title: Calculating sunrise and sunset with java
body: <p>I search a way to calculate sunrise and -set for a given timezone aka location. I would like something similar to <a href="http://framework.zend.com/manual/en/zend.date.overview.html#zend.date.other.sun" rel="noreferrer">Zend_Date</a>.</p>
  
  <p>The idea is to have an application where you can select a location and based on that you get the actual time and also sunrise, -set time.</p>
  
  <p>Cheers and thanks,<br />
