I don't think that calendar style is widely known in the US, aside from a handful of industries.

Here's an example. It's not a great picture, but you can see that the months are listed one above the next, each with all of its days in a horizontal row, and shifted laterally so that the days of the week line up from one month to the next.

Sadly, I don't know of a Perl module to create such calendars in HTML.
