2 observances land on 13 November. We have not found a recorded founder for any of them.
| Observance | Declared by | First year | Source |
|---|---|---|---|
| Sadie Hawkins Day United States | no record | — | — |
| World Kindness Day | no record | — | — |
"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 13 November here. The next one is Friday, 13 November 2026.
Friday, 13 November 2026 has no name yet. It costs $2.
