Re: week starts at Sunday or Monday??

so my question is.... now that I decided that days are niumbere 1 to 7, what is day 1 ??? is it Sunday, or Monday? what is the Right Thing to do?

Your choice is ok. One observation to add is about numbering/enumerating/counting in general: 1st, 2nd, 3rd, ... well - I've never heard about "the 0-st". Enumerating starting with zero seems to have come in vogue with C, due to the simpler address calculation (saves some micro seconds?). Whether week starts with Monday or Sunday depends on the culture; this is independent of any number assigned to it. Regards, Janis
