I haven't tried it. I took the Old Wive's Tale quiz and it said I was having a girl but some of the questions are really silly. Like the pillow to the north or south. My pillow is to the East. How do I answer that question? Can't. And like, the shape of my belly....oh I don't know that one I barely have a belly lol. So I could not take advantage of that quiz even though it is just a quiz. But, I did it just for fun. I'll have to try the Chinese calendar.
