Component - GCalendar

Displays events from Google Calendar. Different views are available, month view is default. The free version doesn't allow directly add and edit the events, it should be done directly in Google or via the desktop clients like i.e Mozilla Thunderbird

The module named Next milestone in right column is one of the GCalendar modules. It shows the time remained until the nearest event and also a data of current event (that is started but not yet ended).
