Hora is a unit of time in Vedic astrology, roughly equivalent to one hour. It is derived from ancient Indian astrology texts and is used to determine auspicious and inauspicious periods throughout the day for various activities.
Hora timing is calculated based on the sunrise time of the day. The time between sunrise and sunset is divided into 12 equal parts, with each part representing one Hora. The first Hora after sunrise is ruled by the Sun, followed by the Moon, and then the other five visible planets in a specific order.
Horai timing is significant in astrology for determining auspicious timings for activities such as starting a new venture, conducting business, or performing rituals. Each Hora is associated with a planetary ruler, and the nature of the planet influences the quality of time and the types of activities suitable during that period.
