Crontab quartz schedule
<p>I want to setup a crontab expression that will start a job at every 20 mins and it will run following the time table</p>

<p>7-30am to 8pm Monday-Friday and 7-30am to 4pm Saturday</p>

<p>So far I have the following,</p>

<p><code>0 30 7 ? * MON-FRI Fire at 7:30am every Monday, Tuesday, Wednesday, Thursday and Friday</code></p>

<p>So far I have the following,</p>

<pre><code>&lt;schedule&gt;
    &lt;job&gt;
        &lt;name&gt;job1&lt;/name&gt;
        &lt;job-class&gt;class&lt;/job-class&gt;
    &lt;/job&gt;
    &lt;trigger&gt;
        &lt;cron&gt;
            &lt;name&gt;AtoZ&lt;/name&gt;
            &lt;job-name&gt;AtoZ&lt;/job-name&gt; 
            &lt;cron-expression&gt;0 30 7 ? * MON-FRI&lt;/cron-expression&gt;
        &lt;/cron&gt;
    &lt;/trigger&gt;
&lt;/schedule&gt;
</code></pre>

<p>I will really appreciate if someone can help me with this.
Thanks in advance.</p>
