I've got 2 dates lined up this week. This is the first time I've been successful actually getting a date (in my life)

Questions:

A. How many days in advance should you plan out the date? For example, you match on a Saturday and plan the date on a weekday the following week. How many days in between should there be, does this matter?

B. How much texting/communication should there be in between the match and the date? I have both of their phone numbers and haven't texted them yet, but got their numbers through snapchat and that's where the majority of the conversation took place. Should I send them a text message a day before the date to confirm things, or just the day of?

C. Are weekdays or weekends generally better if both people are free? I would imagine weekends right?

Thanks for any info, and sorry for my complete lack of knowledge on this matter.
