Is the Supreme Court's 8-10 pm window the rule everywhere in India?

It is the national default, but states can and do set narrower or differently timed windows within the NGT's two-hour ceiling. Always check your state's current notification rather than assuming the national default applies unchanged.

Who decides if my city gets a total ban instead of a window?

The National Green Tribunal's 2020 orders trigger a total ban in cities where air quality is "poor" or worse for that festival season, based on that season's measurements, not a fixed list of cities.

Does buying green crackers guarantee I can burst them anywhere?

No. Green certification is necessary but not sufficient. You still need to burst within whichever timing window your state or city has notified for that year, and inside any additional restrictions like Delhi's periodic total bans.

Where is the one place I should check before Diwali each year?

Your state pollution control board's official notification, or your local police's festival-season advisory. Both are reissued annually and are the only reliable source for that year's exact rule.

Cracker Rules and Timings: State-by-State Guide

Why no per-state cracker ban list stays accurate: the SC/NGT national floor, how states like Delhi and Tamil Nadu layer their own notifications, and what to check for 2026.

Cracker rules and timings, state by state, always work in two layers: a national floor that applies everywhere, and a state or city notification that can tighten it further. No single fixed list of "what each state allows" stays accurate for long, because states reissue their notifications every festival season. What does stay stable is the framework underneath, and that is what this guide sets out.

Layer One: The Supreme Court's National Floor

The Supreme Court of India, by judgment dated 23 October 2018 in Arjun Gopal v Union of India (Writ Petition (Civil) No. 728 of 2015), restricted manufacture and sale nationwide to green crackers and other reduced-emission types, banning conventional high-pollution categories. The same order fixed a default bursting window of 8:00 pm to 10:00 pm on Diwali and similar festivals such as Gurpurab, and 11:55 pm to 12:30 am on Christmas Eve and New Year's Eve. It also directs PESO, the Petroleum and Explosives Safety Organisation, to ensure only crackers within the permitted noise limits reach the market. In November 2023, the Supreme Court clarified that these directions apply across all states, not only Delhi-NCR.

Layer Two: The NGT's Air-Quality Trigger

The National Green Tribunal, by orders dated 9 November and 1 December 2020 (O.A. No. 249/2020), added a second layer. Where average ambient air quality in a city or town is "moderate" or below, only green crackers may be sold or used, and only within a two-hour festival window. Where air quality is "poor" or worse, the NGT's order is a total ban on the sale and use of all firecrackers, green included. This is why two neighbouring towns can face different rules in the same festival season: the trigger is that season's measured air quality, not a fixed map.

Layer Three: What Each State Adds on Top

Beyond the national floor, individual states, union territories and city pollution control bodies issue their own yearly notifications. Delhi is the best-documented example: the Delhi Pollution Control Committee has repeatedly imposed additional total bans on the manufacture, storage, sale and bursting of all firecrackers, including green ones, going further than the national baseline. Other states set their own hours within the two-hour ceiling; Tamil Nadu, for instance, notified a 6 am to 7 am and 7 pm to 8 pm window for Deepavali 2025, rather than the national 8-10 pm default, according to reporting by The Hindu. These are illustrative examples of how the third layer behaves, not a current list. Because state and city notifications are re-issued each year and can change, the rule that applies to you must come from that year's notification, not from a previous festival season's news coverage.

Why There Is No Permanent Per-State Table

A table that lists "Delhi: banned, Tamil Nadu: allowed 6-8pm, Karnataka: allowed 8-10pm" looks useful, but it goes stale the moment the next festival season's notifications are issued, and different cities inside the same state can face different rules depending on local air quality. Any page claiming a fixed, permanent per-state list is out of date by definition. The reliable approach is the one above: know the two national layers, then check your state or city pollution control board and local police for the current year's notification before you buy or burst anything.

What to Check Before You Buy

Three checks cover almost every situation. First, is the product green-certified, carrying the CSIR-NEERI logo and a scannable QR code? Second, what does your state or city's current-year notification say about the bursting window, since it may differ from the national 8-10 pm default? Third, has your city's air quality pushed it into the NGT's "poor or worse" bracket for this festival season, which would mean a total ban regardless of what was allowed last year? Get those three answers from your state pollution control board's website or your local police advisory, not from a general search result.
