Wikipedia talk:Selected anniversaries/December 13

The 1981 event should probably point to Martial law in Poland. That is the article about the actual event, as opposed to Martial law, which describes what it is in general. --daranzt 15:47, 13 December 2006 (UTC)

Dartmouth
Is not really Royally Chartered. The only two royally chartered colleges in the US are Columbia and William & Mary. Dartmouth's charter is signed by the governor, on behalf of the crown, but not by the crown. Savidan 21:23, 13 December 2010 (UTC)
 * I'm sorry, I don't quite understand how we can qualify the statement in order to be accurate in the way that you mention. Can you suggest an alternative wording?  howcheng  {chat} 22:24, 13 December 2010 (UTC)
 * Dartmouth, and the rest of December 13, is now off the Main Page. I presume it's unprotected, so you can fix it for next year. Art LaPella (talk) 00:52, 14 December 2010 (UTC)

2011 notes

 * Swapped in: Battle of Alton (first appearance), Ephraim McDowell (first appearance), Nanking Massacre (4th appearance, last in 2008, recovered from Ineligible), Wojciech Jaruzelski (6th appearance, last in 2009, recovered from Ineligible)
 * Left in: 1960 Ethiopian coup attempt (2nd consecutive appearance, 2nd overall)
 * Deliberately did not use Battle of Fredericksburg, despite its omission last year, to avoid having three war articles.

2012 notes

 * Omitted: Battle of Alton; Ephraim McDowell; 1960 Ethiopian coup attempt; Wojciech Jaruzelski
 * Included: Francis Drake (9th appearance, last in 2008); National Guard of the United States (first appearance); Battle of Fredericksburg (6th appearance, last in 2009; 150th anniversary); 2001 Indian Parliament attack (2nd appearance, last in 2010)

 * Omitted: Francis Drake; National Guard of the United States; Battle of Fredericksburg; Nanking Massacre; 2001 Indian Parliament attack
 * Included: Council of Trent (7th appearance, last in 2010); Ephraim McDowell (2nd appearance, last in 2011); 1960 Ethiopian coup attempt (3rd appearance, last in 2011); Attack on Derryard checkpoint (first appearance); 2011 Liège attack (first appearance)

Another suggestion is 13 December 1981 when General Jaruzelski declared martial law, suspended Solidarity and imprisoned many union leaders. I THINK THIS IS VERY IMPORTANT. -TrainSimFan

Arba'een
Arba'een is added. While Arba'een is always on the same day of the Islamic calendar, the date on the Gregorian calendar varies from year to year due to differences between the two calendars, since the Islamic calendar, the Hijri calendar (AH), is a lunar calendar and the Gregorian calendar is a solar calendar. Furthermore, the method used to determine when each Islamic month begins varies from country to country (see Islamic calendar). Arba'een this year, coincides with 13 December in many countries such as Iraq. Mhhossein (talk) 09:48, 10 December 2014 (UTC)

Edit war by Joseph
Please notice that User:Sir Joseph is edit warring on this page. He has reverted all of my house keepings. -- M h hossein   talk 19:29, 11 December 2017 (UTC)
 * Reverting you is not edit warring. You are the one who didn't abide by BRD. Sir Joseph (talk) 20:05, 11 December 2017 (UTC)
 * And you came to be wrong as Howcheng said, not Bold. -- M h hossein   talk 07:13, 12 December 2017 (UTC)
 * That's not how BRD works. And is there a reason why you are so aggressive with this entry? Sir Joseph (talk) 16:35, 12 December 2017 (UTC)

OK, let's cool it down here. , this is standard operating procedure for OTD updates. We usually vet the articles 1-3 days in advance of their main page appearance. If we do it too late, then we get complaints that there wasn't enough time for editors to fix any problems, and if we do it too early, then basically you have to do it again later in case any changes were made. A few days ahead of time seems to be the optimal balance. As I said to you elsewhere, if you have an issue with specific article(s) (such as in this case), then please limit the scope of your revert so that other cleanup is not affected. the Jewish holidays are kind of a special case because WikiProject Judaism is fairly proactive in fixing issues when they are made aware of them. SJ specifically came to me about this article to let me know they were working on it, so we can let this get handled at WP:ERRORS if it's not done in time. Thanks. — howcheng  {chat} 16:59, 12 December 2017 (UTC)
 * OK, I'm OK with that. I do think however that some of the tagging is extremely nitpicky and overly aggressive. Our goal should be to have articles on the front page, not to exclude them. If there are glaring issues, then yes, it might not belong, but on the flip side, having articles on the page allow more people to edit and fix issues. Sir Joseph (talk) 17:02, 12 December 2017 (UTC)
 * Thanks for the intervention Howcheng. Reverting all what I had done was sort of annoying edit. SJ could simply resolve the issues instead of these reverts. I do my best to to keep the main page clean. -- M h hossein   talk 18:29, 12 December 2017 (UTC)
