title: Constraints on Dijit DateTextBox [Valid days of the week]
body: <p>Quick question about the Dijit.Form.DateTextBox</p>
  
  <p><a href="http://docs.dojocampus.org/dijit/form/DateTextBox" rel="nofollow noreferrer">http://docs.dojocampus.org/dijit/form/DateTextBox</a></p>
  
  <p>This page contains the following: "also validates against developer-provided constraints like min, max, valid days of the week, etc."</p>
  
  <p>I can't seem to find documentation allowing me to provide a constraint on the days of the week.  For instance, i need to have a DateTextBox which only allows users to choose a date that occurs on a Sunday.</p>
  
  <p>I'd appreciate any help with this.  Thanks!</p>
