Restrict the options on a jQueryUI date picker to allow only weekdays at a minimum of 2 business days in the future

jQueryUI-business-days-filter.js

$(document).ready(function() {
  $('.date').datepicker({ 
  	dateFormat: 'yy-mm-dd', 
  	minDate :  setRestrictedDates(),
  	beforeShowDay: $.datepicker.noWeekends
  });

});

function setRestrictedDates(){
	var today = new Date();
	//default to second business day
	var offset = 2;
	switch(today.getDay())
	{
		//sunday -> wednesday
		case 0:
			offset = 3;
			break;
		//thursday -> monday
		case 4:
		//friday -> tuesday
		case 5:
		//saturday -> wednesday
		case 6:
			offset = 4;
			break;
	}
	return offset;
}

setRestrictedDates uses a switch statement for read-ability, not sure if this is the 'best' way of doing it.
