A group calendar allows you to see multiple calendars at once. A group calendar, for example, is handy when planning a team meeting because it shows the availability of team members and conference spaces. Calendars are a great way to keep deadlines, birthdays, and special events all in one place. You can also share calendars with friends, family and coworkers. The best part is that you won't have to switch between multiple calendars. Users can access their calendar right on the Group Calendars website and see all events for the entire group in one place.
