Niṣekādhikāra (निषेकाधिकार) (lit. “regarding impregnation”) is the name of the fifth chapter of the Karmaprakāśa—one of the earliest preserved Sanskrit works on Perso-Arabic (Tājika) astrology authored by Samarasiṃha in the 13th century.— Chapter 5 (niṣekādhikāra) sets out the doctrine generally known in western literature as the trutine of Hermes, positing an astrological correlation between the times of conception and birth—the ascendant degree in one being the ecliptical longitude of the moon in the other, and vice versa. This in turn makes it possible to adjust an approximate ascendant and its concomitant time of birth. The average duration of a normal pregnancy is assumed to be 273 days or exactly ten sidereal months, with a maximum deviation of a fortnight either way. The antecedents of this doctrine, ascribed by Hellenistic writers to Petosiris, are quite ancient: the average value of 273⅓ days for the gestational period is known from Babylonian astrological sources

context information

Jyotisha (ज्योतिष, jyotiṣa or jyotish) refers to ‘astronomy’ or “Vedic astrology” and represents the fifth of the six Vedangas (additional sciences to be studied along with the Vedas). Jyotisha concerns itself with the study and prediction of the movements of celestial bodies, in order to calculate the auspicious time for rituals and ceremonies.
