When Diwali falls each year, the Lakshmi Puja muhurat, the five days of Deepavali, and how families celebrate across India.
The Significance of Diwali
Diwali (Deepavali, "row of lamps") is the most widely celebrated Hindu festival and falls on the Amavasya (new-moon) of the lunar month of Kartik – the darkest night of the year – which is precisely why it is marked with rows of oil lamps (diyas) and lights. Its core meaning is the victory of light over darkness, knowledge over ignorance, and good over evil.
Several spiritual strands converge on this night. (1) Return of Rama: in North India, Diwali commemorates Lord Rama's return to Ayodhya after 14 years of exile and his victory over the demon king Ravana; the people of Ayodhya lit lamps to welcome him, the origin of the diya tradition. (2) Worship of Goddess Lakshmi: on Amavasya night, Goddess Lakshmi (consort of Vishnu, goddess of wealth, fortune and prosperity) is believed to walk the earth and bless clean, well-lit, welcoming homes – hence the central rite of Lakshmi Puja, usually performed alongside Lord Ganesha (remover of obstacles) and often Goddess Saraswati and Kubera. (3) The churning of the ocean (Samudra Manthan): Lakshmi is said to have emerged from the cosmic ocean on this day. (4) Krishna's victory over Narakasura the previous day (Naraka Chaturdashi), celebrated especially in the South.
The Lakshmi Puja muhurat is anchored to Pradosh Kaal – the roughly 2 hour 24 minute window just after sunset – performed while Amavasya tithi prevails. Within that, astrologers prize the Vrishabha (Taurus) Lagna because it is a 'Sthir' (fixed) lagna: worshipping Lakshmi during a fixed lagna is believed to make the goddess 'stay' in the home, i.e. bring stable, lasting prosperity rather than fleeting gain. This is why the published puja window is a short slice inside the broader Pradosh period.
How Diwali is celebrated across India
Diwali is a five-day festival, and how it is observed varies sharply by region.
NORTH INDIA: The Rama-Ayodhya narrative dominates. Homes are deep-cleaned and decorated with diyas, candles, electric lights, rangoli (colored-powder floor art) and torans. Lakshmi-Ganesh Puja on the main night is the centerpiece, followed by fireworks, sweets (mithai) and gift exchange. Dhanteras opens the festival with buying gold, silver and new utensils.
SOUTH INDIA (Tamil Nadu, Andhra/Telangana, Karnataka, Kerala): The main day is effectively Naraka Chaturdashi (called Deepavali here), celebrating Krishna's slaying of Narakasura. The hallmark is the pre-dawn 'Ganga Snanam' – an oil bath before sunrise – followed by new clothes, firecrackers at dawn and a festive feast. The emphasis is on the early-morning of Choti Diwali rather than the new-moon night.
WEST INDIA (Gujarat, parts of Maharashtra/Rajasthan): Diwali coincides with the end of the Vikram Samvat year. The day after Lakshmi Puja is Bestu Varas / Gujarati New Year (Bali Pratipada), and traders perform Chopda Pujan / Sharda Pujan – worshipping new account books to open the financial year. Lakshmi as wealth-bringer is especially central for the business community.
EAST INDIA (West Bengal, Odisha, Assam): The new-moon night is celebrated as Kali Puja – worship of the fierce goddess Kali – rather than Lakshmi Puja, with grand pandals, especially in Kolkata. (Bengalis worship Lakshmi separately on the earlier Kojagari Purnima.) In Odisha and parts of the east, families also perform Kaunriya Kathi, calling upon ancestors.
THE FIVE DAYS (standard sequence): Day 1 Dhanteras (Dhantrayodashi) – Lakshmi/Kubera/Dhanvantari worship, auspicious buying of metals and utensils, Yama Deepam lamp. Day 2 Naraka Chaturdashi / Choti Diwali / Kali Chaudas – Krishna's victory, oil bath in the South. Day 3 Lakshmi Puja (main Diwali) – Amavasya, evening Lakshmi-Ganesh puja, lamps and fireworks. Day 4 Govardhan Puja / Annakut / Bali Pratipada – Krishna lifting Govardhan hill; mountains of food (annakut) offered; Gujarati New Year. Day 5 Bhai Dooj / Bhaiya Dooj / Yama Dwitiya / Bhau Beej – sisters apply tilak and pray for brothers' long life, mirroring Raksha Bandhan. Note: in some years the fourth/fifth days shift by a day depending on whether Amavasya or Pratipada touches the reference sunrise (as in 2026), so cross-check a panchang for the exact local date.
Sending Diwali wishes
Greetings and well-wishing are a major part of Diwali, and the customs span the traditional and the digital. The most common spoken wishes are "Shubh Deepavali", "Happy Diwali", and in the trading/Gujarati context "Saal Mubarak" / "Nutan Varshabhinandan" for the New Year that follows. Families and businesses exchange Diwali greeting cards and gift hampers (dry fruits, sweets/mithai, diyas, decorative items) in the days leading up to the festival, often timed to arrive around Dhanteras.
