I haven't been keeping up with the nctml mailing list recently (so many messages! and my own job is quite busy lately. I had hoped to write something clarifying Brouwer and intuitionism and how little the subject has to do with the "constructivism" discussed here, but by the time I get to it, the topic will be long forgotten.)  so I apologize if this reference has been cited already.
Anyway, on the subject of calendars and mathematics, my friend Ilan Vardi had a chapter in his book Mathematica Recreations (later retitled something like "Computer recreations in mathematics"  to appeal to an audience a bit broader than Mathematica users), published by Addison Wesley on "mixed radix systems" which in effect, calendars are. He includes (if I remember correctly) information on Indian, Mayan, Julian/Gregorian, Jewish, Islamic and French Revolutionary calendars (though he omits the Italian Fascist calendar  does anyone know the structure of it? Did they just rename the months?) and puts them in an interesting mathematical framework.
