# Trigger That Executes Every Week ## Using org.quartz.helpers.TriggerUtils (TriggerUtils note: in 1.5.x, org.quartz.helpers.TriggerUtils has moved to org.quartz.TriggerUtils.) Trigger That Executes Every Wednesday at 3:00PM
    Trigger trigger = TriggerUtils.MakeWeeklyTrigger(TriggerUtils.WEDNESDAY, 15, 0);
    trigger.setName("trigger1");
    trigger.setGroup("group1");
## Doing it manually If you would like a Trigger that executes every week on a specified day of the week at a specified time, use CronTrigger: CronTrigger That Executes Every Wednesday at 3:00PM
    Trigger trigger = new CronTrigger("trigger1", "group1");
    trigger.setCronExpression("0 0 15 ? * WED");
If you don't care what time it runs (only the period is important), you can use SimpleTrigger (note that startTime will be the time when the trigger was instantiated): SimpleTrigger That Executes Every 7 Days
    Trigger trigger = new SimpleTrigger("trigger1", "group1");
    //7(days per week) * 24(hours per day) * 60(minutes per hour) * 60(seconds per minute) * 1000(milliseconds per second)
    trigger.setRepeatInterval(7L * 24L * 60L * 60L * 1000L);
Technically, if you want to specify the time the trigger will fire, you can use a SimpleTrigger, but it's a lot of work to get the startTime right: SimpleTrigger That Executes Every Wednesday at 3:00PM
    java.util.Calendar startTime = java.util.Calendar.getInstance();
    startTime.set(java.util.Calendar.HOUR_OF_DAY, 15);
    startTime.set(java.util.Calendar.MINUTE, 0);
    startTime.set(java.util.Calendar.SECOND, 0);
    startTime.set(java.util.Calendar.MILLISECOND, 0);
    startTime.set(java.util.Calendar.DAY_OF_WEEK, java.util.Calendar.WEDNESDAY);

    //if the startTime will be before the current time, move to next week
    if (startTime.getTime.before(new Date()) {
       startTime.add(java.util.Calendar.DAY_OF_MONTH, 7);
    }

    Trigger trigger = new SimpleTrigger("trigger1", "group1");
    trigger.setRepeatCount(SimpleTrigger.REPEAT_INDEFINITELY);
    trigger.setStartTime(startTime.getTime());
    //7(days per week) * 24(hours per day) * 60(minutes per hour) * 60(seconds per minute) * 1000(milliseconds per second)
    trigger.setRepeatInterval(7L * 24L * 60L * 60L * 1000L);
