disable past dates on datepicker

Question

How to disable past dates from the current date on a datetimepicker? I tried few posts for similar question but was unable to achieve it, Below is what I tried

<link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.2.2/css/bootstrap-combined.min.css" rel="stylesheet"> <link rel="stylesheet" type="text/css" media="screen"  href="http://tarruda.github.com/bootstrap-datetimepicker/assets/css/bootstrap-datetimepicker.min.css"> <script type="text/javascript"  src="http://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.3/jquery.min.js"> </script>  <script type="text/javascript"  src="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.2.2/js/bootstrap.min.js"> </script> <script type="text/javascript"  src="http://tarruda.github.com/bootstrap-datetimepicker/assets/js/bootstrap-datetimepicker.min.js"> </script> <script type="text/javascript"  src="http://tarruda.github.com/bootstrap-datetimepicker/assets/js/bootstrap-datetimepicker.pt-BR.js"> </script> <script type="text/javascript"> $(function() {   $('#datetimepicker2').datetimepicker({     language: 'en',     pick12HourFormat: true   }); }); </script>  <div id="datetimepicker2" class="input-append"> <input data-format="MM/dd/yyyy" type="text"/> <span class="add-on">   <i  data-date-icon="icon-calendar">   </i> </span> 

I also tried

$("datetimepicker2").datepicker({ changeYear: true, dateFormat: 'dd/mm/yy', showOn: 'none', showButtonPanel: true,  minDate:'0d' });  

and

$("#datetimepicker2").datepicker({ minDate: 0 }); 

Answer 1

Give zero to mindate and it'll disabale past dates.

$( "#datepicker" ).datepicker({ minDate: 0});
