Thus, it can be used to control the execution of daily, weekly, and monthly jobs (or anything with a period of n days) on systems that don't run 24 hours a day.

    /etc/cron.deny – If the cron.allow file does not exist but the /etc/cron.deny file does exist then, to use cron jobs, users must not be listed in the /etc/cron.deny file. Note that if neither of these files exists then, depending on site-dependent configuration parameters, either only the super user can use cron jobs, or all users can use ...

    As with Anacron, it does not assume that the system is running continuously, and can run in systems that do not run all the time or regularly. It aims to replace Vixie-cron and Anacron with a single integrated program, providing many features missing from the original Cron daemon. [3] Some of the supported options permit: [3] run jobs one by one
