Changing date picker language from English to French in Adobe Form

Hi, 

I've created a form in Adobe and I am looking for help to switch the language of the date picker calendar from English to French. 

Currently the calendar is displaied in English and the format I use is ex: Tuesday, June 28. I would like the calendar to be displayed in French and the date format to read: Mardi, 28 juin. 

Thanks,
