The correspondent lines from dateMenu.js:

        /* Translators: This is the date format to use when the calendar popup is
         * shown - it is shown just below the time in the shell (e.g. "Tue 9:29 AM").
         */
        dateFormat = _("%A %B %e, %Y");
        this._date.set_text(displayDate.toLocaleFormat(dateFormat)); 


I have some more Hebrew bugs to report but I won't be able to do so until I'll have the ability to make this locale work.

Kind regards,
