Quartz Cron expression :Run every 15 days ie twice in a month

Question

I want to set the scheduler with a quartz cron expression which will trigger every 15 days ,for example 1st and 15th of every month.The 0 15 10 15 * ? is triggering only on 15th of every month.

Answer 1

I have tested this and the following expression works fine

        "0 0 0 1,15 * ?"

the 1,15 statement fires triggers on 1st and 15th of every month at 00:00 hours. You can change the first three zeroes to fire them at a particular time you want.

the 1st zero -> seconds

the 2nd zero -> minutes

the 3rd zero -> hours
