Triggering

• on.schedule

  • Syntax

    • Minute [0,59]
    • Hour [0,23]
    • Day of the month [1,31]
    • Month of the year [1,12]
    • Day of the week ([0,6] with 0=Sunday)

  • Example

    on:
      schedule:
        - cron: '30 5 * * 1,3'
        - cron: '30 5 * * 2,4'
    
    jobs:
      test_schedule:
        runs-on: ubuntu-latest
        steps:
          - name: Not on Monday or Wednesday
            if: github.event.schedule != '30 5 * * 1,3'
            run: echo "This step will be skipped on Monday and Wednesday"
          - name: Every time
            run: echo "This step will always run"

    • This example triggers the workflow to run at 5:30 UTC every Monday-Thursday, but skips the Not on Monday or Wednesday step on Monday and Wednesday.
