Construct a 5-field cron expression (minute hour day-of-month month day-of-week) by editing each field or picking a preset like 'every hour', 'daily at midnight', 'weekdays at 9 AM'. The human-readable description is generated by cronstrue so you can sanity-check what you've built before pasting it into crontab, GitHub Actions, Vercel Cron, or Kubernetes CronJob. The inverse tool; explain an existing cron; is our `crontab-explainer`.
