KOrganizer/Kalender
Kalender-Datei
Beide Standards werden von einer großen Anzahl anderer Kalenderprogramme unterstützt und auch von anderen Geräten wie z. B. Mobiltelefonen.
KOrganizer is able to directly load the files and work with them in a network-transparent way. This allows you, for example, to have only one calendar, which is accessible from the office and from home without the need for copying or syncing.
