Don't bring up the word date yet. Just ask her if she wants to go out to a movie or something. When it is almost over you'll be able to tell whether she's into you & wants to start dating you.

None. 1st, have a place in mind where you want to take her. Keep it simple! Then, when you approach her, let her know that you would like to visit (that place), and if she would be interested in joining you. Makes it about her, not about you.
