How to Use

Build a cron expression visually by selecting values for each field: minute, hour, day of month, month, and day of week. Use the dropdowns and checkboxes to set specific values, ranges, or intervals. The tool generates the cron expression and shows a human-readable description of the schedule along with upcoming execution times.

Common Use Cases

  • Creating cron schedules for automated backup scripts without memorizing cron syntax
  • Building CI/CD pipeline schedules in GitHub Actions or GitLab CI
  • Setting up scheduled database maintenance tasks on Linux servers
  • Configuring periodic cleanup jobs in Kubernetes CronJob manifests

Frequently Asked Questions

How is this different from the Cron Expression Parser?

The Crontab Generator helps you build cron expressions visually (from UI to expression). The Cron Expression Parser does the reverse: it takes an existing expression and explains what it means.

Can I generate cron expressions for intervals like "every 2 hours"?

Yes. Use the "every N" option for any field. For example, selecting "every 2" in the hour field generates */2 in the hour position, which runs the job at 0:00, 2:00, 4:00, and so on.

Are the generated expressions compatible with all cron implementations?

The tool generates standard 5-field cron expressions compatible with Unix crontab, systemd timers, GitHub Actions, Kubernetes CronJobs, and most scheduling libraries.
