Cron Generator
Assemble the five conventional cron fields for minute, hour, day, month, and weekday. The tool drafts an expression; it does not create a scheduled job on your server.

How to use this tool
Select a preset or enter numbers, wildcards, and ranges in the fields. Check whether the target scheduler expects a seconds field, and configure its time zone separately.
Results and examples
In conventional five-field cron, 0 9 * * 1 describes Monday at 09:00. Check the destination scheduler’s weekday and day-of-month semantics before saving the expression there.
Limitations
- No live server time zone or next execution is queried.
- Extra fields and combined day conditions can vary between schedulers.
