Müllkalender .ics der Stadt Mannheim aufhübschen

Die .ics-Datei, die man von bekommt, kann man mit ein bisschen Geduld und Arbeit im Code-Editor der Wahl recht gut aufhübschen. Die Notizen hier sind für mich selbst, aber wer mag, kann sich ja auch daran versuchen. Ich habe die Termine nicht in einem eigenen Kalender, sondern in einem allgemeinen Termine-Kalender, darum füge ich vor jeden der Einträge den Begriff Müllabfuhr. Dann weiss man Bescheid.


  • .ics datei öffnen (im format windows 1252?)
  • datei speichern als UTF-8
  • Ersetze ;CHARSET=UTF-8 durch empty string (braucht man nicht, die ganze datei ist jetzt eh utf-8)

This code is based heavily on the instructions given on
Many hours on Stackoverflow have been spent trying to make this.
I tried to clean it up, make it readable, add a nicer UI and feedback about errors.
If you like this, use this or it helps you, I'm happy to hear about it.
Drop me a line if you have feedback, too.
