One of the patch notes you may or may not have noticed is the one about changing when the weekly raid resets.
So if you did your weekly raid on Tuesday this week just after the reset you may be thinking you can't do it again until next Tuesday. Or if you read the patch notes you might be thinking next Wednesday.
Nope you could actually do the weekly raid on 3 consecutive days this week.
Monday Night - last night of week 1
Tuesday Night - first night of week 2
Wednesday Night - first night of week 3 following patch 3.3.3 shuffle
