India Diwali celebrations are lighting homes, temples, markets and streets across the country as millions mark the Hindu festival of lights. This year’s festivities are taking place alongside serious air-quality concerns, especially in northern India, where seasonal weather, crop-residue burning and fireworks have contributed to hazardous pollution.
Diwali is traditionally associated with the triumph of light over darkness, good over evil and knowledge over ignorance. While firecrackers are a familiar part of the festival, the occasion also centres on prayer, family gatherings, charitable traditions, food, gifts and the lighting of small oil lamps known as diyas.
India Diwali celebrations continue amid hazardous air pollution
Delhi is experiencing particularly severe pollution during this year’s festival, with air-quality conditions described as the worst for a Diwali celebration in a decade. Mumbai has also recorded elevated pollution levels in recent weeks.
Air pollution typically worsens around Diwali because fireworks add particulate matter and other emissions to the atmosphere. In northern India, the problem is intensified by calm seasonal weather and smoke from agricultural fires. The resulting smog can affect visibility and increase health risks for people with respiratory conditions, older adults and children.
India’s Supreme Court has permitted the manufacture, sale and use of certified “green” firecrackers in Delhi and nearby areas for a limited period. These products are designed to generate 20–30% fewer emissions than conventional fireworks. However, environmental campaigners and other critics have questioned how effectively the restrictions can be enforced, particularly when fireworks may enter the capital from neighbouring states.
Why air quality remains a major festival issue
- Fireworks release smoke and fine particles into the air.
- Crop-residue burning contributes to seasonal pollution in northern India.
- Weather conditions can trap pollutants close to the ground.
- Repeated breaches of fireworks restrictions can prolong post-Diwali smog.
Despite the pollution debate, community leaders and families continue to emphasise that Diwali is much broader than fireworks. Homes are cleaned and decorated, markets fill with festive shoppers, and families prepare traditional meals and sweets.
Diwali traditions bring families and communities together
The festival takes place on the darkest night of the Hindu lunar month of Kartik, when the moon is not visible. Customs vary across India, but many households light diyas, create rangoli patterns at entrances and offer prayers to Lakshmi, the Hindu goddess associated with wealth and prosperity.
Diwali is generally observed over five days:
- Dhanteras: Many people buy gold, silver, utensils or other items believed to bring good fortune.
- Chhoti Diwali: Families light lamps and, in some areas, use fireworks.
- Main Diwali: Evening prayers, festive meals, gifts and community celebrations take place.
- The fourth day: Traditions differ by region, with some communities observing family gatherings or New Year celebrations.
- Bhai Dooj: The final day celebrates the bond between brothers and sisters.
Markets across cities such as Delhi and Mumbai are decorated with colourful lights, while shoppers purchase flowers, lanterns, sweets and household items. Potters also prepare and paint clay diyas, an important symbol of the festival.
Diwali’s meaning across religions
For many Hindus, Diwali recalls Lord Ram’s return to Ayodhya after defeating Ravan in the Ramayana. The story represents the victory of good over evil and the restoration of righteousness.
The festival period also has significance for other communities. Sikhs observe Bandi Chhor Divas, which commemorates the release of Guru Hargobind from imprisonment at Gwalior Fort. For Jains, Diwali marks Lord Mahavira’s attainment of moksha, or liberation from the cycle of rebirth.
Diwali is also celebrated by Indian communities around the world. Families and friends gather for meals, prayers, cultural events and gift exchanges, making the festival an international celebration as well as a major occasion in India.

Diwali and the symbolism of new beginnings
The festival is widely viewed as an auspicious time for new purchases and fresh starts. India’s stock exchanges traditionally hold a special one-hour trading session known as Muhurat trading, reflecting the belief that buying and selling shares during the festival can bring prosperity. This year’s session is scheduled for 8 November.
From illuminated streets and rangoli designs to prayers, sweets and family reunions, Diwali remains a festival shaped by both public celebration and personal reflection. The growing focus on air pollution may change how fireworks are used, but it has not diminished the wider cultural and spiritual importance of the occasion.
Conclusion: India Diwali celebrations balance tradition and responsibility
India Diwali celebrations continue to express hope, prosperity and the triumph of light, even as cities confront dangerous pollution levels. The festival’s enduring meaning lies not only in fireworks, but also in its diyas, prayers, family bonds and acts of renewal. The clearest takeaway is that communities can preserve Diwali traditions while supporting cleaner, safer and more responsible celebrations.
