How it works

  1. Hourly Cron Expression On The Hour is a practical five-field cron schedule for hourly aggregation and status snapshots. The expression `0 * * * *` is designed for the common minute, hour, day-of-month, month, and day-of-week format used by many Linux crontab and scheduler interfaces.
  2. Use this preset when you want a known-good starting point that can be copied into a deployment script, CI scheduler, container task, or application job runner. The preview below explains the fields and shows the next matching run times using deterministic local logic.
  3. Running at minute zero creates clean hourly boundaries for metrics and logs. Cron dialects are not perfectly portable: Quartz, Kubernetes CronJob, GitHub Actions, systemd timers, and cloud schedulers may interpret seconds, time zones, or special modifiers differently. Always verify the expression in the scheduler that will execute it.

Limitations

  • This preset targets a common workflow and should be reviewed against your production environment.
  • Generated output is deterministic and local-first, but scheduler, log, or infrastructure dialects can vary.
  • Use the full parent tool when you need to adjust fields, ports, options, or sample inputs.

FAQ

Can I copy the Hourly Cron Expression On The Hour cron expression directly?

Yes, for common five-field cron schedulers. Review timezone and dialect behavior before using it in production.

Does this cron preset run on the server?

No. The explanation and next-run preview are generated locally in your browser or at static build time.

Why are Quartz seconds not included?

PureToolkit cron presets intentionally target the common five-field format to keep output predictable.
