Terrific daily challenge
I love this product and buy it every year and get some for xmas presents for friends. It is daily fun that I look forward to and challenges you more and more as the days move to Sat/Sun. Highly recommended!

Great Puzzles
These are excellent puzzles ready to be worked on a daily basis. I've given this calendar to my father in law for many years, and he loves having it around. He likes to work them while he has his morning coffee.

Compilation of NYT Crossword reprints into a page-a-day calendar
This page-a-day desk calendar features 313 consecutive New York Times daily crossword puzzles originally printed between May 11, 2004 and June 1, 2005. This series aligns with the normal Monday to Saturday progression of difficulty. Saturdays and Sundays share a calendar page and feature a Saturday puzzle.
The puzzle grids measure about 3" x 3" on the page, while each full page measures about 6" x 5". The lower right corner even features a few square inches of blank space for use as an actual desk calendar. The tear-off pages offer portability - I often keep a few pages in my planner for use in waiting rooms, train rides, etc.
The 2007 calendar merited criticism for reusing the same puzzles as the 2006 one, but this 2008 edition clearly states on the box that these are not those same puzzles.
