Google has opened up yet another beta program. This time, the company is showcasing its Calendar service. Google Calendar is fully integrated with GMail and can even recognize dates from email messages and add them to your calendar.
Google Calendar features the ability to share calendar information with family and friends, integrated search, mobile access with event reminders and notifications and of course it's absolutely free. The service supports calendar data from Apple iCal, Microsoft Outlook, Yahoo! Calendar and any application that support .XML or .CSV files.
Google Calendar supports IE 6.0+ and Firefox 1.07+ on Mac, Linux and Windows platforms.
