title: Cron format for specific date and time, running once a year only
body: <p>I have to schedule the cron to run at specified time. I have the command like below. But I could not understand how to run only once in a year at a specified date and time. </p>
  
  <p>My question is: what should the value for 5th field (Day of the Week) be?</p>
  
  <pre><code>30 06 02 01 * bash -x /home/user/cron-specified-time.sh
  </code></pre>
  
  <p>Time/date: Jan 2nd 06:30 AM - only once in a year</p>
