Have a nice holidays (holidays as a plural noun or singular)??
or have nice holidays ?

it seems terribly confusing to me

'Have a nice holiday' is the commonly used expression. Grammatically, it's either 'a holiday' (singular) or 'holidays' (plural). The indefinite article can only be used with singular count nouns.

[Prezbucky]

In the United States, a holiday is a specific date on the calendar (EG Christmas Day, Easter, Halloween, etc.).

Some offices/companies also refer to personal days off as "personal holidays" or some such term.

When we go somewhere to have fun, we call it a vacation.

Tom: Are you going on vacation this summer?
Jamie: Yes, we're going to spend two weeks in Miami.

Tom: What are you doing for the Martin Luther King holiday?
Jamie: I think I'll stay home and catch up on sleep.
