This idea would work well for community events that list dozens of activities during a day or two where expired events would go away based on end time. This would also work for other reasons such as Shipping Deadlines (with the current feature of "Display recurrent events only once") and places that wish to display Hours of Operation that change when closed, etc. plus we could personalize days of week (i.e. "TGIF") or specials (i.e. "Hump Day Savings") and things like Closed for Columbus Day for some reason way in advance.
