Designed for 8.5" x 11" paper (landscape orientation), the calendar is easily printable. For best printed results, print it double-sided in color on bright white light card stock or 24-lb paper with a spiral or comb (GBC) binding and punch a hole for hanging; many local printing shops (Staples, Kinkos, etc.) offer binding services. Containing some of the best APOD images of 2012, the calendar makes a great inexpensive holiday present!
Since the calendar is in PDF, it can be viewed on devices such as the Kindle and many ereaders.
The last page of the PDF appears upside-down; this is deliberate. When printed, this page serves as the back cover of the calendar and allows one to see thumbnails of all the images in the calendar in the correct orientation (in relation to the front cover).
Happy holidays!
