I have a WordPress form on my client's hotel website with an arrival field and a departure field.  The client wants the departure date to add +1 day to the minDate when a user selects the arrival date. I have tried adding +1 to several areas but nothing seems to work. I have attached the script I am using (it's using jQuery instead of $ because the form is in a code block in WordPress). I have searched several forums and Google searches with no success.

2. <script>
3.   jQuery(function() { var dateFormat = "M dd,yy", 
4.       from = jQuery( ".check-in-date-view" ) 
5.         .datepicker({ 
6.         minDate: 0, 
7.         maxDate: "+12m", 
8.           defaultDate: "+1w",
9.           dateFormat: "M dd,yy",
10.           altFormat: "mm/dd/yy", 
11.           altField: ".arrival-date",
12.           changeMonth: true, 
13.           changeYear: true, 
14.           numberOfMonths: 1 
15.         }) 
16.         .on( "change", function() { 
17.           to.datepicker( "option", "minDate", getDate( this ) ); 
18.         }), 
19.       to = jQuery( ".check-out-date-view" ).datepicker({ 
20.         defaultDate: "+1w", 
21.         minDate: 1, 
22.         maxDate: "+12m", 
23.           dateFormat: "M dd,yy",
24.         changeMonth: true,
25.           altFormat: "mm/dd/yy", 
26.           altField: ".departure-date", 
27.         changeYear: true, 
28.         numberOfMonths: 1 
29.       }) 
30.       .on( "change", function() { 
31.         from.datepicker( "option", "maxDate", getDate( this ) ); 
32.       }); 
33.  jQuery(".check-in-date-view").datepicker("setDate", new Date());     
34.          jQuery(".check-out-date-view").datepicker("setDate", 1); 
35.     function getDate( element ) { 
36.       var date; 
37.       try { 
38.         date = jQuery.datepicker.parseDate( dateFormat, element.value ); 
39.       } catch( error ) { 
40.         date = null; 
41.       } 
42.       return date; 
43.     } 
44.   } ); 
45. jQuery(".promo-trigger").click(function(){
46.     jQuery(".flyout-wrapper").toggle();
47. });
48. </script>
