"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 12 November here. The next one is Thursday, 12 November 2026.
Thursday, 12 November 2026 has no name yet. It costs $2.
