In Chicago Jeopardy is 3:30 and Wheel at 6:30. In the Bay Area (last place I actually had access to a television) Jeopardy is at 7 immediately followed by Wheel at 7:30.
Tbh, though, I definitely prefer having Wheel air first myself: it gets me into game-show mode for the clearly superior Chad that is Jeopardy!, whereas doing Wheel after already experiencing J!'s euphoria is just miserable.
The solution to this is to watch Jeopardy and then switch channels or turn off the TV; I have never understood the appeal of watching
Wheel of Fortune to begin with.
