Quartz的BaseCalendar层次结构如下：

在本例中主要用到了AnnualCalendar,它的作用是排除排除每一年中指定的一天或多天.
AnnualCalendar类说明如下：

This implementation of the Calendar excludes a set of days of the year. You may use it to exclude bank holidays which are on the same date every year. 

其它相应的有:CronCalendar(表达式),DailyCalendar(指定的时间范围内的每一天),HolidayCalendar(排除节假日),MonthlyCalendar(排除月份中的数天),WeeklyCalendar(排除星期中的一天或多天)
具体代码如下：

 //法定节日是以每年为周期的，所以使用AnnualCalendar  
        AnnualCalendar holidays = new AnnualCalendar();        
        // ②五一劳动节  
        Calendar laborDay = new GregorianCalendar();  
        laborDay.add(Calendar.MONTH, 5);  
        laborDay.add(Calendar.DATE, 1);  
        // ②-1：排除的日期，如果设置为false则为包含  
        holidays.setDayExcluded(laborDay, true);  
        // ③国庆节  
        Calendar nationalDay = new GregorianCalendar();  
        nationalDay.add(Calendar.MONTH, 10);  
        nationalDay.add(Calendar.DATE, 1);  
        // ③-1：排除该日期  
        holidays.setDayExcluded(nationalDay, true);          
        //添加到时间集合到任务调度器中
        sched.addCalendar("holidays", holidays, false,false);           
        //当前时间15秒后运行
        Date startTime = nextGivenSecondDate(null, 15);
        //绑定任务
        JobDetail job = newJob(SimpleJob.class)
            .withIdentity("job1", "group1")
            .build();        
        //触发器
        SimpleTrigger trigger = newTrigger() 
            .withIdentity("trigger1", "group1")
            .startAt(startTime)
            .withSchedule(simpleSchedule()
                    .withIntervalInHours(1)//重复间隔：小时为单位
                    .repeatForever())
            .modifiedByCalendar("holidays")
            .build();        
       
        //运行时间
        Date firstRunTime = sched.scheduleJob(job, trigger);       
        log.error(job.getKey() +
                " will run at: " + firstRunTime +  
                " and repeat: " + trigger.getRepeatCount() + 
                " times, every " + trigger.getRepeatInterval() / 1000 + " seconds");        
      
        //启动调度器
        sched.start();
