Diwali

Etymology and Overview

Diwali, from the Sanskrit Deepavali ("row of lamps"), is among the most widely celebrated festivals of South Asian religious life, observed by Hindus, Jains, and Sikhs, each attaching a distinct historical or spiritual narrative to the same calendrical occasion: the new moon (amavasya) of the lunar month of Kartik, typically falling in October or November. Across traditions the common thread is the lighting of oil lamps (diyas) to mark the triumph of light over darkness, though the specific event commemorated differs by community. The festival's antiquity is attested outside purely devotional sources: the 11th-century scholar Al-Biruni, in his account of India, describes a festival of lamps already well established in the region, and references to a Kartik lamp festival appear in Indian literary and inscriptional sources from at least the Gupta period onward.

Hindu Observance

In most of northern, western, and central India, Diwali is associated with the Ramayana: the return of Rama, his wife Sita, and his brother Lakshmana to the city of Ayodhya after fourteen years of exile and Rama's defeat of the demon king Ravana of Lanka, an event the citizens of Ayodhya are said to have marked by lighting rows of earthen lamps. In parts of southern India, particularly Tamil Nadu and Karnataka, greater emphasis falls on Naraka Chaturdashi, commemorating Krishna's defeat of the demon Narakasura. Across regions, the central rite of the festival is Lakshmi Puja, worship of the goddess of wealth and prosperity, who is believed to visit and bless homes that are clean, lit, and welcoming on this night; Ganesha is typically worshipped alongside her as remover of obstacles.

Jain Observance

For Jains, Diwali marks the anniversary of the nirvana, or final liberation from the cycle of rebirth, of Mahavira, the last of the twenty-four Tirthankaras, traditionally said to have attained this state at Pawapuri in present-day Bihar. Jain tradition dates this event, by its own reckoning, to 527 BCE, though as with much early Indian chronology the precise historical date is not independently verifiable. Jain communities mark the day with fasting, meditation, and the lighting of lamps symbolizing the light of knowledge Mahavira is said to have left behind; the Jain New Year is observed separately, on the day following.

Sikh Observance

Sikhs observe the same date as Bandi Chhor Divas ("Day of Release of Prisoners"), commemorating the release of the sixth Guru, Guru Hargobind, from imprisonment at Gwalior Fort by the Mughal emperor Jahangir in 1619, along with a number of Hindu princes also detained there; tradition holds that the Guru secured their release by having each prince hold a tassel of his cloak as he departed. His arrival at Amritsar was greeted with the lighting of lamps at the Golden Temple (Harmandir Sahib), and the illumination of the Golden Temple on this date remains the centerpiece of Sikh observance today.

The Five Days

In its most developed Hindu form, Diwali unfolds over five days. Dhanteras (day one) is dedicated to wealth and, via the god Dhanvantari, to health, and is marked by the purchase of gold, silver, or new utensils. Naraka Chaturdashi, or Choti Diwali (day two), commemorates Krishna's victory over Narakasura and is marked by an early ritual bath and small-scale fireworks. Diwali proper, or Lakshmi Puja (day three), is the principal night of the festival, centered on worship of Lakshmi and Ganesha, the lighting of diyas, rangoli decoration, and fireworks. Govardhan Puja (day four) commemorates Krishna's lifting of Mount Govardhan to shelter the residents of Vrindavan from storms sent by Indra, marked in many communities by the Annakut offering of large quantities of food; in western India the day is also observed as Padwa, honoring the bond between husbands and wives. Bhai Dooj (day five) closes the festival with a ritual honoring the bond between brothers and sisters, comparable in spirit to Raksha Bandhan.

Regional and Global Observance

In Nepal, the equivalent five-day festival is called Tihar or Swanti, with days dedicated in turn to crows, dogs, cows, Govardhan Puja and Mha Puja (self-worship in Newar tradition), and Bhai Tika, the Nepali counterpart to Bhai Dooj. Large Indian-origin diaspora communities observe Diwali as a major public and often official holiday outside South Asia, notably in Mauritius, Trinidad and Tobago, Fiji, Guyana, Suriname, Malaysia, Singapore, and South Africa — communities substantially descended from 19th- and early 20th-century indentured laborers who carried the festival's observance with them. In the United Kingdom, the city of Leicester hosts one of the largest Diwali celebrations outside India, and the festival is marked by public lighting displays and civic recognition in cities across North America and by illumination of prominent landmarks internationally.

Customs

Preparations typically begin weeks in advance with home cleaning, redecoration, and the purchase of new clothes and gifts. Rangoli, patterns made at thresholds from colored powder, rice, or flower petals, are believed to invite prosperity and welcome guests, human and divine. Regional sweets and savory dishes vary widely — ladoos, barfis, and jalebis in the north; murukku and adhirasam in the south; mohanthal and chakli in Gujarat; sandesh and rasgulla in Bengal. Fireworks, historically central to the festival's symbolism of light overcoming darkness, have in recent years drawn increasing scrutiny for their contribution to air pollution in Indian cities, prompting government restrictions in some states and a shift toward lower-emission "green" firecrackers.
