This is actually a good topic to bring up.

$single is set to true when wp-blog-header.php returns only one post. 
There are no equivilents for saying "you're on a monthly archive page" or 
"you're on a category page." The best you can do is check heuristically 
for things like $cat or $category_name. This isn't perfect as $cat is 
often set to restrict categories shown on different pages.

What do you guys think of a set of variables like so that would be set by 
blog-header:

$on_single = $single
$on_category
$on_subcategory
$on_day
$on_month
$on_year

Any more?
