Quartz.Net - Quarterly starting from today

How do you create a trigger that is triggered every 3 months (quarterly) starting today.

I though i could do something as simple as

tr = TriggerUtils.MakeHourlyTrigger(2190);
// (365 / 4) * 24 hours = 2190

I don't think this is best way t开发者_如何学Co solve this. I though there might be some fancy cron trigger way of solving it?

The fields in cron are

1. Seconds
2. Minutes
3. Hours
4. Day-of-Month
5. Month
6. Day-of-Week
7. Year (optional field)

So you might like

0 0 0 1 */3 ?

Which will fire every 3 months on the first of the month at midnight.
