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?
ISO 8601: Monday=1, Sunday=7 C: Sunday=0, Saturday=6 So there is at least agreement that Moday to Saturday have the numbers 1-6, only the Sunday can choose to be the first or last day of the week. ISO 8601 establishes a week numbering scheme that is used at least in many European countries widely for industrial planning (and more recently also for naming weekly computer logfiles). Today week 40 of 2000 started. The ISO week numbering scheme starts the week on Monday and since you decided anyway to start at 1, then I would suggest the ISO convention is the way to go. For details, please read http://www.cl.cam.ac.uk/~mgk25/iso-time.html There is no real "Right Thing" anyway, because weeks and week days are a very arbitrary cultural convention that seems not to be based on any more fundamental reasons.
