Dating yourself

After being dissatisfied with the complexity of JavaScript date widgets, I wrote this snippet to create a natural language solution, backed by the Datejs library.  It works by parsing the text a user entered on blur. 

It's a little rough at the moment, but a few refinements could make it just as effective as some of the more complicated implementations out there.

$('input.datefield').blur(function () {
  var field = $(this);
  var date = Date.parse(field.val());
  if (date) {
    field.val(date.toString("hh:mm tt"));
  }
});
