I know as much (or little) as you do.
However, in addition to the occasional Fri/Sat clashes, a few clashes ago they started it at 3 PM (US Eastern) instead of the normal 3 AM. They were doing maintenance that night so it might have been a one time exception, but I would check mid-afternoon today.
I should also note that the countdown clock they sometimes to note an impending club clash is not running yet, so I'm inclined to think it will be Fri/Sat.
Tom.
