You can make a Date field unique .but not in the direct way. It like a simple work around.where you need to create a text field ,make it as unique and update this field with the date value through workflow .By using formula like TEXT(Ur_date__c). This will restrict user from creating duplicate records.Make the workflow to fire every time when ever a record is created or edited.
I dont think so, but you can write a apex trigger to avoid creating a duplicate record for same date value.
