded article, not the other links. Thus, an event may qualify for multiple dates in a year if there is an article written in a summary style and an article providing detailed content; if one of those pages have cleanup issues, the other page can be bolded as an alternate.

Another criterion is to maintain some variety of topics, and not exhibit, just for example, tech-centrism, or the belief that the world stops at the edge of the English-speaking world. Many days have a large pool of potential articles, so they will rotate in and out every year to give each one some Main Page exposure. In addition, an event is not posted if it is also the subject of this year's scheduled featured article or featured picture.

Q2: There are way too many 20th-century events listed. Why aren't there more events from the 19th century and before?

A2: The short, basic reason is the systemic bias of Wikipedia. There are not enough good, well-written articles on 19th-century and earlier events for all 365 days in the year. Currently, a majority of users seem to be generally more interested in writing articles about recent events. If you would like to further help mitigate the systemic bias in Wikipedia, see Wikipedia:WikiProject Countering systemic bias.

Q3: This page seems to be biased toward events based in [Insert country or region here]. What can be done about it?

A3: This again is attributed to the systemic bias of Wikipedia. Many users are generally more interested in working on good, well-written articles pertaining to their home country. Since this is the English Wikipedia, there will be more English-speaking users, and thus more articles pertaining to English-speaking countries. And if there are more users who are from the United States, there will probably be more well-written articles about events based in the United States. Again, if you would like to further help mitigate the systemic bias in Wikipedia, see Wikipedia:WikiProject Countering systemic bias.

Q4: Why is the birthday/death anniversary of [Insert name here] not listed?

A4: There are only four slots available for birth and death anniversaries. As with the events, article quality and diversity in time period, geography, and reason for notability are all contributing factors in whether an article gets selected for inclusion.

Q5: Are the holidays/observances listed in any particular order?

A5: Yes, there is a specified order: International observances first, then alphabetically by where observed.

Q6: Some of the holidays/observances that are listed have dates in parentheses beside them. What do they mean?

A6: There are two reasons that some holidays/observances have dates next to them:

Non-Gregorian-based holidays/observances are marked with the current year as a reminder to others that their dates do in fact vary from year to year.
National Days, Independence Days, and other holidays celebrating the nationhood of a country are generally marked by the year of the significant historic date being observed.

playstation 3 is released in japan!!! this should be here somewhere?

Leibniz

It is frustrating to have to return to this page repeatedly to fix this same stupid statement. It is frustrating to have one's kindness to others repeatedly answered by saying that when I try to patiently explain to them what (literally) normal (literally) 15-year-olds are (literally) required to understand I am writing in a manner that could only be understood by advanced mathematicians who already know the idea I am trying to express. When I say literally I mean: look at the textbooks that 15-year-olds are told to read. Look at them. LOOK AT THEM. Before lecturing me about this.

I fixed this same incredibly stupid mistake on this page several years ago after I saw it getting ridiculed at Wikipedia talk:WikiProject Mathematics.

Why was my fix reverted? Will it be necessary to return each year to do this again? Michael Hardy (talk) 17:09, 11 November 2008 (UTC)[reply]

Your fix seems to have survived. However, the Gottfried Leibniz page has "y=x". I'm not going to fix it because it's apparently a hot topic, and there may be ramifications that I don't understand. --Heron (talk) 21:46, 11 November 2008 (UTC)[reply]

In answering Michael Hardy's question about "Why was my fix reverted?", I looked at the page history and it seemed to have been previously removed in 2006 for reasons I do not necessarily agree with now.[1] I added the Leibniz event back a couple of days ago, [2], but like any other thing I add to the OTD pages, I basically copy and paste the same spelling and notation from the relevant articles (see also WP:ENGVAR). Since Gottfried Leibniz#Calculus had that "y=x" notation at the time,[3] that was the notation that ended up being copied and pasted. Cheers. Zzyzx11 (Talk) 05:24, 12 November 2008 (UTC)[reply]

