title: JQuery UI datepicker determine if Saturday clicked
body: <p>I am using datepicker and if someone selects a Saturday I want it to update a form select with different options - any idea how to do this?</p>
  
  <p>I thought I could use the onSelect function, but all my attempts thus far do not work.</p>
  
  <p>Any help would be much appreciated!</p>
  
  <ul>
  <li>awesome - that tells me they have selected Saturday, but then how do I change the form select values to represent that. Basically for all days during the week is a set value of options, but the options narrow if a Saturday...</li>
  </ul>
