$("#slider2").slider("value",1);
$("#slider2").slider({
    max:41,
    min:1,
     /*
    change:function(event,ui){
        $("input#days").val(ui.value)
    }
    */
    slide: function(event, ui) {   $("#days").val(ui.value) }
});

$("#days").val($("#slider2").slider("value"));

$("#days").change(function(event) {
  var data = $("#days").val();
  if (data.length > 0)
  {
     if (parseInt(data) >= 0 && parseInt(data) <= 41)

        }
     }
  }
  else

If you want to simply add the number of days to the current date, you could use a function like this:

function addDaysToDate(days) {
  var d = new Date();
  d.setHours(d.getHours() + (24 * days));
  return d;
}

You would just pass in the numeric days argument (which in the example would be the value from #days) and you would get back a date that many days in the future.
