Keep track of your busy schedule with iCal. Create separate calendars – one for home, another for school, a third for work, and so on. See all your calendars in a single window or choose to see only the calendars you want. iCal lets you create invitations using contact information from your Address Book, update your guest list, keep track of responses, and receive the latest status information. When you or another Mac user receives an iCal invitation via Mail, it’s automatically added to iCal.
