Why doesn't URwrite work for a component?

Question

1C-Bitrix

In .htaccess

<IfModule mod_rewrite.c>
....
  RewriteRule ^/calendar/([0-9]+)/([0-9]+)/$ ?year=$1&month=$2
</IfModule>

In urlrewrite_edit.php

array(
    "CONDITION" => "#^/calendar//calendar/([0-9]+)/([0-9]+)/#",
    "RULE" => "YEAR=\$1&MONTH=\$2",
    "ID" => "bitrix:news.calendar",
    "PATH" => "/calendar/index.php",
  ),
