Format Concatenated Date field

[geospatial]

I am trying to create a report where it creates student certificates for completion of a course. The issue I have is formatting the date of the courses. In the course table I have 2 columns (start and end date) They are in format mm/dd/yyyy. On our current certificates the date format is 10 - 21 July 2017 if the dates are in the same month and 21 July - 15 August 2017 if the dates fall in different months. How can I take the dates I have and format it as stated?

Thanks,

Got it working. Almost done with my report and getting excited. Im going to be able to use part of the code you originally gave me to help in other areas of the form so thanks again.
