title: Will crontab hour range a-b run after b too?
body: <p>Say I have a crontab which runs every <code>20</code> minutes and I have a hour range which can vary so lets say <code>a-b</code>, which in one example could look like</p>
  
  <pre><code>*/20 5-23 * * * /usr/bin/cool_program
  </code></pre>
  
  <p>My question is, will the cron run at 23:00, 23:20, 23:40 and 00:00 too?</p>
