How to disable the past date and the past month using full calendar in select option I tried out with this function in full calendar 

```
select: function(start, end, allDay) {
  var check = $.fullCalendar.moment(start).format('DD-MM-YYYY');
  var today = $.fullCalendar.moment(new Date()).format('DD-MM-YYYY');
  if (check >= today) {

  }
}

```

but not working, it disables next month also. if it possible in javascript? also it fine.[Demo link](http://jsfiddle.net/sedhurabe/x7ts49kd/9/)
