What is the cron expression in Quartz Scheduler to run a program at 12 am every midnight GMT.

I have never used quartz before so I am still learning.

Is the expression 0 0 12 * * ? or is that for 12 pm (noon). Could anyone tell me?

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

So in your case:

0 0 0 * * ?

This will fire at midnight, if you want to fire at noon:

0 0 12 * * ?

Or both:

0 0 0,12 * * ?

Have an awesome day!

  • That expression has 7 fields... It's not a valid cron expression
  • plz check it on Cron Maker it's valid @Araymer
  • I just put it in a project and got an exception using @Scheduled(cron = "0 0 0 1/1 * ? *")
  • it's already working on my spring project. @Araymer and your question is 7 filed is Seconds see this quartz-scheduler.org/documentation/quartz-2.x/tutorials/…
  • That's interesting. I get an exception saying that I've too many fields... What version of Spring/Spring Boot are you using?
