When entering the date and time, you must use a 24-hour HH:MM:SS format for the time, format the date as MM/DD/YY, or use a single letter format for specific days of the week. The days of the week are below.

sudo pmset repeat wake W 06:30:00

If you want your Mac to power on every weekday at 6:30 A.M, you would enter:

sudo pmset repeat wake MTWRF 6:30:00

If you want your Mac to restart at 11:00 P.M. every day, you would enter:

sudo pmset repeat restart MTWRFSU 23:00:00

Things to know when scheduling automatic reboot with macOS Ventura

Here are a few more things to know so you don't run into any snags. Your Mac must be awake, and you must be logged in for it to shut down at the scheduled time. If you're not logged in or if your Mac is in sleep, it won't shut down.

If FileVault is turned on, you must log in again upon reboot, so make sure you know the password. Also, if you have any documents open with unsaved changes, this might prevent it from shutting at the scheduled time.

With a scheduled reboot, when you wake up and are refreshed for a new day, your Mac will be too.
