"No record" means we could not find one, not that none exists. Where a founder is named, the source is named with it.
Who decides these? Nobody official. A brand, a trade body, a government, or one person with a website. Most are simply asserted and then repeated until they look official. Here, whoever names it first.
Nobody has ever named 4 October here. The next one is Monday, 4 October 2027.
Monday, 4 October 2027 has no name yet. It costs $2.
