On several occations, I have spin up my test host in AWS and left if running for months without using it. I wanted this instance to shutdown on timer. I can always start it up anytime - that does not bother me.
Here is sample code;
[root@ip-172-30-0-62 ~]# crontab -l
* * * * * date >> /var/log/cron-date
* * * * * /root/shutdown-timer >> /var/log/shutdown.log 2>&1
[root@ip-172-30-0-62 ~]# cat shutdown-timer
