You can make Outlook open automatically when you click a link to send e-mail (sometimes called a 'mailto' link) in a document or on a Web page. Similarly, you can make events and contacts open in Outlook when you open them from the Finder or the desktop.
Manage all your events in Calendar, even if they’re in different accounts like iCloud or Google.
Create separate calendars for different areas of your life. Then, spot your work, family, or personal events with a quick glance.
Quickly set up your own events and send Calendar invitations to friends and coworkers.
All the information you need about an event at your fingertips. When you add the location of your event—like the name of a restaurant—Calendar fills in the address, shows you a map and the weather, and lets you know when it’s time to leave.
