I have the need to be able to control the visibility of a number of modules within a site based on Date ranges, and would like to automate the process vs manually updating the date range in the module settings. 

I.e. have a module that is visible the FIRST week of every month, another the SECOND week and so on...

Or, have a module that is visible every week except Monday from 9am - 11am.

I don't want to manually have to update module settings each week. 

Is there a way to do this easily? Or a module management tool that might provide a tool set?

Help appreciated. 

Thanks Chad, 

that's a great solution to look into for the main content.

One other question for everyone, I'm looking to setup an event countdown, which I want to stop during a weekly event, then countdown to the next event, which might be later in the week, and to cater to recurring events.  Is the suggestion above going to do that? Or is anyone aware of a countdown module that caters to recurring events?  My searched haven't found anything (other than joomla options)... Be really grateful if someone had some thoughts around how to tackle this (note, I'd like to be able to cater to the possibility of having multiple events on the same day. I'm assuming this could be achieved using multiple instances of a countdown module, then implementing the theme suggestion above, however would prefer to just be able to set this up within the module itself).
