3 observances land on 30 May. We have not found a recorded founder for any of them.
| Observance | Declared by | First year | Source |
|---|---|---|---|
| Canary Islands Day Spain | no record | — | — |
| Indian Arrival Day Trinidad and Tobago | no record | — | — |
| Mother's Day Nicaragua | 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 May here. The next one is Sunday, 30 May 2027.
Sunday, 30 May 2027 has no name yet. It costs $2.
