Calendar Check out date = check in date +1day

I use contact form 7.

I have a check-in-date and a check-out-date field.
When a user selects the check-in-date, then when he clicks the check-out-date it should show automatically on the calendar the “check in date plus 1 day”.
What i want is similar to all the booking calendar forms we see out there.

I us this code:
CheckIn
[date* Salida-157 min:today max:2022-12-31 step:1 class:required “2021-03-04”]
CheckOut
[date* Salida-158 min:today max:2022-12-31 step:1 class:required “2021-03-05”]

I found this code but I dont really know if it works:

jQuery(function($){
    $("#date1").datepicker({
        dateFormat: 'dd/mm/yy',
        onSelect    : function (selected) {
            var unique = $(this).attr('id');
            unique = unique.replace('date1', '');
            var date = $(this).datepicker('getDate');
            if (date) {
                date.setDate(date.getDate() + 1);
            }
            $( '#date2' + unique).datepicker( 'option', 'minDate', date)
        }
    });
});

Best Regards
