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.

Today's featured article for December 12, 2024
Polynomial equation studied in elementary algebra Algebra is the branch of mathematics that studies certain abstract systems, known as algebraic structures, and the manipulation of statements within these systems. Elementary algebra generalizes arithmetic by using variables in addition to numbers. It covers methods of transforming equations to solve them by isolating variables. Linear algebra examines systems of several linear equations and techniques to determine for which values all equations in a system are true at the same time. Abstract algebra investigates algebraic structures, which consist of a set of objects together with operations defined on that set. It distinguishes algebraic structures, such as groups, rings, and fields, based on their number of operations and the laws they follow. Algebraic methods were first studied in ancient times to solve specific problems. As algebra evolved, it became increasingly abstract and generalized, leading to many applications in other branches of mathematics and the empirical sciences. (Full article...)

I think Paul Martin's becoming Prime Minister of Canada in 2003 is worthy of mention here, afterall their have only been 21. I think it is more noteworthy than the Panay Incident, which I had never heard of until reading here, though I had heard of the other three items. Thoughts on this? I'd like to change this before December 12 if there is no objection. - Jord 00:58, 9 Dec 2004 (UTC)

I'll pass. It remains to be seen if Martin is going to be a notable PM in Canadian history or not. And we should avoid featuring him while he is campaigning for the federal election. -- PFHLai 08:37, 9 December 2005 (UTC)[reply]

Clapham Junction rail crash

http://en.wikipedia.org/wiki/Clapham_Junction_rail_crash

Any reason why this deserves less merit than the others listed? It was a while ago (but so were the others listed) but it was one of the worst in the UK and I believe it has merit to be listed still. 87.194.84.44 (talk) 13:50, 12 December 2011 (UTC)[reply]

It doesn't have enough footnotes. See WP:OTD#Criteria for listing items on this set of pages #8. howcheng {chat} 20:07, 12 December 2011 (UTC)[reply]

I've rewritten it, but I suggest that it's run in 2013 as this is the 25 year anniversary. Edgepedia (talk) 18:00, 12 October 2012 (UTC)[reply]

Centennial of Frank Sinatra's birth

I am not sure of the proper manner in which to make this nomination, but the 100th anniversary of Frank Sinatra's birth (December 12, 1915) occurs this year. Based upon his accomplishments as an entertainer, he seems to be a viable candidate for listing in this year's OTD/SA. --Allen3 ^talk 14:25, 4 November 2015 (UTC)[reply]

FYI, DYK has organized an effort to fill the December 12 sets with Sinatra hooks. --Allen3 ^talk 21:56, 29 November 2015 (UTC)[reply]

OK, we'll leave Sinatra out then. Thanks. —howcheng {chat} 03:21, 10 December 2015 (UTC)[reply]

@Howcheng: DYK is not specifically mentioning the anniversary under the suggestion that it is more suited to OTD? Is there an issue with it running in tandem? --Errant ^(chat!) 11:43, 10 December 2015 (UTC)[reply]

Usually we don't duplicate efforts between sections. If a subject is featured in TFA/POTD, we wouldn't list it in OTD either. I would think the same rule applies to DYK, but I don't remember having done this before. —howcheng {chat} 16:53, 10 December 2015 (UTC)[reply]

Hi @Howcheng, do you know who added Musikhjalpen to today's top of the box? I would like to object to its inclusion on the grounds of significance and poor article quality. QueensanditsCrazy (talk) 16:30, 12 December 2022 (UTC)[reply]
