The Key Features
* Text recognition - In adding an event, or detecting a new event from Gmail, Calendar automatically detects event-specific words and suggests the adding of a new event with data auto-structured.
* Manage Multiple Calendars - set up multiple calendars (work, personal, etc) and view them separately or together.
* Heavy Gmail integration - Gmail recognizes when messages include event information, so when you get emailed about an event, you can add it to Google Calendar with just a couple clicks. Google Calendar links on the right side of the Gmail page.
* Sharing - Calendars can be shared with others, and you can subscribe to others’ shared calendars. Read/write permissions can be granted on a per user basis. Calendars can be published via a web page or via RSS, so readers do not need to be on the Google Calendar platform.
* Importing - You can import events from other calendar programs, including Yahoo Calendar and Microsoft Outlook. Click “Settings,” then “Import Calendar”.
* Calendar Search
