It sounds like you have your computer scheduled to wake up at a certain time but it's not. I would use this section of the following article to help you get that resolved:
If your Mac doesn't sleep or wake when expected
- Reset the SMC.
- Reset NVRAM.
- Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
- Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions.
- Try to isolate the issue by using another user account.
Thank you for using Apple Support Communities.
