Well, since we're not using it for long-term historical ranges -- and we'll need to be able to advance/reverse it a couple of days no matter the algorithm, then I say let's go with whatever is easiest for hans to read ;-)
I think Umm al-Qura algorithm is more tested and is the one officially used in Saudi Arabia, but I can't find any technical details about it, though Arabeyes's ITL implements it
How did you implement it without the technical details? I guess I'm not quite understanding... Can you find it and pass it alon?
and is giving me correct results so far (unlike the Hijra algorithm). EMACS one seems to be widely used too, but its ITL implementation gives me incorrect dates some times
How incorrect? I have a friend who specializes in Islamic astronomy and I'll ask him about this as well. Best wishes Idris -- Professor Idris Samawi Hamid, Editor-in-Chief International Journal of Shi`i Studies Department of Philosophy Colorado State University Fort Collins, CO 80523
