As the title describes so far I have found the best way to close and ensure a day two, is to arrange the date when you meet her provided an insta date isnt an option. You dont have to go into specifics but place and rough time (atleast what day) are enough, and I have found this method particularly effective compared to number closing and planning a date via calling or texting. On a side note I have also found it very useful to tell the girl when you ask for her number (number close ) that she should only give you her number if she is actually interested in going on a date, it puts them on the spot to make the decision and makes her commit alot more to the plans.
