Horā has two primary meanings in Vedic astrology. As a divisional chart (D2), it divides each rashi into two equal halves of 15° each — one half governed by the Sun (the masculine/yang half) and the other by the Moon (the feminine/yin half). It is primarily used to assess wealth and financial matters. As a time-keeping system, horā refers to planetary hours — each day is divided into 24 equal hours, each ruled by one of the seven visible planets in a fixed sequence. The planetary hour at birth or for any activity selection carries the vibration of its ruling planet.
