title: Spring Cron Expression to run every Tuesday night 9?
body: <p>I am using Spring schedule. I configured the following Cron expression to run my task every Tuesday night at 9pm, </p>
  
  <pre><code>"0 0 21 * * TUE"
  </code></pre>
  
  <p>However, I am getting the following exception when am starting the application</p>
  
  <blockquote>
    <p>Encountered invalid @Scheduled method 'runSchduler': Cron expression must consist of 6 fields</p>
  </blockquote>
  
  <p>Is my Spring Cron expression wrong? </p>
