One of the exercises I set my Prolog students is to write a program that given any date in the current year computes the day on which it fell, e.g. this year ?- day(1,january,sunday). is true. (See note 1 below for Prolog people). To make a supplementary exercise I would be interested to know about any other calendars interestingly different from our own (the Gregorian, I think). Can anyone email me about, say, the Muslim calendar or the French decimal calendar of 1789? 1. Mode of day/3 is day(+,+,?). It is an interesting exercise to write it in mode day(?,?,?) so it will backtrack through all the Mondays or whatever, but I can't be bothered!! -- ============================================================================== From: Ken Johnson Address: AI Applications Institute, The University, EDINBURGH, Scotland Phone: 031-225 4464 ext 212 Email: k.johnson@ed.ac.uk Quotation: I've had a rotten day at work so far.
