I just heard from Roberto Brum from Brazil who found a way to simplify my Formula #19. This is a formula that you can use to find the last Friday of any month (or any other weekday). I liked his approach so I put it side by side with my original formula for testing. For the most part they worked exactly the same, and the few differences I found were due to my own errors in the original formula. So, not only is it more elegant, but it is also more accurate. So I have now posted Roberto’s formula on the page above. Many thanks, Roberto!
