Cron Parser
Human-readable cron
What is Cron Parser?
Paste an existing cron expression and get a plain-English translation plus the next 10 scheduled run times. Useful for auditing a crontab you inherited, double-checking whether a schedule really means what you think, or explaining a cadence to a non-technical stakeholder.
How do I use Cron Parser?
- Paste the cron expression (e.g. "0 9 * * 1-5").
- Read the English translation and the next-10 runs.
When should I use Cron Parser?
Cron Parser is for reading schedules. To author a new schedule interactively, use Cron Generator, which offers the 5-field builder plus presets.
What does the parser explain?
A plain-English description ("At 9:00 AM every Monday"), a list of the next N fire times, and a field-by-field breakdown. Useful for understanding cron rules you inherited.
Does it handle 6-field and 7-field cron?
Yes. Both Quartz-style (7 fields with year) and node-cron (6 fields with seconds) are detected and parsed.
Can I change the timezone?
Yes — the preview times update when you change the timezone. Default is your browser's local timezone.
Is my file uploaded anywhere?
No. Everything runs in your browser. Your files never leave your device, and there is no server component for this tool.
