Cron Parser decodes any 5-field cron expression into a plain-English description and shows the next 10 scheduled run times with relative timestamps. Paste a cron from a crontab, GitHub Actions schedule, or Kubernetes CronJob and understand when it runs next. Supports all standard operators: *, /, -, and comma-separated lists. Runs entirely in your browser.
A cron expression is a five-field (or six-field, with seconds) string that defines a recurring schedule. Cron originated in Unix systems and is now used everywhere — GitHub Actions, AWS EventBridge, Kubernetes CronJobs, Vercel scheduled functions, and most CI/CD platforms.
