Diwali - the 5-day Hindu festival of lights, lunar date, and how it is observed across India

Diwali (also Deepavali) is the 5-day Hindu festival of lights, observed on the new moon of Kartik. It is one of the largest holidays in India and a major celebration across Hindu, Sikh, and Jain communities worldwide.

The one-line summary

5-day Hindu festival of lights on the new moon of Kartik. Celebrates the return of Lord Rama, the goddess Lakshmi, and (in Sikh and Jain traditions) related religious events. The largest commercial event of the Indian calendar.

When it falls

Diwali falls on the new moon (Amavasya) of the Hindu month of Kartik (October-November Gregorian). The 5-day festival begins two days before the new moon (Dhanteras) and ends two days after (Bhai Dooj). In 2026, Diwali falls on November 8 (Sunday), with the main Lakshmi Puja on the evening of November 8. In 2027, Diwali falls on October 28 (Thursday). The exact Gregorian dates shift each year because the Hindu lunisolar calendar does not align with the Gregorian.

Origin

Diwali has multiple religious origins, with the festival fusing multiple regional traditions over centuries. The dominant Hindu narrative is the return of Lord Rama to Ayodhya after defeating Ravana, the demon king of Lanka, as told in the Ramayana. The people of Ayodhya lit lamps to welcome Rama home.

In North India, Diwali is also strongly associated with the goddess Lakshmi, the deity of wealth and prosperity. In South India, the festival commemorates Krishnas victory over Narakasura. The Sikh tradition commemorates the release of Guru Hargobind from Gwalior prison in 1619, and Jain tradition commemorates Mahaviras attainment of moksha.

How it is observed

The 5 days are Dhanteras (day 1, cleaning and Lakshmi puja), Choti Diwali (day 2), Diwali / Lakshmi Puja (day 3, main day, the new moon), Govardhan Puja (day 4), and Bhai Dooj (day 5, sibling festival). Customs include lighting clay lamps (diyas), fireworks, exchanging sweets and gifts, cleaning and decorating homes, performing puja, and wearing new clothes.

Legal status

Diwali is a gazetted public holiday in India. Banks, government offices, and most businesses close. Stock markets (BSE, NSE) close for the main day. Schools close for 2-5 days depending on the state. Diwali is a public holiday in Nepal, Sri Lanka, Malaysia, Singapore, Fiji, and Trinidad and Tobago.

Where it is contested

Diwali is broadly accepted. Environmental critiques of fireworks and concerns over child labor in firework manufacturing have produced state-level regulations on cracker hours and on licensed manufacturers. These have not produced any alteration of the holiday itself.

In other countries

Diwali is observed across the Hindu, Sikh, and Jain diasporas worldwide, especially in the UK, Canada, the US, Australia, and the Gulf states. Several cities host public Diwali events: Leicester (UK), Trafalgar Square (London), Times Square (New York), and Sydney host annual Diwali festivals.

Detailed origin narratives

The Ramayana-based narrative - Rama, Sita, and Lakshman returning to Ayodhya after 14 years of exile and the defeat of Ravana - is the most widely told Diwali origin across North India and the diaspora. The return is celebrated by lighting rows of oil lamps (diyas) along rooftops, in courtyards, and across streets. The festival timing aligns with the lunar month of Kartik and the return-to-home symbolism is reflected in the Indian tradition of returning to one's hometown (similar to Spring Festival in China).

The Lakshmi association is dominant in merchant communities and in the western and southern states where Diwali marks the beginning of the new financial year (the Gujarati new year, Bestu Varas, falls on the day after Diwali). Lakshmi puja on the main Diwali night is performed by businesses to welcome wealth into the new financial year. The worship involves cleaning the premises, lighting lamps, drawing rangoli, and offering sweets to the goddess.

The Narakasura narrative is prominent in South India (particularly Tamil Nadu, Karnataka, and Andhra Pradesh), where Diwali is called Deepavali and marks Krishna's destruction of the demon Narakasura. The day before Diwali (Naraka Chaturdashi) is a major bathing day, and the festival is associated with oil baths, new clothes, and early-morning celebrations. South Indian Diwali traditions differ from North Indian ones in several respects: the emphasis on Krishna rather than Rama, the bathing ritual rather than Lakshmi puja, and the role of household goddesses.

