Dharmaśāstra Astronomical Determination (Nirṇaya)
Authentic Classical RuleScriptural Injunction:
“Observed on Ashvina/Kartika Amavasya overlapping Pradosha Kala. When Amavasya covers Pradosha on two consecutive evenings, the second evening is selected as authoritative.”
No classical authority is recorded for this determination in our catalogue.
Kāla Vyāpti Principle: Vedic festivals are not determined solely by Gregorian dates or standard civil calendar days — the tithi or nakshatra must prevail during its designated Kāla (time portion of the solar day).
For Diwali / Deepavali (Lakshmi Puja), worship and vrata rituals are specifically anchored to the Pradosha window.
