Correct date format for challenge submissions.
May 21, 2013

I have tried every combination I can think of to have my challenge submission accepted, but still receive the message "invalid date"  Please provide the correct submission format for Monday, May 19, 2013 as a sample from which I can work.  Many thanks.
