Shubha Hora divides the time from sunrise to sunset and from sunset to the next sunrise into equal segments called horas (planetary hours). Each hora is ruled by a planet in a fixed repeating order. The first hora after sunrise begins with the weekday lord—the planet that rules that day. Traditionally, horas of Jupiter, Sun, Venus, and Mercury are favoured for auspicious beginnings; the Moon is mixed; Mars and Saturn horas are chosen more carefully. Boundaries depend on real sunrise and sunset at your location, so hora times change with place, date, and timezone. Key points: • Day and night: 12 horas in the daytime arc and 12 in the night arc between one sunrise and the next (24 horas total). • Day ruler: The weekday determines which planet opens the daytime hora sequence at sunrise. • Benefic horas: Jupiter, Sun, Venus, and Mercury are widely used for starts; Moon is variable; Mars and Saturn are used with caution. • Local calculation: Longitude and timezone shift the cut-off times; use values computed for your coordinates.
