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 August 13, 2024

The national flag of Japan is a white rectangular flag with a large red disc (representing the sun) in the center. It is officially called Nisshōki in Japanese, but more commonly known as the Hinomaru. Although considered the de facto flag, it was designated as Japan's national flag on August 13, 1999. In early Japanese history, the Hinomaru motif was used on flags of daimyos and samurai. During the Meiji Restoration both the sun disc and the Rising Sun Ensign were symbols in the Japanese empire. Use of the Hinomaru was restricted during the American occupation after World War II, but this was later relaxed. The flag is not frequently displayed due to its association with extreme nationalism. For nations occupied by Japan, the flag is a symbol of aggression and imperialism. Despite negative connotations, Western and Japanese sources claim that the flag is an enduring symbol to the Japanese. (This article is part of a featured topic: Act on National Flag and Anthem (Japan).)

Picture of the day for August 13, 2024

The royal angelfish (Pygoplites diacanthus) is a fish in the marine angelfish family, Pomacanthidae. It is found in tropical seas, including the Red Sea and Indian Ocean around East Africa and the Maldives, the Tuamotus, New Caledonia, and the Great Barrier Reef. It is also found around Taiwan and islands off the coast of Japan. The fish has a maximum length of 25.0 cm (9.8 in), with a coloration varying by region. A commonality is that the body is edged in narrow blue-white and orange stripes that are narrow and angle backward. It is a carnivorous species, feeding on sponges and tunicates, and resides in coral rich areas of lagoons and reefs as well as in the vicinity of caves. This royal angelfish was photographed in Ras Muhammad National Park on the Sinai peninsula, Egypt.

Berlin Wall - 50 years anniversary not included .... WTF

It's 50 years today since the GDR started to build the Berlin wall ... and that's not included in OTD ...? — Preceding unsigned comment added by Michael Zimmermann (talk • contribs) 08:51, 13 August 2011 (UTC)[reply]

The Berlin Wall article contains several sections that have no references and per the rules at WP:OTD is therefore ineligible. howcheng {chat} 17:28, 13 August 2011 (UTC)[reply]

Why no mention of this on OTD??? Kiwibeca (talk) 16:16, 13 August 2011 (UTC)[reply]

@Howcheng: IMO this a better crop of Philippe de Champaigne's portrait of Richelieu: File:Cardinal de Richelieu (detail).jpg. Would you consider changing it? Ham II (talk) 07:02, 13 August 2016 (UTC)[reply]

@Ham II: I think current picture has better colors. The one you suggest is fairly muted. Of course, I have no idea which is a more accurate representation of the real painting. —howcheng {chat} 07:24, 13 August 2016 (UTC)[reply]

@Howcheng: The alternative crop is taken from this featured picture and is closer to the colours of the real painting; cf. the National Gallery's website. Ham II (talk) 07:30, 13 August 2016 (UTC)[reply]

2023 rationale

The 1779 fact has multiple {cn} tags so I avoided adding it.
There is an overwhelming number of sea-related facts.
I chose the 2010 fact over Opha May Johnson, due to both being about marines and another sea incident.
Good mix of b/d with anniversaries!
