I have a calender that I am sing for an application and a client that requires the date to be displayed differently than the default mm/dd/yyyy - they require the calendar to display the day in this format: Jan 01 2010, Feb 01 2010, Mar 01 2010 and so on.
can someone please direct me on how to change the below JS to accommodate this request? I am lost, especially since the JS below deals with dates.
Thanks, much appreciated!!
