This is the attitude: "I am doing this and I think you would have a fun time with me if you came along." Man "Woman, I have two tickets to the amazing concert Friday night. Would you like to join me?"
I also strongly suggest not telling her all the times you are free.
If she is busy, it is her turn to offer a date she is free.
