Validity of the Chinese lunar calendar to predict gender

Abstract

The purpose of this study was to examine the validity of gender prediction using the Chinese lunar calendar. Analyses of data from 1,005 births were used to evaluate if gender at birth could be predicted using maternal age at conception and the month in which the woman conceives, as proposed in the Chinese lunar calendar. The study was a retrospective, nonexperimental design with quantitative analyses. Data were interpreted using chi-square statistic. Findings from this research supported the results of previously performed studies used to evaluate the use of the Chinese lunar calendar to predict gender that there is no correlation between gender predicted using the Chinese lunar calendar and actual gender at birth.
