title: Convert Days in Year, Month, Day datetime format
body: <p>i studying TDateTime functions and procedure, but not found something that allow me to convert a number of days in equivalent Year, Month, Day, for example, if i have days = 0 i should to have as result:</p>
  
  <pre><code>Year:   0
  Month:  0
  Day:    0
  </code></pre>
  
  <p>or i have days = 1, should have:</p>
  
  <pre><code>Year:   0
  Month:  0
  Day:    1   // Just 1 day 
  </code></pre>
  
  <p>or if i have days = 32:</p>
  
  <pre><code>Year:   0
  Month:  1  // January is 31 days
  Day:    1  // Day is 1 
             // Total are 32 days 
  </code></pre>
  
  <p>etc, considering too when february month is of 29 days and not only 28. 
  In delphi xe2, who can tell me what function do it, or if need write it manually? Thanks very much.</p>
