Two people getting together for an activity when the possibility of romance between them has been broached but not ruled out. Since the exploration of romance is the purpose of a date, merely asking someone out on a date is sufficient to broach the subject. Dates may or not continue once a couple have entered into a romantic relationship. The word "date" may be used to identify a get together between two people not romantically involved, but this usage is meant to convey irony, since such a meeting is not a date in the true sense of the word.
Yeah, Mike and I went on a date last night. He's cute, but I'm not sure if I want to get involved with him or not.
