iMac Retina 5K, 27-inch, 2019 Ventura 13.6 Poweron/Poweroff schedule not working.

I have a iMac Retina 5K, 27-inch, 2019 and since the change in scheduling Poweron/Poweroff using Terminal, I have a strange problem. I cannot set both Poweron and Poweroff. I can set either one but when I try to set both, it cancels the first one and shows only the second one. I set it some time ago when the system changed to using Terminal and that was OK but recently I needed to change the times and that is when this problem started.

All I want to do is Power it off at 23:45 and Power it on at 07:15.

iMac 27″, macOS 13.5

Here is an example to set power/off daily. Just change the time you want:

Separately:

Shut down each day at 9:30 pm:

Sudo pmset repeat shutdown MTWRFSU 21:30:00 and hit return

Enter PW if required

Startup every day at 6:00AM:

Sudo pmset repeat wake MTWRFSU 6:00:00 and hit return

To have both startup and shutdown:

Sudo pmset repeat poweron MTWRFSU 6:00:00 shutdown MTWRFSU 21:30:00

To check if these were set:

Pmset -g sched

To cancel all settings:

Sudo pmset repeat cancel and hit return

Monday=M

Tuesday=T

Wednesday=W

Thursday=R

Well, Thank you, what a dimwit I am.

I had assumed that I had to enter each one separately but I have now entered them together as you suggested and when I checked, there they are.

Thanks again
