I have a form that I am updating the labels based on a date entered at the beginning of the form.

When the form is submitted, the date labels display correctly.

It is only when the user either downloads the form after submission or the form is saved to Laserfiche that the date labels display 2 months and 21 days off.

For instance, the date labels when the form is submitted is "09/09 Saturday". When the form is downloaded, the date label displays "11/30 Wednesday". The day of the week is incorrect as well. It should read "11/30 Thursday".

When I hard-code the parse_date (EX: parse_date = new Date (2017,8,9), the form will display in forms correctly and also download correctly displaying the correct lables.  

Please see javascript below: 

function datelabels(){
	
	//Initialize Variables
    var str_date, parse_date;
    var arr_date = new Array (), arr_labels = new Array ();
  
    //Assign str_date
    str_date = $('.payperiod div[type="text"]').text();
    if(str_date === ''){ str_date = $('.payperiod input').val(); }

    
    
    //BEGIN PROCESS - If Empty
    if(str_date !== ''){
    	//Get Year, Month, and Day
      	arr_date = str_date.split('/');

     		
        //Build Labels List for All Tables
      	for(var i = 13; i > -1; i--){
            
      		parse_date = new Date(parseInt(arr_date[2]), parseInt(arr_date[0]) - 1, parseInt(arr_date[1]));
      		parse_date.setDate(parse_date.getDate() - i);
      		str_date = addZero(parse_date.getMonth(), 'm') + '/' + addZero(parse_date.getDate(),'d') + ' ' +  getDayString(parse_date.getDay());
                                                                       
          //str_date = addZero(parse_date.getMonth(), 'm') + '/' + addZero(parse_date.getDate(), 'd') + ' ' + getDayString(parse_date.getDay());
          
            arr_labels.push(str_date);
            
    	} //END OF FOR LOOP
      	
        
        i = 0;//Counter For Retrieve Dates From Array
      	
      	//IF COLUMN NAMES CHANGE, UPDATE THIS CODE!!!!
	    $('.wlabels tr th label').each(function(){
          if($(this).html() !== 'Payroll Use'){
            if($(this).html() !== 'Total'){
              $(this).html(arr_labels[i]);
              i++;
            } else { i = 0; }
