The calculation for Nine Star Ki numbers and for KUA numbers are identical for Males, and so they are equivalent. However, Nine Star Ki astrology uses the same calculation for Females as it does for Males, so, a Female’s Nine Star Ki number would be different than her KUA number. For most uses, it is best to go by the standard KUA calculation, particularly when reviewing beneficial or problematic directions, elements etc. The advice on moving, renovations and on the Nine Ki Chart available under the Advice menu are based on Nine Star Ki astrology, so, it may be beneficial for women to calculate their KUA number as a Male before running these reports. This will ensure that the standard Nine Star Ki calculation was used in the analysis of these charts.
