You can find the Google Calendar Labs under the gear-shaped drop-down at the top right of your calendar page. These are experimental additions to Calendar that have not been incorporated into the main product, but which may prove incredibly useful to you and your business. For example, you can set the calendar to hide the morning and night, since you won't be holding meetings then. Another great Lab allows you to attach documents to meetings and events to make sure that everyone gets the documents that they need. Finally, the ‘next meeting’ add-on let’s you know how far away your next event is, and what the details are.
