title: Select between two dates with Django
body: <p>I am looking to make a query that selects between dates with Django.</p>
  
  <p>I know how to do this with raw SQL pretty easily, but how could this be achieved using the Django ORM?</p>
  
  <p>This is where I want to add the between dates of 30 days in my query:</p>
  
  <pre><code>start_date = datetime.datetime.now() + datetime.timedelta(-30)
  context[self.varname] = self.model._default_manager.filter(
      current_issue__isnull=True
      ).live().order_by('-created_at')
  </code></pre>
