The Extraction of Determinations for Lunar Days

...the earlier or the later day should be accepted. When a ritual timing spans across two days, the annual Jyeshtha Vrata a ritual observance, often dedicated to Jyeshtha Gauri, performed during the bright half of the month must be performed on the eighth lunar day original: Ashtami alone. However, the Southerners referring to practitioners of the Deccan or South Indian traditions perform the worship only when the moon is in the Jyeshtha constellation the 18th lunar mansion. Regarding this, the scholar Madhava Madhava Acharya, a 14th-century authority on Vedic law states that an eighth lunar day falling on a Sunday original: Bhanuvara combined with the Jyeshtha constellation is considered exceedingly auspicious.
