Date/Calendar
Last modified: June 26, 2009 - 07:45
There are several modules that work together to handle dates and calendaring. They include a Date API, a Date module to create CCK date fields that can be added to any content type, and a Calendar module that works with the Views module to display dates in a calendar.
There's some very helpful setup info for Calendar for 6.x here: http://drupal.org/node/326061#comment-1077193
