Surely this would be easy to fix with a simple script that runs on a VPS to alert you on a platform of your choice, maybe using something like Apprise (https://github.com/caronc/apprise). Get the notification as an email, on Discord, Signal, etc.

This does complicate the system a bit, but still low overhead in my opinion.

Congratulations you invented a calendar with notifications. Which already exists on every digital device, it existed on Nokia phones 30 years ago :)
