   * the weekend (Saturday or Sunday)
   * 
   * @param date
   *          Date to check, cannot be null
   * @return TRUE is Saturday or Sunday
   */
  public static boolean isWeekend(LocalDate date) {
    DayOfWeek dayOfWeek = DayOfWeek.of(date.get(ChronoField.DAY_OF_WEEK));
    switch (dayOfWeek) {
    case SATURDAY:
    case SUNDAY:
