title: Cron expression with excluding of a specific day of week
body: <p>I want to create cron expression for a my job, but I don't know, how I can excluded specific day of week from expression.</p>
  
  <pre><code>triggerBuilder
         .ForJob(jobKey)
         .WithSchedule(CronScheduleBuilder.CronSchedule("????")).InTimeZone(TimeZoneInfo.Utc))
         .StartNow()
         .WithIdentity(triggerKey)
         .Build();
  </code></pre>
  
  <p>For example: I want to fire my job every day except Monday.</p>
  
  <p>I found approach where we can set firing of job at noon (12 PM) every day from interval:</p>
  
  <p><code>0 0 0 ? * MON-FRI</code> or <code>0 0 0 ? * 1-5</code></p>
  
  <p>but what about excepting specific day from this interval, for example "Thursday".</p>
  
  <p>Thanks for a help :)</p>
