Release history[]

ICal 4.0 OS X 1

iCal 5 from Mac OS X Lion (10.7)

Apple licensed the "iCal" name from Brown Bear Software, who used it for their own unrelated iCal application since 1997.[1]

Apple's first release of iCal was a free download for Mac OS X 10.2 on September 10, 2002. With the release of Mac OS X 10.3, it was bundled with the operating system as iCal 1.5. Version 2 of iCal was released as part of Mac OS X 10.4, Version 3 as part of Mac OS X 10.5, Version 4 as part of Mac OS X 10.6, and Version 5 as part of Mac OS X 10.7. With 10.8, it was renamed "Calendar".

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's U.S. headquarters in Cupertino.[2]
