This Events Calendar site was developed using the Kohana PHP framework (v3.1).
The calendar displays a filtered, searchable list of events that is aggregated from multiple Google Calendars.
Zend_Gdata was used to interface with the Google Calendar API, and iCalcreator was used to generate iCal feeds for use in the University's mobile applications.
Two files in the app/config directory contain the database and Google account information. The Events Calendar application will download and aggregate all of the Google Calendars owned by the account specified in app/config/google.php.
