使用步骤
如何使用
- Enter exactly five cron fields separated by spaces.
- Review the plain-English explanation and any field-specific error.
- Copy the explanation or keep the expression for your own scheduler.
Standard five-field syntax
Crontab Guru accepts the conventional minute, hour, day of month, month, and day of week format. Each field supports wildcards, ranges, steps, and comma-separated lists.
Local validation
Parsing happens in your browser. The tool checks each value against its field range and points to the field or token that needs correction. It does not install or run a cron job.
常见问题
你可能还想知道
Which cron fields are supported?
The standard five fields are supported: minute, hour, day of month, month, and day of week.
Can I use names such as MON or JAN?
This version uses numeric fields for predictable cross-platform parsing. Use 1–12 for months and 0 or 7–6 for Sunday through Saturday.
Does this schedule a job?
No. It only explains and validates text locally; add a reviewed expression to your own cron implementation.
