I am just starting some research on this topic and wondered if any of you have any pointers to any useful reference material (probably old books I suspect)
Cheers
Andy

Hi Andy,
there are a few references in early Model Engineer to perpetual calendars including articles on how to construct one (e.g. Geo Gentry Vol 61 issues 1513, 1520, and 1542)
