How do I find out if Chiller is offered by Comcast in my area?

The Comcast website is a maze. I wouldn't know where to look. I go through and flick through the channels and I don't see it on there. People have told me that two shows I like Rod Serling's Night Gallery and the Sixth Sense are on Chiller. Not sure if I even have it on all those gazillion channels I have on Comcast. How do I go about finding out?
