3 observances land on 11 May. We have not found a recorded founder for any of them.
| Observance | Declared by | First year | Source |
|---|---|---|---|
| National Foam Rolling Day United States | no record | — | National Day Calendar |
| National Twilight Zone Day United States | no record | — | National Day Calendar |
| National Eat What You Want 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 11 May here. The next one is Tuesday, 11 May 2027.
Tuesday, 11 May 2027 has no name yet. It costs $2.
