3 observances land on 18 January. We have not found a recorded founder for any of them.

| National Thesaurus Day United States | no record | — | National Day Calendar |
| National Winnie the Pooh Day United States | no record | — | National Day Calendar |
"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 January here. The next one is Monday, 18 January 2027.
Monday, 18 January 2027 has no name yet. It costs $2.
