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();
