One interesting bit of reading about this stuff comes from the nice 
folks at
http://www.wundermoosen.com

(in fact, I see they've put out some more calendar white papers, 
including "How we figured out the Viking calendar.")

Look under Calendar X for the Viking calendar paper, "The Mayan 
Calendar" and some others.  

The paper I was thinking of when I started this is around here 
somewhere, but I don't immediately see it on the site.  It was referred 
to by (shipped with?) Calendar2000.  It includes a good view of when 
various countries switched from Julian to Gregorian (and in at least one 
case switched back and switched again).
