The events, births, deaths and observances above are from the English Wikipedia article “October 3” and the articles it links to (authors and history), retrieved 2026-10-15 through the Wikimedia “On this day” feed. They are licensed under CC BY-SA 4.0; this selection is shared under the same licence. Every anniversary that Wikipedia's editors selected for October 3 stays on the list; the remaining places, up to 27 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. The 1990 entry stays as well, and comes first in the one-line summary: we keep a short list, checked by hand, of widely known events that Wikipedia's editors leave out of their selection, usually because the article carries a maintenance notice. Each list runs by year, and the wording is unchanged apart from removing references to pictures, audio and video.
