Cron job fails to run per schedule

Bug Reports

Hi Community,

I have a periodic job running with the following cron:

# Deploy the website every Mon, Wed, Fri, Sat, and Sun at 5:00 UTC
periodic_deploy:
triggers:
    - schedule:
        cron: "0 5 * * 0,1,3,5,6"
        filters:
        branches:
            only: master
jobs:
    - site

This job, however, does not always run. Who knows why?

So the job often doesn’t run on Friday, even though I have 5 defined as the day of week.

Just to clarify, I’ve added the cron schedule to CircleCI in late December and not just recently. So from my understanding it should run on the missed Fridays in the above table too.

Do you have an idea what can cause this? Thanks!

Hi @Jura,

Thanks for reaching out to CircleCI community support.

As per the provided detail, I can see that job ran on 19th February. Did it also run on 26th Feb?

Could you please provide the build link so that I can investigate further? If you are not comfortable sharing the build link here, please submit a ticket to our Support.
