title: SQL to Determine if Current Week is Week Containing N Friday of Month
body: <p>I am looking for some SQL to determine if the current week is the week that contains the Nth Day of the month.</p>
  
  <p>Example.  I want to know if I am in the week that contains the third Friday that will occur this month.  Or which week of the month contains the third Friday.  Weeks should be defined as starting on a Sunday and ending on a Saturday.  So a month that starts on a Saturday would not see it's Friday until the 4th week, where as a month that starts Sunday - Friday, would see it's 3rd Friday in the 3rd week of the month.</p>
  
  <p>Not sure if PL/SQL is required for this or not.</p>
