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.
Er that's undoable. I usually don't get home on sundays till say midnight-1am your time due to church or whatnot. I can almost consider doing like 10-11pm your time on sat if there's no other option
if for some reason you can make it earlier then 9pm my time on sunday im fine with it, but otherwise i would prefer playing around 10-11pm my time on Saturday, although Sunday night around 12/12:30am my time isnt undoable
