DOWK has been hammered many times on the 400 fora. Do a search on 'day of week' . Some of the latest versions of RPG evidently have a fairly complete set of date functions. If you're just looking for something to program, search the www for "Zeller's Congruence" . If you still need help, e-mail me at roberth@utdallas.edu and I'll help you. bobh
