iCal makes it easy to keep track of your busy schedule. You can Create as many separate calendars as you need — one for home, another for school, a third for work, and so on. You can see all your calendars in a single window or choose to see only the calendars you want.
With iCal, you can invite friends and Family to Events. iCal lets you create invitations using contact information from your Address Book, update your guest list, keep track of attendee responses, and receive the latest status information. A centralized notification box keeps all your invitations and responses in one easy-to-access location so you can manage events in iCal instead of your busy email inbox. And when you or another Mac user receives an iCal invitation in Mail, it’s automatically added to iCal.
Thanks to Spotlight, it’s easy to find information in Mail, iCal, and Address Book. Within the applications, a search sorts through everything — all fields in an email, all information on a card or Appointment — so you find every possible match. If you’re not using the applications, you can still find messages, contacts, and appointments by using Spotlight search in the menu bar. Start typing a search term and Spotlight returns the related items immediately.
