Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I'd prefer Thursday of the days mentioned tbh, going to be on a walk sometime later for election and dinner stuff so not sure when I'll get home (could be before 6PM for all I know but don't want to say yes to a time I'm not sure if I'll make). Could also try Wednesday.
