Monday was a reschedule from Thanksgiving and Wednesday was a reschedule for today. Look at the rest of the tier. All 3 days a week.
We actually weren't gonna be able to raid next week because 2 of our 3 tanks for Garrosh had finals and couldn't raid.

No we didnt add a night because we were close. It was a rescheduled raid day that was established weeks ahead of time. http://imgur.com/Wq1vTkm
We did raid an extra like 30 minutes on Thursday night to get the kill though.
