 I wrote this for http://krass.com/ where I have simple event
 calendar. Examples are at http://krass.com/wiki/Current_events and
 http://krass.com/wiki/Calendar
 
 The idea was to keep the calendar as simple as possibe and leave all
 the editing and page creation to mediawiki. It doesn't require any new
 database tables or files.
 
 To use this on your mediawiki site, copy the php files into your
 extension directory and put this into your LocalSettings.php:
 
   include("extensions/Calendar.php");
 
 Then you can use the calendar on any page like this:
   
 <calendar>
 name=krass
 view=year
 </calendar>
 
 The parameters work like this:
 
 "view" 
        can be "days" days from today, "rdays" (reverse days),
        "week","month","threemonths" and "year" (default).
 "name" 
        is a name for the calendar and changes the names of the day pages.
 "format" 
        defaults to '%name_%year_%month_%day' and describes the names
        of the day pages.
 "formattitle" 
        formats the titles in today/days/week view
 "day","month","year"
        you can specify the date of the calendar, it defaults to today.
        currently this doesn't work with "view=week"
 "date" 
        this takes a php strtotime ( http:://www.php.net/strtotime )
        option and overrides the "day","month","year" option
        above. examples are:
  
        date="+1 week"
        date="next monday"
        date="+7 days"
 "weekstart"
        week starts on 1=monday ... 7=sunday. default is 1
 "skipempty" 
        skip empty days in week view
 "showempty"
        show inivitation to add entries when a day is empty, default is 1
 "weekformat"
        format of the week, days, rdays and today view.
 
        - "text" (default), simple wikitext format
        - "list" a layout that uses <dl>, <dt> and <dd> (definition
          list) tags with the 'calendar' class added to the <dl>
          tag and the calendarToday class to the span tag that
          contains the weekday title. Merged calendar
          entries are added as sub lists with the name part of the
          merged calendar as a link to the page of that
          calendar.
        - "table" a layout that uses table tags with also the name of
          merged calendars as a link to the page of those
          calendars. The 'calendar' class is added to the table tag and
          the 'calendarToday' class to the span tag that contains the
          weekday title.
 
 format & formattitle accept these substitutions:
         %name
         %day,%month,%year
         any php date() substitution prefixed with '%', like '%m','%d','%Y'
