Diwali 2025, the Hindu festival of lights, was celebrated across India on October 20. The five-day festival began on October 18 (Dhanteras) and continued until October 23 (Bhai Dooj). Key celebrations included PM Modi's Diwali with Navy personnel on INS Vikrant, President Murmu's Kerala visit, and festivities in temples, markets, and homes across the country. However, the celebrations were marred by severe air pollution in Delhi-NCR and several northern Indian cities. Multiple states including Delhi, Haryana, and Rajasthan imposed restrictions on sale and use of firecrackers, though enforcement remained weak.
