I am taking the algorithms out of PRACTICAL ASTRONOMY WITH YOUR CALCULATOR and coding them into computer programs on my PC. But I need a reliable method of knowing when daylight savings starts and ends. Anyone know such a method, i.e. 3rd Saturday in April or similiar? BTW, these are being coded in the APL language. many thanks, joec@morgan.com
