Disable discount if delivery date

Question

I added one discount method using Shopping Cart Price Rules. It is active for 13th June 2014 to 25th June 2014.

But now I have to disable the price rule as per the below.

That mean

1. If the order has placed on 15th of June and Delivery falls on 28th , then there is no discount.
2. If the order has paced on 15th of June and Delivery falls before 26th, then discount is there.

How to do this with admin panel? Or am I need to do any coding?
