title: run every monday at 5am
body: <p>I generated a cron to run every Monday at 5am.</p>
  
  <pre><code>0   5   1   *   1
  </code></pre>
  
  <p>The third number, 1, for day of month, has it set to run on the first of every month as well as Monday.</p>
  
  <p>Do I change that 1 to 0 so it ignores the day of month? Otherwise it will run every Monday as well as run on the 1st of the month.</p>
