I have a document in Word 2010 that I need users to complete the date in the format d day of MMMM, yyyy ideally using the Date Picker Content Control. I'd also like the day to have a superscripted ordinal. For example when a user chooses the date July 7, 2017 from the Date Picker Content Control the result is displayed:

7th day of July, 2017

Currently I have a Date Picker Content Control titled PerformDate formatted to MMMM, yyyy and a field linked to it with the ordinal switch. This gets me the day with the ordinal, but I still have to manual update the field each time the Date Picker Content Control is updated and I don't know how to automatically superscript the ordinal.

I'm pretty sure that this is not the best approach, but I'm kind of stuck at this point. Any suggestion on code to complete the method I've got going or any ideas of different approaches?
