Overview
- Drik Panchang says the Amavasya tithi runs from 3:44 pm on Oct. 20 to 5:54 pm on Oct. 21, creating a two-date window for Diwali.
- Several panchangs list Lakshmi Puja on Monday, Oct. 20, with a commonly cited muhurat of 7:08–8:18 pm.
- Hindustan Times reports India will mark Diwali on Oct. 21, while U.S. cities are advised to perform Lakshmi Puja on Oct. 20 with local muhurats.
- U.S. timings vary by source and time zone: Drik Panchang and Pratyangira Siddhi publish differing evening windows across Eastern, Central, Mountain and Pacific zones.
- One Times Now interpretation applies a sunset rule, suggesting Oct. 21 where sunset is at or before 5:30 pm and Oct. 20 where it is later, as calendars continue to list Dhanteras (Oct. 18), Choti Diwali (Oct. 19) and Bhai Dooj (Oct. 23).
