inshortezza on "[Plugin: Contact Form 7] Date field and calendar language"

I have a form with Date Field + Calendar.
My WordPress is installed in english versione.
My computer is located in Italy.
All site is in english but the field and the calendar is in italian (gg/mm/aaaa). I need to be in english (dd/mm/yyyy).
This is the page http://www.ridgeline.bike/2016nuovaprova/book-now/
How I can do?

Hi,

I tested your form, and your calendar is actually in English.

Can you check it again please? Also, this article might help you Contact Form in Your Language.

Ok.
Then maybe it is the browser language that determines the language of the calendar?
If is it, it's ok.
Thanks
