Wikipedia:Did you know/Statistics/Monthly DYK pageview leaders/Rules

This section details the most-viewed DYKs, by month, from the beginning of the available data – December 2007. Unfortunately, the articles that appeared in the DYK section before that date do not have page view information and cannot be included.

Rules

 * 1) Use ErrantX's DYKStats tool which will calculate the statistics for you based upon the date and time it was featured on the Main Page. You can use Recent additions to find out whether it was posted during AM or PM (UTC); remembering that recent additions lists the time it was removed from the Main Page.
 * Historical (pre-2016) statistics are based on Henrik's page view tool at http://stats.grok.se/. For more information on this tool, see http://stats.grok.se/about and stats FAQ. Please note that at some point since December 2013 this tool began compiling days using a 23:00 to 22:59 (UTC) time range to match the range that wikiviewstats uses rather than the 00:00 to 23:59 (UTC) time range that it had previously used. Also, note that these statistics ignore mobile viewers. For queries, go to Henrik's talk page – missing stats are often the result of the tool being down or missing source files. Normally, you should count page views only for the day X when the article was featured. Because of the timing of the stats collection, nearly all hooks which exit the main page around 00:00 UTC get extra DYK views on the next day X+1; in this case views for two consecutive days (X and X+1) should be summed.
 * 1) The views are counted and summed for all articles which were bolded (not merely linked) in the hook. If one or more bolded articles were moved while on the main page, add views for the main article(s) and the redirect page(s).
 * 2) This page aims to list the views originating from the DYK section of the main page. Some articles draw additional views unrelated to DYK. Those views are removed by subtracting a half sum on the days before and after, that is VX &minus; (VX&minus;1 + VX+1) / 2. Example VX=18,400; VX&minus;1=4,400; VX+1=2,000; total=18,400&minus;(4,400+2,000)/2=15,200. Other "special occasion" hooks may draw additional views because of the occasion, not because of the DYK; these cannot be accounted for with this method. For example, the hook for Tom Moore scheduled on his 100th birthday may have attracted extra views because of the celebration activities on that day which are not directly related to DYK, a factor this listing does not consider.
 * 3) Subject to rule 3, any article receiving at least 416 $2⁄3$ views per hour (after subtracting background views) is eligible for listing on the "STATS" page. If you know of an article that has received more than 416 $2⁄3$ views per hour while on DYK, feel free to add it to the list.
 * 4) Anyone is free to help by checking page views and listing hooks here that meet the requirements. Help is also welcome reviewing page views for earlier months where data is waiting to be mined (Jan–May 2008).
