My purpose in sharing knowledge of the lunation birthday concept is to help make this astrological tool more widely understood and available. I consider it to be the most intimate astrological significator at our disposal, revelatory of important underlining psychological attributes not revealed by any other configuration in the chart. This knowledge is of special interest to the person for whom such a delineation is made. However, through this very specific astrological lens there is a much wider span of knowledge to be gained through examining the lives of well-known historical figures. For those readers interested in doing exactly that, Michael Meyer's Khaldea.com chart gallery makes it extremely easy to do so since all charts in the chart gallery indicate exactly what lunation type that individual is. The information is to be found in the "Gestalt view" box directly below the birth-chart displayed.
APPROXIMATE: Quickly Find a Lunation Birthday (ONE OF 8 SECTORS ONLY).
EXACT: iPhone owners can download this handy app for determining the exact Sun/Moon angle at birth. The app also tracks upcoming lunation birthdays (Phase Day).
EXACT: Astroseek.com offers free, online calculation of what they term "fertility days" based on the work of Dr. Eugene Jonas. Although the service is aimed at determining when a woman is fertile, according to the phase of the Moon at her birth, the same calculation refers to the more general, genderless notion of the lunation birthday. Simply input birth data for either male or female into their "Fertility Days Calculator".
EXACT: To MANUALLY determine a person's exact lunation birthday, start with the Sun's zodiacal position in the birth-chart, then proceed counterclockwise to the Moon's position, calculating the number of degrees (and minutes) between the two luminaries.