I made exactly the same mistake as you, Z. I saw the "y = f(x)" on the anniversary page and the "y = x" on the Leibniz page, thought "ah, transcription error" and changed "y = f(x)" to "y = x". Minutes later I saw Michael's (perhaps justified) rant on the subject and reverted my edit before anyone noticed. I think there is an underlying problem here that hasn't been fixed yet. The wording on the anniversary page is confusing, and occasionally leads people to suspect an error where there isn't one. The statement:

employed integral calculus for the first time to find the area under a function y = ƒ(x)

doesn't sound like good maths. What is the point of the "y = f(x)"? We've already stated that he integrated a function, so the functional notation is redundant. It looks as if it's been put there to make the sentence look more impressive without adding any meaning. Who cares if he integrated y = f(x) or glork = frimp(spog)? A function is a function. Maybe the sentence is trying to say that he was the first to use the notation ∫ f(x).dx, or ∫ y.dx where y = f(x). If that's the case then why don't we say so? It would stop people from trying to correct it, and would save Michael some frustration. --Heron (talk) 09:52, 12 November 2008 (UTC)[reply]

St. Martin's Day

Since when is this day only relevant to the Netherlands? Seems like half of Europe considers it fairly important.

Peter ^Isotalo 20:57, 11 November 2009 (UTC)[reply]

It's now fixed. Thanks, Peter. --PFHLai (talk) 09:48, 10 November 2010 (UTC)[reply]

US Numbered Highway System

The final plan for the United States Numbered Highway System was approved on November 11, 1926, and the system debuted on that date. This year (2011) will make the 85th anniversary, so I'm nominating it for inclusion in the list. (I added it to the list of eligibles on the page.) Imzadi 1979 → 02:17, 22 October 2011 (UTC)[reply]

"You forgot Poland"

I would like to remind that today there is a National Independence Day also in Poland (1918). Please check an article. Can it be added now, when the section is on the Main Page? 83.10.124.41 (talk) 14:01, 11 November 2011 (UTC)[reply]

I see that this event is "ineligible" because of no resources (click here). So, instead adding a link to the Independence Day article, you can check it here, here or here and just link to the article about Poland (as in the case of Angola). 83.10.124.41 (talk) 14:27, 11 November 2011 (UTC)[reply]

It seems strange to list Veterans Day (U.S.), but not Remembrance Day, which is a very wide-spread observance by comparison. Why was this left out? I have read the Remembrance Day article and it seems quite well-written. Markcymru (talk) 03:02, 11 November 2016 (UTC)[reply]

@Markcymru: The Mauritius section of the Remembrance Day article has no references, and per the rules, we cannot include articles with this type of maintenance tag. —howcheng {chat} 07:10, 11 November 2016 (UTC)[reply]

Edit request 2018

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

Change the reference (at least for today, while it's on the main page) to the US-only "Veterans day" to a more global "100th anniversary of the Armistice of 11 November 1918" (and remove the ensuing duplicate, keeping the picture). Only fitting... 107.190.33.254 (talk) 15:56, 11 November 2018 (UTC)[reply]

Not done .254, You will need to establish a consensus for this change prior to it being enacted via an edit request. Talk:Main_Page#Errors_in_today's_or_tomorrow's_On_this_day could be a good place to start if you think the event has undue weight. — xaosflux ^Talk 17:29, 11 November 2018 (UTC)[reply]

@Xaosflux: And what of the friendly suggestion on the page that "To suggest a new item, in most cases you can be bold and edit this page." ?? Anyway, posted to the relevant place. 107.190.33.254 (talk) 17:40, 11 November 2018 (UTC)[reply]

The rest of that statement points out specifically a difference for what this is on the main page, I suggested Talk:MP instead of here since there are only a few hours left where this will be visible and you would get the most attention there. In a day and a half it will be unprotected and you can try some bold edits to prep for next year. Best wishes, — xaosflux ^Talk 19:51, 11 November 2018 (UTC)[reply]

Thanks, my bad for not reading through to the end. 107.190.33.254 (talk) 20:34, 11 November 2018 (UTC)[reply]

Normally we would include Remembrance Day, except that article is currently ineligible. —howcheng {chat} 07:22, 12 November 2018 (UTC)[reply]

That doesn't fix the wider issue, that all of these names are specific to only a few regions (WP:Systematic bias), while saying "Anniversary of the Armistice of 11 November 1918" includes everybody (UK, Canada, US, Australia, even non-English-speaking countries,...). The only major lack of that article (in this context) is that there's only a few sentences about the celebrations of the Armistice, (i.e. the Legacy section), but it's arguable how much we should include in there, or if we should expand the other articles instead. 107.190.33.254 (talk) 14:49, 12 November 2018 (UTC)[reply]
