This module displays date-based Views in a calendar layout, supporting year, month, week, and day views with built-in navigation. It works with any date field—such as Drupal core's date, date range fields, created/updated timestamps or date_recur—configured in a View.
Taxonomy_List.module is for displaying the terms (and optionally nodes) under categories (taxonomy terms) and descriptions. User can select the number of terms to display in each row, and assign the HTML attributes to the display cell, image, and the description text.
The directory module presents a very simple and lightweight hierarchical 'directory-like' view (conceptually similar to DMOZ, Yahoo, etc.) of nodes that have been assigned to one or more designated taxonomy 'vocabularies' (depending on module configuration). This allows users to drill down on selected content on your Drupal site.
If you have a site with taxonomies already in place, and/or you are not using the category module, this module may be a simpler approach to hierarchical navigation - just drop it in, configure, and go.
