Datepicker - How do I restrict the months shown with maxDate value in place.

Datepicker - How do I restrict the months shown with maxDate value in place.

I currently have my datepicker to allow to pick from current year to 2017...ie)

$("#datearrival").datepicker({minDate: 0, maxDate: "+5Y", changeMonth: true, changeYear: true});
 $("#datedeparture").datepicker({minDate: 0, maxDate: "+5Y", changeMonth: true, changeYear: true});

If i want to also only have certain months shown in each of the +5 years....how can i achieve this?

Thanks
