@ Override public boolean isNonWorkingDay ( final E date ) { if ( date != null && ( holidayCalendar . getEarlyBoundary ( ) != null || holidayCalendar . getLateBoundary ( ) != null ) ) { checkBoundary ( date ) ; } return isWeekend ( date ) || holidayCalendar . isHoliday ( date ) ; }
is the given date a non working day?
