How to schedule raspberry pi to shutdown every day at a certain time?

Question

I’m trying to schedule my pi 3b+ (buster) to shutdown automatically at a certain time, but it’s not listening to me. What am i doing wrong?

Sudo crontab -e

Then i add (nano) this to bottom of the file:

36 08 * * * sudo /sbin/shutdown –h now

This should tell it to shutdown everyday at 8:36am, correct?

Try adding a @reboot shutdown -h 08:36 line. Which uses the shutdown command's scheduler. — Dougie, Commented Mar 9, 2020 at 14:18
Not working. Also tried adding that in autostart file. No luck. — Fun4stuff, Commented Mar 9, 2020 at 15:45
I got it. It was setting it to occur the following day. I had been setting it for a few mins after current time to test it, which wasn’t working because it was setting it to occur 24 hrs later. Thanks all! — Fun4stuff, Commented Mar 9, 2020 at 17:48

Open crontab by crontab -e or export VISUAL=nano; crontab -e which is much easier to edit. Then, add the line below at the end of that:

@reboot /sbin/shutdown -h 08:36

You can also follow your procedure that mentioned. Gonna work.
