3 observances land on 21 August. We have not found a recorded founder for any of them.
| Observance | Declared by | First year | Source |
|---|---|---|---|
| Ninoy Aquino Day Philippines | no record | — | — |
| Youth Day Morocco | no record | — | — |
| World Senior Citizen's 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 21 August here. The next one is Saturday, 21 August 2027.
Saturday, 21 August 2027 has no name yet. It costs $2.
