OS X Mountain Lion Bible

Summary

The Contacts lets you manage your contacts, and it works with Mail and Calendar to make it easy to fill in and contact people listed in the Contacts. Contacts can sync with Exchange 2007 and 2010, Google, iCloud, and Yahoo accounts, as well as with LDAP and CardDAV servers.

Calendar lets you create and track appointments and to-do items, as well as invite other people to meetings via e-mail notifications. It supports .ics invitations that can be sent via e-mail; the recipient can accept the invitation either in Mail or Calendar and have a confirmation sent to the originator.

In addition to syncing invitations with others, you can set up shared calendars in Calendar. And Calendar can sync calendars with your Exchange 2007 and 2010, Google, iCloud, and Yahoo accounts, as well as via CalDAV servers such as OS X Server.

The new Reminders application is where you add and manage tasks and sync them with other computers and devices; this capability is no longer handled by Calendar. Likewise, the new Notes application is where you add and manage notes and sync them with other computers and devices; this capability is no longer handled by Mail.
