"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 5 June here. The next one is Saturday, 5 June 2027.
Saturday, 5 June 2027 has no name yet. It costs $2.
