Hi, I'm a bit confused about the eight characters birth chart I got from the personalised free report(from this website), because some of the characters produced are inconsistent with the eight characters of the FourPillar software. I know I'm not supposed to give out all the details of my birthdate etc, but I don't want it analysed, I just want to know why the characters are different and which one is more accurate. My date of birth is Sept 7th, 1981. Hour of birth is 8:30am. From this website, I got: 1st Pillar: xin you 2nd Pillar: ding you 3rd Pillar: wu zi 4th Pillar: bing chen From the FourPillar Software: 1st Pillar: xin you 2nd Pillar: bing shen 3rd Pillar: wu zi 4th Pillar: bing chen Why is the 2nd Pillar(month) different?
