Remarks

The trigger will fire every N (see RepeatInterval) units of calendar time (see RepeatIntervalUnit) as specified in the trigger's definition. This trigger can achieve schedules that are not possible with ISimpleTrigger (e.g because months are not a fixed number of seconds) or ICronTrigger (e.g. because "every 5 months" is not an even divisor of 12).

If you use an interval unit of Month then care should be taken when setting a StartTimeUtc value that is on a day near the end of the month. For example, if you choose a start time that occurs on January 31st, and have a trigger with unit Month and interval 1, then the next fire time will be February 28th, and the next time after that will be March 28th - and essentially each subsequent firing will occur on the 28th of the month, even if a 31st day exists. If you want a trigger that always fires on the last day of the month - regardless of the number of days in the month, you should use ICronTrigger.
