this link will take you to a site where you can type in your show and it will tell you the time and day to find it.
so enter the show name (i.e. fons & porter) in the search window that they provide and watch the day and time come up.
you may have to register. it's free. you tell them your zip code i think, and the info you get is for your area. try it.
