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.

2015 unrequest

As much as Phineas Gage is my pet topic, I recognize overexposure isn't a good thing, so I suggest he be rotated out this year. Howcheng, let me mention in passing that I doubt you get the recognition you deserve for your consistent hard work at OTD. If only DYK ran so smoothly! EEng (talk) 16:53, 9 August 2015 (UTC)[reply]

2016 Request

Howcheng, can we have Phineas Gage back (but no image, for reasons that should become clear in the next year or so)? E Eng 21:13, 7 September 2016 (UTC)[reply]

@EEng: Sure, let's get him back in. —howcheng {chat} 16:01, 8 September 2016 (UTC)[reply]

Weird... I can't remember what the reasons "that should become clear in the next year or so" were for not using the image. E Eng 23:07, 13 September 2018 (UTC)[reply]

I guess the reasons didn't become clear, then! :) —howcheng {chat} 06:27, 14 September 2018 (UTC)[reply]

2018 query

Hi Howcheng, Petros Voulgaris article has 1884 as year of birth 3 times (lede, infobox, category) but the only referenced (Ref 2) date of birth at section Life has 1883. (Ref 1 per infobox doesn't help.) Should all (and main page) change to 1883? Thanks for all you do. JennyOz (talk) 03:26, 12 September 2018 (UTC)[reply]

@JennyOz: It looks like 1883 is correct, per [1] .. not sure how reliable that is, but "Πολιτιστικό Ινστιτούτο" (the text next to the copyright notice) translates to "Cultural Institute". I didn't find anything that said 1884 except for WP mirrors. —howcheng {chat} 07:13, 12 September 2018 (UTC)[reply]

Thanks Howcheng, I adjusted birth year category too, Regards, JennyOz (talk) 07:42, 12 September 2018 (UTC)[reply]

@JennyOz: It turns out that my reference was no good after all, because it put his birth date as 13 July. I think the Greek Navy can be trusted to correctly state the biographical details of one its long-serving officers. —howcheng {chat} 17:16, 12 September 2018 (UTC)[reply]

All good, thank you, JennyOz (talk) 04:03, 13 September 2018 (UTC)[reply]
