7 April 2000 Panchang -

What a panchang does first is fix the celestial actors: the tithi (lunar day), the nakshatra (lunar mansion), the yoga and karana (finer lunar- solar combinations), and the positions of the sun and moon that determine lagna-related guidance. Each element carries an interpretive valence. Tithis can favor beginnings or closures; nakshatras lend temperament; yogas and karanas refine timing; the weekday colors expectations. Together they compose a temporal grammar that people consult when they want to align human action with perceived cosmic favor.
