Question

Using Quartz.Net and have a need for the same trigger to have multiple Calendars, whilst this isn’t possible I’m looking for suggestions of how to achieve similar functionality.

For example I want to run the job in X minutes and exlude 9-10am every day but be able to block out other times during the day as required.

The code below works fine but if I want to block out another time interval I can’t see a way of doing it.

ISchedulerFactory schedFact = new StdSchedulerFactory();
sched = schedFact.GetScheduler();

CronCalendar cronCal = new CronCalendar("* * 9 ? * * *");
sched.AddCalendar("testCal", cronCal, true, true);

CronTrigger trigger = new CronTrigger("cronTrigger", null, "0 0/1 * 1/1 * ? *");               
trigger.StartTimeUtc = DateTime.UtcNow.AddMinutes(10);
trigger.CalendarName = "testCal";

JobDetail job = new JobDetail("testJob", null, typeof(DumbJob));

sched.ScheduleJob(job, trigger);
sched.start();

Simple test job:

public class DumbJob : IJob
        {
            public DumbJob()
            {
            }

            public void Execute(JobExecutionContext context)
            {
                MessageBox.Show("Dumb job is running");
            }
        }

You can create a chain of calendars. Every calendar can have a base calendar which is also checked when determining whether given time is excluded or included. See CronCalendar’s contructor:

public CronCalendar(ICalendar baseCalendar, string expression)
