Scheduling Page Updates

Is there a way I can schedule various updates to various pages?

For example content on a /contest page for when weekly contests are open that then switches when it closes at midnight

and

content at /event that can be scheduled to change from a "Check back at this date and time" to the event announcement at the aforementioned date and time. 

Did you ever get an answer for this??

I have the same question here and haven't found an answer. Following this feed.
