The Attributes Plugin allows to specify the date field. But the locale in this field is English. The same with a popup window for required fields after pressing the send button -- it says Please fill out this field. I checked the plugin code, but I was unable to find anything that would allow to translate either the date field, or the required field popup message. Any idea how to translate it?

It looks like this plugin reads the system/browser locales and displays the calendar in that language.

No plugin does not do that, isn't that HTML5 calendar?

I don't know, but it depends on the system/browser locale. When I tested it with my Android phone, it changed the names based on what system language I've chosen. So the calendar was in Polish if Polish language was set. The same with English.

Yes that's html5

Ok, it's nice.
