According to The Futon Critic, here's the details on the second season schedule:
The season will begin on Thursday, September 6th at 8 PM, and the episode that night will be two hours.
In addition to new episodes at its usual Thursday at 8 PM timeslot, it will air new episodes on Fridays at 8 PM as well for four straight weeks beginning in the second week of the second season.
Personally, I think that "Are You Smarter Than a Fifth Grader?" should move to Fridays at 8 PM. But that's just me.
