title: Get next week's date of a certain day in JavaScript
body: <p>Depending on today's date (new Date()), I would like to get the date of the next Thursday at 7pm in javascript. For example:</p>
  
  <p>If today's date is "Mon Apr 24 2017 13:00:00 GMT" I am looking for the result:</p>
  
  <pre><code>Thu Apr 27 2017 19:00:00 GMT
  </code></pre>
  
  <p>However, if today's date is "Thu Apr 27 2017 21:00:00 GMT" (a Thursday, but past 7pm) I am looking for the result:</p>
  
  <pre><code>Thu May 4 2017 19:00:00 GMT
  </code></pre>
  
  <p>Any help would be much appreciated!</p>
