Time dependant content within a resource

Is there any way to have some content in a resource to only show within a certain time window? I’m using Evolution.

For instance. I have a resource which is a TV show. And I want to show the Episode description on the day of the episode only. Then the day of the next episode will show the information for that episode.
I had planned to have each episode as child-resources, but my client wants to do it this way.

Any ideas guys?

Cheers,
Adrian.

Sample post below
-------------------------------------
TV Show Name
blah blah blah

Episode Title [01.01.2011]
blah blah this is viewable

Episode Title [03.01.2011]
blah blah this is not viewable
-------------------------------------

I would still have each episode as a child resource with publish/unpublish dates as appropriate, using Ditto on the parent page to display the episode since Ditto will only display published resources.
