title: Schedule a cron job for execution every hour on certain days on App Engine
body: <p>I would like to schedule a cron task to run every hour, but only from Thursday through Monday.  Is a schedule like this possible?  From <a href="http://code.google.com/appengine/docs/python/config/cron.html#The_Schedule_Format" rel="nofollow noreferrer">the documentation</a>, it looks like I can schedule a cron task to run at an hourly interval <strong><em>or</em></strong> on specific days at a single specific time, but I cannot figure out how to schedule a cron task to run at an hourly interval <em>only</em> on specific days.</p>
  
  <p>I've tried schedules like the following in <code>cron.yaml</code>:</p>
  
  <ul>
  <li><code>every 1 hours thu,fri,sat,sun,mon</code></li>
  <li><code>every 1 hours of thu,fri,sat,sun,mon</code></li>
  </ul>
  
  <p>The way I read the documentation, I think this may be impossible.  I'm hoping that I've either missed something or that there is some undocumented syntax for what I'm trying to accomplish.</p>
