Deepavali falls on Sunday, 8 November 2026 in Tamil Nadu, the date the state used when it announced festival bus arrangements on 13 October. Because the festival lands on a Sunday, government offices and banks get no extra day off. The question most Chennai households are now asking is when they may burst crackers, and as of 18 October the state had not announced the 2026 time slots.
Tamil Nadu normally issues its order a few weeks before the festival. Last year the announcement came on 15 October 2025, and in recent years the windows have been the same: 6 am to 7 am and 7 pm to 8 pm on Deepavali day. Until the 2026 order is published, treat those timings as the likely pattern, not as this year’s confirmed rule.
Why Tamil Nadu gets two hours, and why one is at dawn
The limit comes from the Supreme Court. In October 2018, while hearing the long-running Arjun Gopal case on air pollution, the court restricted the hours for bursting crackers across the country. On 30 October 2018 it modified the order for Tamil Nadu, Puducherry and other southern states, allowing a total of two hours in the day and leaving the state government to decide exactly when.
Tamil Nadu chose to split the two hours between early morning and evening. That suits the way the festival is kept here: many families take the oil bath and wear new clothes before sunrise, and the first round of crackers follows soon after. The evening hour covers the sparklers, flowerpots and rockets that children wait all day for.
The rules of recent years
The Tamil Nadu Pollution Control Board’s 2024 guideline, reported by DT Next, the state’s 2025 release reported by ETV Bharat, and Chennai police advisories set out a fairly stable list of do’s and don’ts. Expect most of these to be repeated:
- Time: only 6 am to 7 am and 7 pm to 8 pm on the festival day.
- Type: green crackers, which are designed to make less noise and smoke.
- No joined crackers: the 2025 release warned against long series or chain crackers because of the noise they make. TNPCB has also asked people to avoid continuous bursting.
- Where not to burst: near hospitals, educational institutions and places of worship, and close to huts or anything easily set alight.
- Community celebrations: TNPCB says collective bursting needs prior permission from the district administration or local body and should be organised through residents’ welfare associations.
- Noise: the Chennai police guidelines for 2024 reminded residents that crackers louder than 125 decibels at four metres are prohibited.
- Roads and vehicles: police have asked people to avoid busy roads, parked vehicles and fuel stations, and not to throw lit crackers towards passers-by.
In 2023 the Chennai police said bursting outside the permitted hours would attract a fine. The exact penalty and enforcement plan for 2026 will come with this year’s notification, so watch for announcements from the Greater Chennai Police and TNPCB.
Buying crackers in Chennai this year
The biggest temporary cracker market in the city is usually the fair at Island Grounds, and this year its layout is in dispute. The Chennai Fire Works Dealers’ Welfare Association, which has run the fair through the tender process since 2014, told the Madras High Court that construction work and the shifting of an MTC bus stand to the grounds had shrunk its space. The government advocate said a tender for allotting cracker shops would be floated soon, and the judge adjourned the case to 13 October, DT Next reported. Check local news for the final dates and layout before heading there.
Wherever you buy, stick to licensed shops that display their licence, and look for the green-cracker logo and QR code on boxes. Avoid unlabelled or country-made products, be wary of online “doorstep delivery” offers, and never store large quantities at home.
Being a good neighbour on the day
- Keep a bucket of water and a bucket of sand ready before anyone lights a fuse.
- Children should burst crackers only with an adult beside them, in cotton clothes, away from the house entrance.
- Elderly residents, babies, people with asthma and pets suffer most from noise and smoke. A short word with neighbours about timings goes a long way in apartment complexes.
- Rain is likely. The northeast monsoon set in over Tamil Nadu on 15 October, so damp crackers that refuse to light should be soaked in water and set aside, not relit or inspected closely.
There is also a quieter tradition close to the city. Villagers around the Vedanthangal bird sanctuary in Chengalpattu district have long celebrated without loud crackers, because the festival coincides with the arrival of nesting birds.
