We don't run VLC as a background app that is aware of the date or time. However, you can probably script that or use Shortcuts.app to achieve this feature.

I used iTunes Alarm to play an iTunes radio stream when my computer awakened in the morning. No technical knowledge was needed. But Apple disabled most of iTunes so I use VLC to play online music stations. I dont know anything about scripts. Shortcuts.app does not exist. Is there an VLC alarm? Or another very simple method using VLC to awaken me with streaming music?
