The extension consists of two components:

• A content element that creates a download link for one or more TYPOlight calendars and a given time period. You may use the download link to subscribe to this calendar(s) from within a calendar application like Apple iCal.
• An import wizard to import iCal files (.ics) which have been uploaded into the file manager.

Single calendars can be created as automatic iCal subscriptions (.ics files) in the TYPOlight root directory (similar to RSS/Atom feeds). These files can be subscribed by calendar applications using the URL to the subscription file.

calendar_ical is available in the TYPOlight Extension Repository for Download.
