iCal Icon    About calendar standards
 

iCal uses a format called "iCalendar" to display and exchange calendar information. iCal can exchange calendar information with several applications that support the iCalendar format. iCal can also import information stored using the older "vCalendar" format.

Calendar events that you export or drag to the desktop have a file name that ends in ".ics," and vcalendar files end in ".vcs." Both types of files can be viewed on Macintosh or Windows computers by applications that understand these extensions.
