Google Calendar Labs is launching with six new features, and though they haven’t been turned on for us just yet, the Google Apps Blog post introduces a few of them by saying, “Try out Next Meeting, which shows you how much time you have to procrastinate. Free or Busy allows you to see which of your friends or coworkers are currently in meetings. And World Clock lets you keep track of different timezones when you schedule meetings.”

Plus, should you want to build your own Calendar features, you can do so with the newly released experimental API. We hope to see this API inspire a number of third-party calendar gadgets that we can use to better plan, manage, track, and share our busy schedules.
