Deepavali / Diwali
The festival of lights. In Karnataka the principal day is Naraka Chaturdashi, with the pre-dawn oil bath in the morning and Lakshmi Puja in the evening.
How the date is set: In Karnataka the principal day is Naraka Chaturdashi — the Krishna Chaturdashi of the Amanta Ashvina month — with the pre-dawn oil bath and Lakshmi Puja that evening.
Regional note: North Indian calendars centre the festival on the Kartika Amavasya Lakshmi Puja instead. The Amavasya tithi runs from 10:51 on 8 November to 11:32 on 9 November, so both traditions converge on 8 November in 2026.
