What? rtfm

'man anacron' says:

Description: Anacron can be used to execute commands periodically, with a
frequency specified in days. Unlike cron(8), it does not assume that the
machine is running continuously. Hence, it can be used on machines that
aren't running 24 hours a day, to control daily, weekly, and monthly jobs
that usually controlled by cron.
