Every anniversary that Wikipedia's editors selected for June 27 stays on the list; the remaining places, up to 26 events, 22 births and 14 deaths, go to the entries whose own article — about the event itself, or else the person or thing it is about — appears in the most language editions (counted from Wikidata); an article about a person or thing, which covers far more than one day, counts half. An entry with no article of its own counts, also at half, by the least covered article it links, and one that links only places counts for nothing. Each list runs by year, and the wording is unchanged apart from removing references to pictures, audio and video.
