Calendar makes it easy to stay on schedule. You can view individual calendars, or several calendars
at once. You can view your events by day, by month, or in a list. You can search the titles, invitees,
locations, and notes of events. If you enter birthdays for your contacts, you can view those
birthdays in Calendar.
You can also make, edit, or cancel events on iPhone, and sync them back to your computer. You
can subscribe to Google, Yahoo!, or iCal calendars. If you have a Microsoft Exchange or iCloud
account, you can receive and respond to meeting invitations.
