If you still have the calendar wizard from the previous version of Word, it
should still work with Word 2007. I just used it to crank out a 9/2008 -
9/2009 portrait calendar, and it worked just fine.
Barring that... If you click Office button - New, and type "calendar" into
the search space at the top of the New Document dialog--then press
Enter--Word should search online (assuming you haven't disabled online
searching) for different calendar templates. There are a variety of
different styles--some landscape and some portrait. Most of the portrait
ones have additional elements you might not want (like space for a picture).
However, there is a portrait one for 2008 (2008 business calendar) that has
two months per page.
