Die Datei Event.csv hat folgenden Aufbau:

JJMMTT;Eventtext (mit Blanks und ohne Umlaute)
181201;Dezember
181202;1. Adventsonntag
181209;2. Adventsonntag
181216;3. Adventsonntag
181223;4. Adventsonntag
...

Die Datei JJ.csv (z.B. 17.csv) enthält die Zeiten der Sonnenauf- und untergänge und sieht wie folgt aus:

TTMM;Auf;Unter;Auf;Unter
0101;07:46;16:11;466;971
0201;07:45;16:12;465;972
0301;07:45;16:13;465;973
0401;07:45;16:14;465;974
0501;07:45;16:15;465;975
0601;07:45;16:16;465;976
...

Die Daten können z.B. hier https://www.zamg.ac.at/cms/de/klima/klimauebersichten/ephemeriden bezogen werden und müssen (mit Excel) entsprechen aufbereitet werden. Die letzten beiden Parameter sind die Anzahl der Minuten ab 00:00 Uhr.