The Sikh Bandi Chhor Divas (literally "prisoner release day") celebrates the release of Guru Hargobind from Gwalior Fort in 1619. The Guru had been imprisoned by the Mughal emperor Jahangir; on release he returned to the Harmandir Sahib (Golden Temple) in Amritsar, where the Sikhs lit lamps to welcome him. Bandi Chhor Divas coincides with Diwali by date and is observed in gurdwaras with the same lamp- lighting tradition. The Jain Mahavir Jayanti / Diwali celebration marks the day Mahavira attained moksha (liberation from the cycle of rebirth) in 527 BCE. Jain temples especially in Gujarat and Rajasthan observe this date with readings of Mahavira's teachings.

Economic and cultural impact

Diwali is the largest commercial event of the Indian calendar. The Confederation of Indian Industry estimates annual Diwali-related spending at roughly 4-5 lakh crore rupees (about $50-60 billion USD) across consumer goods, gold and silver purchases, household items, gifts, and sweets. Gold and silver purchases are particularly heavy in the week before Diwali, with buyers treating the purchase as both a financial investment and a Lakshmi-related auspicious gesture. The Indian stock markets (BSE, NSE) close for the main Diwali day, and trading volumes in the preceding week are typically elevated by retail investors making auspicious purchases.

Internationally, Diwali has become a significant consumer and cultural event. In the UK, Diwali is observed as a public event in cities with large Indian-heritage populations (Leicester, London, Birmingham, Manchester). In the US, Diwali has been recognized by the State of Pennsylvania (2017), the city of New York (annual Diwali at Times Square), and various school districts that close for the day. The White House has hosted Diwali celebrations under Presidents Obama, Trump, and Biden. Diwali has been designated an official school holiday in New York City since 2023.

Religious observance and commercial celebration co-exist but also tension. Critics note that fireworks emissions contribute to Delhi NCR's notoriously poor Diwali air quality (PM2.5 levels routinely exceed 500 micrograms per cubic meter in the days after Diwali), and the child labor in Sivakasi's firecracker industry has been a documented concern. Several Indian states have imposed time-window restrictions on Diwali fireworks; the Supreme Court of India ruled in 2018 that fireworks are permitted only during designated hours (8-10 pm on Diwali night and the day before).

The five days in detail

The five days of Diwali carry distinct significance. Day 1, Dhanteras (literally "wealth day"), marks the start of the festival and is dedicated to the goddess Lakshmi and to Dhanvantari, the physician of the gods. Houses are cleaned, gold and silver are purchased, and small clay lamps (diyas) are lit. Day 2, Choti Diwali or Naraka Chaturdashi, commemorates Krishna's destruction of the demon Narakasura and is marked by an early-morning oil bath (ubtan) symbolizing the cleansing of past sins.

Day 3 is the main Diwali day: Lakshmi Puja, observed on the new moon of Kartik. Houses are decorated with rangoli (colored powder patterns), lamps are lit at dusk, and Lakshmi puja is performed to welcome the goddess into the home. The timing of Lakshmi puja is determined by the Lagna (auspicious alignment) and varies by region. Fireworks follow the puja. Day 4, Govardhan Puja or Padwa, marks the anniversary of Krishna's lifting of Mount Govardhan to protect the villagers of Vrindavan from Indra's storm. In some regions, this day is the Gujarati New Year (Bestu Varas). Day 5, Bhai Dooj, is the sibling festival where brothers visit sisters and the sister applies a tilak on the brother's forehead.

Regional traditions

Diwali traditions differ notably across regions of India. In Gujarat and Maharashtra, the festival is closely tied to the New Year and Lakshmi puja, with business account books (chopda) being opened on Day 1 of the new year. In Tamil Nadu, Deepavali is more focused on Krishna and Narakasura, and the day-2 oil bath is a major feature. In Bengal and Odisha, Kali puja is performed alongside or instead of Lakshmi puja, and the festival overlaps with the Shyama Puja tradition. In Punjab, Bandi Chhor Divas is the dominant theme and gurdwaras hold large gatherings. In South India, the celebration lasts 3 days rather than 5.

Within Nepal, Diwali (called Tihar) follows a five-day structure but with distinct symbolism: the first three days honor crows, dogs, and cows respectively, the fourth day is the main Lakshmi day, and the fifth day is Bhai Tika (the sibling festival). In Sri Lanka, Diwali is observed by the Tamil minority. In Malaysia and Singapore, Diwali is a public holiday observed with open houses and visits between Indian, Malay, and Chinese communities. In Fiji, Mauritius, Trinidad and Tobago, Guyana, and Suriname, the Indian diaspora observes Diwali with public events.
