About this tool
Paste a cron expression to get a plain-English explanation and a list of upcoming scheduled run times. Supports standard five-field Unix cron (minute, hour, day-of-month, month, day-of-week), six-field expressions with seconds, and shorthand like @daily, @weekly, and @hourly. Useful for debugging CI/CD pipelines, Kubernetes CronJobs, AWS EventBridge rules, GitHub Actions scheduled workflows, and cloud function triggers.
