I am using the wordpress contact form and its field date picker, its default is DD/MM/YYYY, but I want to change its format to MM/DD/YYYY.

Can any one tell me how to do it in contact form 7.

Copy and paste it in your function file and also you can modify the date format as per requirement.

 add_filter('avf_datepicker_dateformat', 'avf_change_datepicker_format');
    function avf_change_datepicker_format($date_format) {
        $date_format = 'mm / dd / yy';
        return $date_format;
    }

If above writen code is not working its means: If a value is specified in a date field, the value must be in YYYY-MM-DD format (e.g. 2013-04-08) according to the HTML5 specification.

This is in most cases you don’t need to care about because browser’s date picker UI will set a value in the correct format.

I changed the display date format to mm/dd/yy in the front end of my form by using plugin Custom Datepicker NMR for Contact Form 7.

This allows you to use a new input field in your contact form called [datepicker ]

Install/activate the plugin and specify format date to show in the web browser like this:

[datepicker myFirstDatepicker id:myFirstDatepicker format:mm/dd/yy]

This plugin uses jquery-ui datepicker.
