Things to watch with this schedule

  • 6,0 and 0,6 are equal. A range 6-0 is invalid in cron because ranges cannot wrap; list the days instead or write SAT,SUN.

Kubernetes CronJob

Kubernetes uses the same five fields. Set spec.timeZone (stable since Kubernetes 1.27), otherwise the schedule follows the time zone of kube-controller-manager.

apiVersion: batch/v1
kind: CronJob
metadata:
  name: every-weekend-at-midnight
spec:
  schedule: "0 0 * * 6,0"
  timeZone: "Etc/UTC"
  concurrencyPolicy: Forbid
  startingDeadlineSeconds: 300
  jobTemplate:
    spec:
      template:
        spec:
          restartPolicy: OnFailure
          containers:
            - name: job
              image: debian:bookworm-slim
              command: ["/bin/sh", "-c", "/app/run-job.sh"]

GitHub Actions

Workflow schedules use five-field cron in UTC and run only from the default branch. Runs at minute 0 are the most likely to be delayed or dropped when GitHub is busy; an odd minute such as 7 or 23 starts more reliably.

on:
  schedule:
    - cron: '0 0 * * 6,0'   # UTC

jobs:
  run:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: ./run-job.sh

systemd timer

The equivalent OnCalendar= value is Sat,Sun *-*-* 00:00:00. Check it with systemd-analyze calendar 'Sat,Sun *-*-* 00:00:00', which prints the next elapse time. Persistent=true runs a missed job after downtime, which classic cron never does.

AWS EventBridge

EventBridge rules take six fields (minute, hour, day-of-month, month, day-of-week, year) in UTC; EventBridge Scheduler can use a time zone. One of day-of-month and day-of-week must be ?, and day-of-week runs 1-7 from Sunday, so names are used here.

cron(0 0 ? * SAT,SUN *)

Quartz Scheduler (Java)

Quartz adds a leading seconds field and needs ? in either day field; days of the week are 1 (SUN) to 7 (SAT).

0 0 0 ? * SAT,SUN

Spring's @Scheduled(cron = ...) also uses six fields, but numbers days of the week 0-7 with Sunday as 0 or 7, like Unix cron; the names shown above work in both.
