Abstract: Vedic Astrology covers almost all important phases of our life. If we understand the concepts and combinations of planets, then it can produce extremely accurate results - certainly in Gender prediction. Based on this, the objective was formed: To know the accuracy of predicting the gender of baby through Vedic Horoscopes of parents with the help of 1. Brihat Jatak translated into English by N. Chidambaram Iyer, 1885 June 2, and 2. Fourth Reader- Marriage, Married Life and Children by Krishnamurti Padhathi, 1989. The collected data of 100 children (58 Male and 42 Female babies) already born with parents Vedic horoscopes transformed into numerical format was put for statistical tests under Data Mining techniques. It is the process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems. The analysis methods used in the process shows that, the pattern of prediction was true for 25 male and 15 female babies as per True positive (Male baby predicted as Male) and True negative (Female baby predicted as Female) based on parents Lagna. Further the data was examined based on present absent criteria of planets in respective houses, which resulted in 29 male recorded in True positive and 9 female recorded in True negative. Then the left out data was tested based on proportion of each house filling criteria, which resulted in 14 female babies and recorded in True negative. The undecided data was 4 in male gender under True positive and 3 in female gender under True negative, which resulted in no planets in respective houses. Remaining 1 data was predicted as Male for Female gender which is under False Negative. The overall success ratio was recorded as 92% in which 54% was Male and 38% was Female babies. The results from the proportion tests based on present absent criteria of planet in respective houses showed that, first child from eleventh house (opposite to Fifth House) of father horoscope and second child from seventh house in both father and mother horoscope was significant for gender prediction of baby with P Value¬= 0.002, 0.003 and 0.003 respectively.
