Frequently asked questions

What do the five cron fields mean?
Left to right: minute, hour, day of month, month and day of week. An asterisk (*) means "any".
How do day-of-month and day-of-week combine?
With OR: if you set both (neither is *), the job runs when either one matches, not when both match. It is a detail many people —and many sites— get wrong.
What is the "command audit"?
It inspects the command part of the cron line for dangerous patterns (rm -rf, download-and-run, reverse shells, temp paths) and flags them by severity.
