Analyser a cron expression and explain its schedule in plain English
Décoder a cron expression (e.g. '0 9 * * 1-5') into a human-readable schedule, and generate cron expressions from natural language.
- 1
Cron expressions are compact but cryptic: five fields (minute hour day-of-month month day-of-week) encode complex schedules. Parsing them into plain English prevents scheduling mistakes; generating them from description avoids syntax errors.

Paste a cron expression (e.g. '*/15 9-17 * * 1-5'). The tool explains it in plain English ('At every 15th minute past the hour, between 09:00 and 17:00, Monday through Friday') and lists the next few execution times.

Questions fréquentes
- What is the difference between 5-field and 6-field cron?
- Standard cron uses 5 fields (minute hour dom month dow). Some systems add a sixth field for seconds (at the start) or year (at the end). Quartz cron uses 6-7 fields. Check your target system's format before generating.
- Why does my cron run at the wrong time?
- Cron runs in the server's timezone (usually UTC for cloud platforms). '0 9 * * *' means 9:00 server time, not your local time. Either adjust the expression for your timezone offset or set TZ in the crontab/environment.
