Scheduling and getting notifications in a desktop or window manager environment

[sirgazil]

Hello,

I was wondering if you could share the software you use to schedule events 
(e.g. meetings, special dates, taking pills, etc.) and get notified about them 
in the form of desktop notifications or something like that.

I tried GNOME Calendar some time ago in the Guix System, I liked its 
simplicity, but it was not reliable (notified sometimes, sometimes not). 

Thanks,
