4 observances land on 14 September. We have not found a recorded founder for any of them.
| Observance | Declared by | First year | Source |

| Hindi Day Hindi-speaking states of India | no record | — | — |
| Mobilized Servicemen Day Ukraine | 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 14 September here. The next one is Tuesday, 14 September 2027.
Tuesday, 14 September 2027 has no name yet. It costs $2.
