"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 18 June here. The next one is Friday, 18 June 2027.
Friday, 18 June 2027 has no name yet. It costs $2.
