<p>But I am unable to disable the past dates. I tried the following; according to <a href="https://github.com/uxsolutions/bootstrap-datepicker/issues/438" rel="nofollow noreferrer">an issue</a> in GitHub, but it didn't work for me.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>$(document).ready(function() {
  var date_input = $('input[name="date"]'); //our date input has the name "date"
  var container = $('.bootstrap-iso form').length &gt; 0 ? $('.bootstrap-iso form').parent() : "body";
  date_input.datepicker({
    format: 'mm/dd/yyyy',
    container: container,
    todayHighlight: true,
    autoclose: true,
  })
})
$(function() {
  var nowDate = new Date();
  var today = new Date(nowDate.getFullYear(), nowDate.getMonth(),
    nowDate.getDate(), 0, 0, 0, 0);
  $('#date').datepicker({
    startDate: today
  });
})</code></pre>
