About Cron Expression Parser
Cron Expression Parser turns a 5-field UNIX cron string (minute, hour, day-of-month, month, day-of-week) into a human-readable description, breaks down each field, and shows the next five times the schedule will fire (in your local timezone).
Useful for debugging crontab entries, double-checking that '*/15 * * * *' really means every 15 minutes, and previewing when a Vercel/GitHub Actions cron will trigger.
