How can I run a quartz schedule on mondays and tuesdays every two weeks?

Question

I used the below way to run the schedule on every two weeks on mondays.

ITrigger trigger = TriggerBuilder.Create()
                                    .StartAt(DateBuilder.DateOf(StartHour, StartMinute, StartSeconds, StartDate, StartMonth, StartYear))
                                    .WithCalendarIntervalSchedule(x => x.WithIntervalInWeeks(Int32.Parse(nWeekInterval)))
                                    .EndAt(DateBuilder.DateOf(0, 0, 0, EndDay, EndMonth, EndYear))
                                    .Build();

But how can I use a single schedule to run on mondays and tuesdays as well. Please advice.

Answer 1

You can specify days of the week with DailyTimeIntervalScheduleBuilder

var onMondayAndTuesday = DailyTimeIntervalScheduleBuilder.Create()
                         .OnDaysOfTheWeek(new DayOfWeek[] { DayOfWeek.Monday, DayOfWeek.Tuesday });

var trigger = TriggerBuilder.Create()
                            .StartAt(DateBuilder.DateOf(StartHour, StartMinute, StartSeconds, StartDate, StartMonth, StartYear))
                            .WithSchedule(onMondayAndTuesday)
                            .WithCalendarIntervalSchedule(x => x.WithIntervalInWeeks(Int32.Parse(nWeekInterval)))
                            .EndAt(DateBuilder.DateOf(0, 0, 0, EndDay, EndMonth, EndYear))
                            .WithIdentity(triggerKey)
                            .Build();

Answer 2

I would create one job with two different triggers. Each trigger fires biweekly (or semi-monthly).

Answer 3

Use the following expression to schedule a job to run on alternate Mondays and tuesdays.

0 0 0 1-7,15-21,29-31 * 1,2 *

Here is how the expression is described.

0 -- 0th sec

0 -- 0th min

0 -- 0th hr

1-7,15-21,29-31 -- on alternate week of the month

• -- any month

1,2 -- On Monday and Tuesday

• -- Any year.
