2 observances land on 30 October. We have not found a recorded founder for any of them.
| Observance | Declared by | First year | Source |
|---|---|---|---|
| Thevar Jayanthi Thevar community, India | no record | — | — |
| Mischief Night | 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 30 October here. The next one is Saturday, 30 October 2027.
Saturday, 30 October 2027 has no name yet. It costs $2.
