How to Use This Cron Generator

  1. Choose your format — select Unix (5 fields) or Quartz (6-7 fields) depending on your platform.
  2. Set each field — use the visual selectors to configure minute, hour, day of month, month, and day of week.
  3. Review the expression — see the generated cron expression and its human-readable description in real time.
  4. Preview next runs — check the next scheduled run times with your preferred timezone to confirm the schedule is correct.
  5. Export or copy — copy the expression to your clipboard or export directly as a Kubernetes CronJob YAML, GitHub Actions workflow, or systemd timer unit.
