Pure Frontend ยท Decode Cron to Plain Text ยท Next Run Times
Zero Dependencies ยท Works OfflineCron expressions are the standard format for scheduling tasks in Linux/Unix, but the five asterisks are hard to read. This tool converts Cron expressions into clear field-by-field descriptions and calculates the next 10 execution times, helping you verify your schedule configuration. All processing happens in your browser.
Step 1: Enter Cron expression, e.g. */5 * * * * means every 5 minutes.
Step 2: Tool auto-decodes each field and shows next 10 execution times.
Step 3: Click Load Example for common patterns. Shortcuts: Ctrl+Enter, Ctrl+Shift+C.
Verify crontab, Kubernetes CronJob, and GitHub Actions schedules match your expectations.
Convert Cron to readable descriptions for clear team communication about execution plans.
Debug unexpected Cron behavior by verifying actual execution times.
Cron Format: Standard 5 fields are min/hour/day/month/weekday. Some systems extend to 6 (with seconds) or 7 (with year). Special chars: * any, */n interval, , list, - range. Note: 0 and 7 both mean Sunday. Different systems may have varying Cron implementations (Spring 6-field, AWS EventBridge custom format).
