title: Way to query database with SQLAlchemy where a date is a particular day of the week?
body: <p>I have a table (called 'entry') which has a datetime column (called 'access_date'), and I want to do an SQLAlchemy query that only produces results where entry.access_date is a Monday (or any other day of the week specified by a number [0..6]). </p>
  
  <p>Is this possible? I am using sqlite &amp; SQLalchemy 0.5.8 if that makes any difference.</p>
