As I already used {{CURRENTDAY}} {{CURRENTMONTHNAME}}
in http://it.wikipedia.org/wiki/Template:PaginaPrincipale/Attualita
I propose to change three files in order to add two more time variables to
mediawiki environment.

See proposed changes:

mario@castrum /usr/local/mediawiki/includes$ diff MagicWord.php MagicWord.orig
51,52d50
< define("MAG_CURRENTWEEK", 35);
< define("MAG_CURRENTDOW", 36);
61,62d58
< MAG_CURRENTWEEK,
< MAG_CURRENTDOW,

mario@castrum /usr/local/mediawiki/includes$ diff Parser.php Parser.orig
1540,1541d1539
< case MAG_CURRENTDOW:
< return $wgLang->formatNum( date( 'w' ) );
1544,1545d1541
< case MAG_CURRENTWEEK:
< return $wgLang->formatNum( date( 'W' ) );

mario@castrum /usr/local/mediawiki/languages$ diff Language.php Language.orig
176,177d175
< MAG_CURRENTWEEK => array( 1, 'CURRENTWEEK' ),
< MAG_CURRENTDOW => array( 1, 'CURRENTDOW' ),
