Bootstrap DatePicker, how to set the start date for tomorrow?

How can I set the startDate for tomorrow? I don't see an option in the documentation for Date.today so I can add one more day.

Is there a way to accomplish this?

$(function() {
    $("#appointment_adate").datepicker({
        format: 'yyyy-mm-d',
        autoclose: true,
        startDate: '+1d'    
    });
});
