What is Diwali, the Festival of Lights, and how is it celebrated?

Diwali is a major festival celebrated especially by Hindus in India and its diaspora. It is also observed by Sikhs, Jains, and some Buddhists. The festival centers on prayers, family gatherings, feasting, gifts, and light. Its deeper message is the victory of good over evil, light over darkness, and knowledge over ignorance.

The name Diwali comes from “Deepavali,” meaning “a row of lights.” Celebrants place rows of traditional clay oil lamps outside their homes. They also light fireworks, wear new clothes, exchange sweets, and create colorful rangoli designs. These visible traditions make the festival’s meaning part of everyday surroundings.

Diwali follows the Hindu lunar calendar and usually arrives in late October or early November. In 2026, it falls on Nov. 8. More than one billion people celebrate it across faiths in India and its diaspora, making its lights both a religious tradition and a major community celebration.

Diwali celebrations bring religious practice and family life together. Homes and communities commonly mark the festival with prayers, lights, fireworks, feasting, new clothes, and visits with relatives and friends. Rangoli designs add bright geometric and floral patterns to floors. These traditions create a shared celebration that is both personal and public.

Regional customs give the festival different textures. In southern India, many people take an early morning warm-oil bath. This symbolizes bathing in the holy River Ganges for physical and spiritual purification. In northern India, worship often centers on Lakshmi, the goddess associated with wealth and prosperity. Families may also exchange sweets and gifts.

Firecrackers are another popular tradition, and gambling is linked to hopes of prosperity during the coming year. Many people buy gold on Dhanteras, the festival’s first day, believing it brings good luck. Communities also organize public events, including performances, cultural bazaars, and lighting countdowns.

The article reports that more than one billion people across faiths celebrate Diwali in India and its diaspora. It is especially important for Hindus, but Sikhs, Jains, and some Buddhists also observe it. This scale makes Diwali one of the world’s largest religious and cultural festivals, combining household rituals with public gatherings.

Celebrations extend beyond India through diaspora communities. In 2026, Disney World in Florida held several days of festivities featuring more than 500 dancers. New York’s Diwali at Times Square included international performers, cultural bazaars, and a lighting countdown at the Ball Drop Tower.

Other North American events included Diwali Eve on the Waterfront in Jersey City, a family cruise on New York’s Hudson River, Diwali on the Bay in San Francisco, and a Bollywood boat party in Vancouver. These events show how communities preserve traditions while adapting them to local public spaces.

Diwali’s stories differ across India, but they share a central theme: good triumphing over evil. The festival therefore connects regional religious traditions to a broader message about justice, courage, and the defeat of wrongdoing. The article describes two especially important origin stories from southern and northern India.

In southern India, Diwali celebrates Lord Krishna’s victory over the demon Naraka. Naraka was said to have imprisoned women and tormented his subjects. In northern India, the festival honors the triumphant return of Lord Rama, his wife Sita, and his brother Lakshmana after 14 years of exile in the forest.

These stories help explain why light, celebration, and family gatherings are central to Diwali. Lamps and fireworks express the victory of light over darkness, while regional prayers and customs keep each story meaningful. Although the narratives vary, they give the festival a shared moral foundation across India.

Diwali is not interpreted in exactly the same way by every faith that observes it. Hindus connect it with regional stories of good defeating evil and commonly include prayers, lamps, fireworks, feasting, and family gatherings. Jains, Sikhs, and some Buddhists attach their own religious histories and meanings to the date.

Jains observe Diwali as the day Lord Mahavira, the last of their great teachers, attained nirvana. Sikhs celebrate Bandi Chhor Divas, which overlaps with Diwali, to commemorate Guru Hargobind’s release from imprisonment under the Mughal emperor Jahangir. These observances share the calendar period but have distinct religious purposes.

Some Buddhists mark the day as the anniversary of Emperor Ashoka’s conversion to Buddhism in the third century B.C. Across these traditions, practices and meanings vary. The shared festival period brings different communities into public celebrations while preserving their separate histories and beliefs.

Making Diwali an official state holiday means California formally recognizes the festival at the state level. The article identifies California as the third U.S. state to take this step. It does not specify whether the designation closes government offices, changes school schedules, or creates other legal requirements, so those effects cannot be assumed from the source.

The recognition reflects Diwali’s growing public presence in the United States. Communities already hold large celebrations, such as Diwali at Times Square, events in New Jersey and San Francisco, and a Bollywood boat party in Vancouver. Disney World in Florida also held several days of festivities featuring more than 500 dancers.

An official holiday can make a community’s religious and cultural tradition more visible in public life. It may support broader awareness and participation, while local celebrations continue through prayers, performances, lights, food, and family gatherings. The article provides no further details about California’s implementation.

A lunar calendar measures months by the phases of the moon, so its dates do not line up with the fixed dates of a solar calendar. As a result, a festival tied to a lunar calendar can move from year to year when viewed on the standard calendar used for most civil dates. The source identifies Diwali as following the Hindu lunar calendar.

That calendar explains why Diwali typically falls in late October or early November instead of on one permanent date. The festival’s timing is therefore predictable within a general season but not fixed to a single day. In 2026, the article states that Diwali falls on Nov. 8.

The changing date affects planning for prayers, family gatherings, public events, and travel. It also means communities check the religious calendar each year before announcing celebrations. The article does not explain the calendar’s detailed rules; the explanation of lunar calendars here uses established general knowledge.
