Hi @Ramakrishna,

currently, cron expressions are not supported. Please have a look at the documentation: https://docs.zeebe.io/bpmn-workflows/timer-events/timer-events.html

Best regards,
Philipp

Hi @Ramakrishna,

there is an open feature request to use a time cycle and defining a specific time.

However, there are different ways to build something similar. One way could be:

  • model a workflow with a timer start event that has a time cycle of P1D (i.e. every day)
  • deploy the workflow at 10am
  • it will create a new instance every day at 10am
5

Another approach might be just to use Spring Boot Scheduler to create new workflow instances every day… Do you have a requirement to have that timer in the workflow definition?

So there is no way of specifying CRON expression in camunda workflow directly?

Hi @rajesh.joshi,

you have picked up an old post from this forum.

It’s implemented now: Timer events | Camunda 8 Docs

Hope this helps, Ingo
