Calendar, previously known as iCal before the release of OS X Mountain Lion, is a personal calendar application made by Apple Inc. that runs on both the OS X desktop operating system and iOS mobile operating system, with online integration using iCloud.

iCal was the first calendar application for OS X to offer support for multiple calendars and the ability to intermittently publish/subscribe to calendars on WebDAV servers.

Originally released as a free download for Mac OS X v10.2 on September 10, 2002, it was bundled with the operating system as iCal 1.5 with the release of Mac OS X v10.3. Version 2 of iCal was released as part of Mac OS X v10.4, Version 3 as part of Mac OS X v10.5, Version 4 as part of Mac OS X v10.6, Version 5 as part of Mac OS X v10.7, and Version 6 as part of OS X v10.8.

Apple licensed the iCal name from Brown Bear Software, who have used it for their iCal application since 1997.[1] With the release of OS X v10.8 in July 2012, iCal is called Calendar, similar to the iOS version.

iCal development is quite different from other Apple software because it was designed independently by a small French team working "secretly" in Paris, led by Jean-Marie Hullot, a friend of Steve Jobs. iCal's development has since been transferred to Apple US headquarters in Cupertino.[2]

Features[edit]

  • It tracks events and appointments, allows multiple calendar views (such as calendars for "home", "work", and other calendars you create) to quickly identify conflicts and free time.
  • It is integrated with iCloud, so calendars can be shared and synced with other devices, such as PCs, iPhones, and iPod touch, over the internet. You can also share calendars via the WebDAV protocol. Google now supports WebDAV for Google Calendar making iCal easily configurable.
  • Users can subscribe to other calendars so they can keep up with friends and colleagues, and other things such as athletic schedules and television programs.
  • iCal allows notification of upcoming events either on screen, by email, SMS, or Pager.
  • iCal supports the use of the iCalendar format [VERSION:2.0]. It does not support the older vCalendar 1.0 format. [VERSION:1.0]

New in version 3[edit]

  • Setting to let iCal set auto-alarms for each event created.
  • Redesigned user interface
  • Inline event editing
  • Ability to turn off alarms for all events
  • Use a CalDAV(WebDAV) account to store and keep calendars in sync on a CalDAV server.
  • The date on the icon in the Dock displays the current date all the time. (Until version 3, iCal's icon displayed July 17—the date iCal premiered in 2002 at the Macworld Expo—by default until the program was run.[3])

New in version 4[edit]

  • Microsoft Exchange Server 2007 support[4]
  • Refined user interface (particularly for multiple events management)
  • Automatic setup for Yahoo/Google Mail/Gmail calendars. Events are synced and downloaded from your account.

New in version 5[edit]

New[edit]

  • Microsoft Exchange Server 2010 support[5]
  • New skeuomorphic skin similar to Calendar for iPad.[6]
  • Full-screen support[5]
  • Agenda list and mini-month display added to Day view[5]
  • Quick Add for adding events[5]
  • Heat map to indicate the number of activities per day[5]

Removed[edit]

  • Dedicated calendar pane (now just a pop-up menu under the "Calendars" button)
  • Details pane on the right hand side
  • Mini month display in non-Day views
  • Ability to select/highlight days in Month view

New in version 6[edit]

New[edit]

  • All calendars accessible in sidebar[5]
  • Search suggestions when searching for events[5]
  • Creates a search token displaying a list of events[5]
  • New date picker[5]
  • Event notifications in Notification Center[5]
  • Add attachments to iCloud Calendar items[7]

Removed[edit]

  • Ability to select variable snooze durations. Only 15 minute snooze available.[8]

Bugs[edit]

iCal supports time zones, i.e.: if the function is enabled, and the computer’s time zone changes, all the events in iCal are shifted to compensate for the time zone difference. The bug is that this problem also occurs when the time zone function is disabled, therefore whenever the computer’s time zone changes, all the events in iCal shift as well. As of today, there is still no fix for this bug and this bug has carried over through Mac OS 10.4 (Tiger), 10.5 (Leopard), 10.6 (Snow Leopard) and 10.7 (Lion).[9]

Alert data loss always occurs when alarm alert windows currently being displayed disappear due to reboots, system crashes, or race conditions, because they never reappear.[10]

Although not strictly a bug, full time zone support has never been implemented in the Calendar app. There is no way of specifying events different timezones for start and end time, even though the underlying RFC 6868 iCalendar specification does allow this. This is a feature necessary to e.g. sensibly plan cross-timezone flights or trains.
