it also depends what you want with the girl and what the girl wants with you. i mean if its just to bang, of course night dates are better. but if you just want to get to know a girl, any time of the day is fine cause you just need to communicate and talk, get to know each other. i find that no matter what, talking is what makes both of you chill out. getting to know them more is what you want. if you click with a girl i dont think it matters what time of the day it is. but thats just me.
