The raw data wasn't very usable, so I formatted it such that four years dates at a time would fit on a printed page. In the outside margin of each page I specified the dates covered. The position of this indicator is an indicator of itself - at the beginning of the booklet it is near the top of the page, but by the last page it has moved nearly to the bottom.
To complete the package I wrote up the results of some calendar research I had done, added a colophon and the Java code, and turned the whole thing into a PDF.
