VCalendar

From Free net encyclopedia

Template:Lowercase

vCalendar is an older standard exchange format for calendar data promulgated by the Internet Mail Consortium (IMC). iCalendar is a newer standard (RFC 2445) for calendar data, heavily based on vCalendar.


Here is an example of information in vCalendar format: 

BEGIN:VCALENDAR
VERSION:1.0
BEGIN:VEVENT
CATEGORIES:MEETING
STATUS:TENTATIVE
DTSTART:19960401T033000Z
DTEND:19960401T043000Z
SUMMARY:Your Proposal Review
DESCRIPTION:Steve and John to review newest proposal material
CLASS:PRIVATE
END:VEVENT
END:VCALENDAR

Note that the version number in the above example is 1.0. iCalendar is version 2.0 of the vCalendar specification. Here is an example of information in an iCalendar format:
