title: Get every Friday, Saturday and Sunday in a given time frame
body: <p>What is an easy way to get every Friday, Saturday and Sunday betwee two dates, without using the datetime object of PHP5.0.</p>
  
  <p>Because of the speed I don't want to traverse every date between 1/1 and 31/12. (per page I have to calculate it at least 50 times :) as part of a result view.)</p>
