These are the supplementary rules (formerly called additional rules or unwritten rules) of Did You Know; that is, they are supplementary to Wikipedia:Did you know#DYK rules and Template talk:Did you know#Instructions for nominators. These rules provide detailed explanations for commonly asked questions regarding the basic rules. It is not necessary to be thoroughly familiar with every one of these rules, but if you have a question regarding interpretation of the basic rules, you will probably find the answer here.

These rules are meant (as said in G4 below) to describe consensus that has been reached among the DYK community through previous discussions of issues that have come up repeatedly.

Supplementary article length rules[]

Supplementary article link rules[]

Other supplementary rules for the hook[]

... that Luciano Berio based '''''{{lang|it|[[Quattro versioni originali della "Ritirata notturna di Madrid"]]}}''''' on Boccherini's ''{{lang|it|[[Musica notturna delle strade di Madrid]]}}''?
In the example, it is the code for Italian. Other common codes are fr=French, de=German, la=Latin, es=Spanish; see List of ISO 639-1 codes. Note also the use of '' for italics and ''''' for bold-italics.

Other supplementary rules for the article[]

"Rules" sometimes invoked but lacking a consensus[]

Rules listed elsewhere but often overlooked[]

Other recurring issues[]

To explain Step 2, which might seem counter-intuitive, the difference between an 's change, which you see by clicking "last" on the history page, and an 's result, which you see by clicking the time stamp on the history page. Although an 's change and result are listed on the same line, the change really comes between that result and the previous 's result. Similarly, a result comes between that 's change and the next 's change, even though a change and a result are shown on the same line.
Example. On January 1, 2006 a 100 character stub is created. At 1:00 on July 18, 2008, the 100 characters are expanded to 1000 characters. An hour later at 2:00 July 18, 2008, the article is further expanded to 2000 characters. Putting it that way, the expansion is clearly 20× and qualifies for DYK. But to count the 100 characters, they wouldn't be listed as 1:00 July 18. The 100 characters existed on July 18 before 1:00, but the 100 characters were the result of the previous . So you would have to click the 2006 to count the 100 characters, even though 2006 is much too old for DYK. If you made the mistake of clicking the first for July 18, you would get the result of that first and therefore miss the change of that , and count 1000 characters, resulting in 2× expansion and an unjust disqualification.

Rules for evaluating other people's hooks and articles[]

Rules of thumb for preparing updates[]

Users are encouraged to help out by preparing updates in the seven prep areas. Promoting your own articles is generally discouraged, and promoting your own articles before they have been independently verified is not allowed. Updates should be filled from the approved nominations page, including those being held for specific dates in the Special occasion holding area at the top of the page.

Here are a few rules of thumb for preparing updates:


  1. ^ There are other ways to count characters if you don't have prosesize.js installed (although it is fast and easy to install). For example, if you are using Microsoft Word, select the text from the article page (or, in the case of "Did you know" nominations, the DYK talk page) – not the page containing Wikitext – then copy and paste it into a blank document. Click "Tools" ("Review" in Office 2007), then "Word Count", and note the "Characters (with spaces)" figure. Other word-processing programs may have a similar feature. For Mac users, Apple has a Word counter widget available for Mac OS X 10.4 or later.
