Unfortunately for my proof, the number : of days in any 400 year interval on the Gregorian calendar *is* a : multiple of 7, and thus some other form of analysis is required : to determine what the distribution of the days of the week that : the 13th of a month fall on is. You're almost there. The number of 13th's in a period is 12*400, which is not a multiple of 7, so they can not be equidistributed among days of the week. Beyond that, it's a simple matter to count them. -- gil
