title: How to add number of days to a date, consider only business days (i.e. ignore weekends)?
body: <p>I'm trying to create a formula to calculate the <em>n-th</em> <strong>Business Date</strong> (only Monday to Friday are business days).
  For simplicity's sake, holidays are not important; only weekends should be ignored.</p>
  
  <p>For example:</p>
  
  <pre><code>   +------------------------------------------------------------------
     |   A                B                     C
     +------------------------------------------------------------------
  1  |  Starting Date    Business-Day Number   Business Date
  2  |  06-Jun-2012      0                     06-Jun-2012
  3  |  06-Jun-2012      1                     07-Jun-2012
  4  |  06-Jun-2012      2                     08-Jun-2012
  5  |  06-Jun-2012      3                     11-Jun-2012    &lt;-- June 9th (Sat) and 10th (Sun) are skipped
  6  |  06-Jun-2012      4                     12-Jun-2012
  ...
  </code></pre>
  
  <p>The formula would be used to fill <strong>Column C</strong> above.
  The only solution I could come up with involves vlookup on a table of working days, which I found a bit cumbersome.</p>
  
  <p>Any ideas how I could go for it in a single formula?</p>
  
  <p>(it can be on Excel or OpenOffice-Calc)</p>
