Maybe you want something like this?.

$(function () {
    $("#txtFrom").datepicker({      
       onSelect: function(selectedDate) {
            //$("#cal4").datepicker("setDate", selectedDate);
            var date = $(this).datepicker("getDate"); 
            date.setDate(date.getDate() + 15);
            $("#txtTo").datepicker("setDate", date);
            $("#txtTo").datepicker("option", "minDate", selectedDate);
            $("#txtTo").datepicker("option", "maxDate", date);
        }
    });
    
    
  $("#txtTo").datepicker({
   changeMonth: true,
   changeYear: true
  })  
    
});

You should use moment.js for any complicated enough date related javascript task
