Question

As usual, I’m having trouble with setting a Cron timer expression for a Quartz job. If I want to run a job daily at 2245 hours, should the expression be:

0 45 22 * * ?

Answer 1

Their tutorial is pretty nice though 🙂

The field order is

second minute hour dayofmonth month dayofweek year

Year is an optional field.

* means every and dayofmonth and dayofweek can also take the ? value, meaning no specific value. Typically one of the fields will get the ? value.

So your trigger says:

On second 0 of minute 45 of hour 22 of any every in the month, every month,
no matter what weekday

Should work.
