Google Calendar is a free time-management web application offered by Google. Google Calendar allows multiple calendars to be created and each can be shared, either read-only or with full edit control, and either with specified people or with everyone known as public calendars.

Since it is a web-based application, it is accessible from virtually any operating system, provided that the OS has a browser which supports the required web technologies.

Google’s New Calendar Feature

With the recent updates, you can be now edit and create events. First only viewing was possible. While logged into your Google account, and by searching “schedule appointment” or “add event” Google delivers a dynamic knowledge graph box that lets you automatically add an event to your Google calendar without leaving the search page.

By clicking the “Create event” link will be automatically added to the event to your calendar without opening the calendar.

Google Calendar was also integrated with other Google services such as:

Gmail:  Google’s webmail service. When an e-mail that contains trigger words (such as “meeting,” or dates and times) arrives, an “add to calendar” button is automatically displayed alongside it.

iGoogle: The user-designed Google homepage, in which users could choose and organize content in the form of ‘gadgets. The calendar was shown as a module on one’s homepage. This “gadget” offered options to edit how the time is displayed, which day the week starts on, and a link to “Add Event.”

Google Desktop: Google’s desktop search software for Windows or Mac OS X. The mini-calendar gadget allowed one to view their events without having to open their browser. One could place it on their desktop or leave it docked in the sidebar.

However, iGoogle and Google Desktop service were discontinued later.
