Install cron by entering the following commands in the terminal:

process scheduling daemon
The cron daemon is a background process that runs particular programs at particular times (for example, every minute, day, week, or month), as specified in a crontab. By default, users may also create crontabs of their own so that processes are run on their behalf. . Output from the commands is usually mailed to the system administrator (or to the user in question); you should probably install a mail system as well so that you can receive these messages. . This cron package does not provide any system maintenance tasks. Basic periodic maintenance tasks are provided by other packages, such as checksecurity.
