title: Pass today's date as argument for a cron job
body: <p>I have a cronjob that will be launched at the end of each month to generate a monthly report.</p>
  
  <p>Here I found how to launch the job at the end of each month:
   <a href="https://stackoverflow.com/questions/6139189/cron-job-to-run-on-the-last-day-of-the-month">Cron job to run on the last day of the month</a></p>
  
  <p>Now, I just want the date of the last day of the month as an argument for the script.</p>
  
  <p>For example:</p>
  
  <pre><code>compute_monthly_rate -e **2016.01.31**
  </code></pre>
  
  <p>How can I pass this date as an argument?</p>
