There is no settings available directly in Contact Form 7 that allows you to change the language of a date picker. It can be done via custom programing but you would need to be rather skilled at WordPress development using and jQuery codding.

Hi,
with the following code in the header.php of the theme, the date picker is in french.
<script type=”text/javascript”
src=”http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/i18n/jquery.ui.datepicker-fr.js”>
</script>
But now the date is in english format.
Someon know how to have the in french format (jj/dd/yyyy or jj-dd-yyyy)
Thanks
In footer.php, before </body> add following code:
<script type="text/javascript">
var $ = jQuery;
jQuery(document).ready(function() {
var $ = jQuery;
$(this).find('input.wpcf7-date[type="date"]').each(function() {
$(this).datepicker( "option", "dateFormat", "dd/mm/yy" );
});
});
</script>
Unfortunately contact form 7 wrong date validation, so I’ve removed it by the addition of this row in functions.php:
remove_filter( 'wpcf7_validate_date', 'wpcf7_date_validation_filter', 10, 2 );
remove_filter( 'wpcf7_validate_date*', 'wpcf7_date_validation_filter', 10, 2 );
