What is Cron Expression Parser & Human Explainer?

The Cron Expression Parser explains what a cron schedule means in plain English — for example "*/15 * * * *" becomes "Every 15 minutes". Paste an expression from a crontab, Kubernetes CronJob, GitHub Actions workflow or cloud scheduler to confirm it runs when you expect, or start from presets such as every hour, daily at midnight, weekdays at 9 AM or weekly on Sunday.
