I should have stated as a restriction that my scheme is limted to a span of 273 years. And Rexx's not supporting the Julian calendar. >Lets say you have managed to get a random number between 1 and 3,652,058 by >tweaking the formula for random number, how are you planning to avoid >duplicates? > The OP didn't specify whether he wanted "sampling with replacement" or "sampling without replacement". My scheme corresponds to sampling with replacement, which realistically models a sampling of birthdays of randomly selected individuals; duplicates are possible. I haven't a good example of dates sampled without replacement; I don't doubt there are some.
