title: django: datediff sql queries?
body: <p>I'm trying to do the equivalent of the following SQL in Django:</p>
  <pre class="lang-sql prettyprint-override"><code>SELECT * FROM applicant WHERE date_out - date_in &gt;= 1 AND date_out - date_in &lt;= 6
  </code></pre>
  <p>I can do this as a RAW sql query, but this is becoming frustrating in dealing with a RawQuerySet instead of a regular QuerySet object as I would like to be able to filter it later in the code.</p>
