title: getMonth() in Date shows wrong value
body: <p>I am trying to get the month of the given date as a string in javaScript but I get the wrong month of the date displayed.</p>
  <pre><code>var d = new Date(&quot;Sun Dec 13 2020 08:00:00 GMT+0530&quot;);
  console.log(d.getMonth());
  </code></pre>
  <p>I get in the console output for month as 11 for some reason.</p>
