Palm Beach InterNations Monthly Events

Just wondering, are the events always in the middle of the week? I come from the lively Tampa Bay InterNations community where they have the monthly events on the last Friday of the month with a super turnout and people are relaxed with the workweek behind them, ready to dine and meet and greet. Maybe I'm the only one who's not used to going out in the middle of the week but would be all for it at the weekend.
