What is Google Calendar

What is Google Calendar
Google Calendar is a free time-management web application offered by Google. It became available on April 13, 2006 and after over 3 years, as of July, 2009 it is no longer in beta stages. While users are not required to have a Gmail account, they are required to have a free Google Account in order to use Google Calendar. The interface of Google Calendar, designed by Kevin Fox (who also designed Gmail and the second version of Google Reader), is similar to desktop calendar applications such as Microsoft Outlook or iCal on Mac OS X.

User friendly Google Calendar
The Ajax-driven interface enables users to view, add, and drag-and-drop events from one date to another without reloading the page. It supports view modes such as weekly, monthly, and agenda. Users can "quick add" calendar events by typing standard English phrases, such as "Dinner with Michael 7pm tomorrow". Users can also set the number of days to show in their custom view mode. All events in a Google Calendar can be commented on by its users.
