Detect day of week, time of day, and return a statement

I'm trying to set up an embedded system onto my web page. I would like it to detect if it is Saturday or Sunday, and if it is, then find out if it's between the hours of 9 AM central to 5 PM central. If it fits both of those categories, I'd like it to automatically return a statement. If it is any other time, I'd like to return a different statement.

 

Date Object: http://www.w3schools.com/jsref/jsref_obj_date.asp plus "if" statement/ comparisons will do the trick
