easy calculation of weeks of certain period with java
<p>Is there any easy library or approach to get the week (from which date ~ date) of certain periods?</p>

<p>Example:
There is <code>6 weeks(variable)</code> (start from 1 July, 2012 ~ 11 Aug, 2012).</p>

<p>I want to cut off the 6 weeks into <code>2 portions (variable)</code>. So the results will be</p>

<pre><code>1) 1 July,2012 ~ 21 July, 2012

2) 22 July,2012 ~ 11 Aug, 2012... etc
</code></pre>

<p>With jodatime, I can easily get the number of weeks between certain periods though.</p>

<p>All I know is <code>Start Date and End Date</code> which both are variables and <code>cutoffweeks amount</code>(eg.6 weeks or 4 weeks).</p>
