Invalid date pickup for locale date format

If language local date format has different order like standard
"English", then selection in popup calendar get invalid date. For
example, Czech or Slovak date format start with day number (dd.MM.yy).
If date format not start with month number, then new Date() parse
invalid date or if day number is not bigger then 12, switch day and
month
