I am looking for a script that will dynamically change the content of a page on a weekly basis.

I have a navigation bar that changes on a weekly basis
because its following a calendar of events. (And no... It's not my main one or else that would be designer suicide) So..... my intent is to load up the information once a month and then have the page change once a week with the updated links.

Those updated links point to another html page that has the entire listing of events for the month and each event has an internal link that the navigation points to.

To see what I mean... go to www.calvarywl.com and look at the top portion of the right hand navigation bar where it says "up coming events". It's that right hand navigation bar that will change the events listed.

Any help would be great.

Thanks
