Answer 1

Initialize the default date when you attach the date picker as so:

$(function() {
  $( "#birthday_text" ).datepicker( {defaultDate:"0000-00-00",dateFormat: "yy-mm-dd" });

});​

jsfiddle with demo

Update : Since you say that the "defaultDate" parameter is giving you problems, try this alternative:

  $( "#birthday_text" ).datepicker({dateFormat: "yy-mm-dd" } );
  $( "#birthday_text" ).val('0000-00-00');

jsfiddle for alternative.

You'll want to set the default date with the options when you're setting the datepicker up. Check out their docs on default date: http://jqueryui.com/demos/datepicker/#option-defaultDate . Also, there is a chance that the datepicker control won't let you use 0000-00-00 since it isn't a valid date. Have you tried with something other than all zeros?
