It might if you're using cron to shut the machine down.

Anacron will try to run cron jobs that were missed whilst a machine was
down. So if you have your machine set to shut down using a cron.daily
entry, and you were away for the weekend and didn't power up the
machine, anacron would see to it that jobs from cron.daily that had been
"missed" were run shortly after the next reboot. You probably don't want
a shutdown to happen then.
