title: How to check if a DateTime range is within another 3 month DateTime range
body: <p>Hi I have a Start Date and End Date per record in a db.</p>
  
  <p>I need to check to see where the time period falls in a 2 year period broken into two lots of quarters then display what quarters each record falls into.</p>
  
  <p>Quarter 1 includes June 09, Jul 09, Aug 09<br>
  Quarter 2 includes Sept 09, Oct 09, Nov 09<br>
  Quarter 3 includes Dec 09, Jan 10, Feb 10<br>
  Quarter 4 includes Mar 10, Apr 10, May 10<br>
  Quaretr 5 includes Jun 10, Jul 10...  </p>
  
  <p>e.g. 01/10/09 - 01/06/10 would fall into quarters 2, 3, 4 &amp; 5</p>
  
  <p>I am very new to .NET so any examples would be much appreciated.</p>
