Live calendar app as desktop wallpaper?

Does something like this even exist?

I want to have an actual live calendar set as one of my monitors wallpaper, so it's always there at a glance. I don't want to leave an app open, have it in the tray or taskbar, or have it be interactable so I can accidentally move it otherwise change it.

Probably sounds dumb, but I just don't like notifications that I can miss, and I have memory issues so remembering to open the calendar to remind myself of dates I've forgotten is a bit of a catch 22.
