Full description:

This plugin allows you to import and export Ical files directly in WebApp. So there is no need for curl anymore! You can choose the calender into which you want to import your ics file. If you do not want to import all events, just select those you want.

Since version 1.2 you can manually select the timezone of the imported events, if it doesn't get detected automatically. You can now import/export calendars from the public store too!

Since version 2.0 it is possible to import mail attachments directly to your calendar!

Since 2.0.5 there is a new Settingswidget to make configuration easier.

Since 2.1.0 it is possible to subscribe to external ics calendars.

Tested with exported Google ics files.
