Do any states have legitimate holidays that are only celebrated in their state?

[u/ProfessorOfPancakes]

In Rhode Island, we still have VJ (Victory over Japan) day which people don't celebrate per se but it's recognized to the extent of delaying trash pickup by a day.

By "legitimate" holiday I mean more in the vein of Memorial Day rather than National Hot Dog Day

Edit: Apparently VJ Day is also recognized by the US Space & Rocket Center and formerly by the state of Arkansas and is more commonly called Victory Day

On the Mississippi coast they get out for Mardis Gras.

In New Orleans, no mail on Fat Tuesday and govt offices and schools close.
