Asking someone for a date

Asking someone for a date
Are you free Saturday evening?
Are you free Saturday night?
 Are you busy on the 15th?
What are you up to this weekend?
 What are you doing next weekend?
 Would you like to go to dinner?
Would you like to go out to dinner with me?
 I was wondering if you’d like to go out.
I was wondering if you’d like to see a movie.
If you’re not  doing anything, would you like to go to a party with me?
If you don’t have other plans, would you like to go dancing?
