Currently dates are displayed in American style (month, day, year), on both the form and the output produced by the form. There should be a way for administrators to set the format for dates - at the very least, whether month goes before the day, or vice versa. Maybe the best solution is to use the value of the $wgAmericanDates variable, which is already an optional setting in the main MediaWiki LocalSettings.php file.
