I, I use the syntax: °° xxx yyy zzz <2024-08-29 Thu 15:45> To set a date. How can I set an advice (1 or 2 hour) before? I mean: I would receive an alert 1 or 2 hour before that alert me of the new appointment . Can I set emacs using init.el or something else to advise me some time before that there is a date? Or is there some specific syntax that help me to alert some time before?
Thank you Renato
