Change Date Format in Event

This is a great application!

I am trying to change the format in which the date is displayed in the Events lists. I need it to be in any of the following formats:
12/31/07 = mm/dd/yy
Dec 31, 2007 = Mmm dd, yyyy
Monday Dec 31, 2007 = Ddd Mmm dd, yyyy

Whats the latest on a Calendar View option?
