ICal
From ICHKWiki
iCal is a personal calendar application that is made by Apple. It runs on the Mac OS X operating system. iCal was the first calendar application for Mac OS X to offer support for multiple calendars and the ability to publish/subscribe calendars to WebDAV server. This iCal is very useful when you want to save a specific date.
In iCal you can write down things you can not remember like if you got to go to the dentist or you need to remember someones birthday. For staff, it could be for meetings or when to do presentations for work.
iCal development is quite different from other apple applications because it was designed independently by a small French team working "secretly" in Paris, led by Jean-Marie Hullot, a friend of Steve Jobs. [1]
Did you know, that the iCal icon on your Dock actually shows the real time all the time? [2]
