You can create multiple calendars to organize events. For example, you can have a personal calendar as well as a calendar for the family, bridge club, soccer team, and the like. You can view multiple calendars, either one at a time or in combination, enabling you to coordinate schedules and stay on top of friends' and family plans. If you want to view a calendar that doesn't appear on your Calendars list, you need to subscribe to that calendar. Another way to view other calendars is to subscribe to calendars that family and friends share with you. You receive e-mail when others invite you to subscribe to a calendar.
