"Θέλω μία ημερομηνία."

[Jezza54195]

Does the meaning include a date in the American slang sense of an assignation, please?

[D_..]

No, ημερομηνία is just a calendar date.

[S.Eleni]

I believe date, as in a meeting, appointment or to go out with romantically, would be ραντεβού or βγαίνω depending on the context.

Soooo what does this mean then?

[D_..]

I take it to mean 'Give me a number, is it going to be in December, in May, on the 2nd, on the 15th, this year or the next?' Someone is trying to arrange a date for an event.

Or maybe your boss asking you when some work will be done?

[Charaxan]

It means that if you tell me "can we meet ?" I can anwer you "all right i want a date" or "all right give me a day we can meet".
