Sarvartha Siddhi Yoga is an auspicious combination yoga — it isn't one of the panchang's 27 nitya yogas (which are based on Sun-Moon longitude). It forms when a specific weekday matches a specific nakshatra. From "Sarva" (all) + "Artha" (purpose/goal) + "Siddhi" (success): "the yoga granting success in all endeavours." This isn't a single rare yoga — it recurs many times a month (per some sources, 8-12 times), making it a practical, everyday muhurat option for small decisions. The exact weekday-nakshatra pairing table varies by source — this is the most important thing to note about this page, detailed below.
