This is something that really confuses me, because girls don't know if this is just casual or an actual date if I just say "do you want to go and have lunch this Thursday?" They may think this is just like hanging out, nothing else. While if I actually tell her "Do you want to go on a date with me? How about having lunch on Thursday". But at the same time you don't to come to forward, desperate or whatever, you know how it is...and actually saying "do you want to go out on a date" seems sterile to me.
