Gcal events drupal hosting
Let me start here a list of drupal modules working with google calendars. There are many, different, and some unfinished work.
[name+link],[7.x version or status],[some details]
fullcalendar. 7.x-2.0, integration with google calendar is easy and limited (add a fullcalendar google calendar import field to the view);
gcal. 7.x-1.0-rc1, an implementation on google calendar API, I never tried it. The doc says it can: 1) Create, update, delete, get secondary Calendars; 2) Fetch single Calendar setting and list of settings; 3) Fetch Color settings; 4) Create, update, delete, get, move Events; 5) Create, delete, get Acl; 6) Create, update, delete, get CalendarList; 7) FreeBusy checking with events, quickAdd for events Current release includes. Not yet accomplished: 8) Import events and other features.
gcal_events. 7.x-1.x-dev, I never tried it. It display a block of upcoming events from a google calendar xml feed.
date_ical. 7.x-2.13, I never tried it (yet, but I chose this solution). iCalendar is a standard internet calendar format (google calendar can export ical too). date_ical provides ical support in Drupal, provides a plugin for Views to enable exporting your site's calendar as an iCal feed, and a plugin for Feeds to enable importing external iCal feeds into your site's calendar.
agenda. 7.x-1.4, I never tried it. Display a list of upcoming events from Google Calendar as a block.
event_GCalendar. not finished, Google Calendar API.
