"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 25 September here. The next one is Saturday, 25 September 2027.
Saturday, 25 September 2027 has no name yet. It costs $2.
