3 observances land on 4 April. We have not found a recorded founder for any of them.
| Observance | Declared by | First year | Source |
|---|---|---|---|
| Children's Day Hong Kong, Taiwan | no record | — | — |
| Peace Day Angola | no record | — | — |
| NATO 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 4 April here. The next one is Sunday, 4 April 2027.
Sunday, 4 April 2027 has no name yet. It costs $2.