In recent years a large share of greetings has moved to digital channels: families and businesses send personalized Diwali wish images, animated greeting cards and short greeting videos over WhatsApp, Instagram, and email – frequently customized with the family or company name, a Lakshmi/diya/rangoli motif, and the year. Personalized video greetings and e-cards (where a name or logo is added to a festive Diwali template) have become especially popular for reaching extended family and customers at scale. Businesses commonly send Diwali wishes to clients as a goodwill gesture alongside the start of the new financial year. Elders bless younger family members, sisters and brothers exchange gifts around Bhai Dooj, and many people share a photo of their lit diyas, rangoli or Lakshmi puja thali as a greeting in itself.
Diwali — Frequently Asked Questions
What date is Diwali 2026 and what time is Lakshmi Puja?
Diwali (Lakshmi Puja) 2026 is on Sunday, 8 November 2026 – a date unanimous across Drik Panchang, Prokerala, dekhopanchang, mPanchang and timeanddate.com. The Lakshmi Puja muhurat is approximately 05:54 PM to 07:50 PM IST (within Pradosh Kaal ~05:31 PM to 08:09 PM) for New Delhi per Drik Panchang; Prokerala gives the broader Pradosh window as ~05:41 PM to 08:17 PM and dekhopanchang ~05:48 PM to 07:14 PM. Always localize the timing to your own city, since sunset – and therefore Pradosh – shifts by location.
What are the 5 days of Diwali and their order?
The five days are: Day 1 Dhanteras (buying gold/utensils, Lakshmi-Kubera puja); Day 2 Naraka Chaturdashi / Choti Diwali (Krishna's victory, pre-dawn oil bath in the South); Day 3 Lakshmi Puja, the main Diwali on Amavasya night; Day 4 Govardhan Puja / Annakut (and Gujarati New Year); Day 5 Bhai Dooj, when sisters bless brothers. In 2026, for example, that runs Fri 6 Nov through Wed 11 Nov.
Why does Lakshmi Puja have to be done at a specific muhurat after sunset?
Lakshmi Puja is prescribed during Pradosh Kaal – the ~2 hour 24 minute window right after sunset – while the Amavasya tithi is in effect. Within Pradosh, astrologers prefer the Vrishabha (Taurus) Lagna because it is a 'fixed' (Sthir) lagna; worshipping Lakshmi during a fixed lagna is believed to make prosperity 'stay' in the home. That is why the published puja slot is a short window inside the larger evening period.
What is the best muhurat for new purchases, vehicles, or starting something on Diwali?
The traditional day for auspicious buying is Dhanteras (Day 1), considered ideal for purchasing gold, silver, utensils, vehicles and property; each year's Dhanteras has its own buying muhurat (Pradosh-based) published on panchang sites. For opening new account books or starting a business year, traders use Lakshmi Puja evening and Govardhan Puja / Bali Pratipada (Gujarati New Year). For any big-ticket purchase, check the specific Dhanteras 'Kharidi' muhurat for your city and year rather than a generic time.
Why do some calendars show different Lakshmi Puja or Govardhan Puja dates?
The main Diwali date is fixed by the Kartik Amavasya and is rarely disputed, but two things vary: (1) muhurat clock-times differ by source because some publish the narrow fixed-Lagna window and others the broader Pradosh Kaal, and all depend on local sunset; (2) the 4th and 5th days (Govardhan Puja, Bhai Dooj) can shift by a day depending on whether Amavasya or Pratipada touches the reference sunrise. In 2026, for instance, Drik Panchang places Govardhan Puja on 10 Nov while Prokerala places it on 9 Nov.
Is Diwali always on a new moon (Amavasya)?
Yes. The main Diwali / Lakshmi Puja always falls on the Amavasya (new-moon) of the lunar month of Kartik – the darkest night of the year. The rows of lamps (diyas) are lit precisely because there is no moonlight, symbolizing light dispelling darkness. The Gregorian date therefore moves each year (typically mid-October to mid-November): 8 Nov 2026, 29 Oct 2027, 17 Oct 2028, 5 Nov 2029, 26 Oct 2030.
How is Diwali celebrated differently in South India and Bengal?
In South India the principal day is Naraka Chaturdashi (called Deepavali), marking Krishna's defeat of Narakasura, with a ritual pre-dawn oil bath ('Ganga Snanam'), new clothes and dawn firecrackers – the emphasis is the early morning, not the new-moon night. In West Bengal and much of the East, the Amavasya night is observed as Kali Puja (worship of Goddess Kali) with large pandals, rather than Lakshmi Puja; Bengalis worship Lakshmi separately on Kojagari Purnima two weeks earlier.
How do people send Diwali wishes and greetings to family and friends?
Traditionally families exchange Diwali greeting cards and gift hampers (sweets, dry fruits, diyas) timed around Dhanteras, and elders bless the young. Today most greetings go digital – personalized Diwali wish images, e-cards and short greeting videos shared over WhatsApp, Instagram and email, often customized with the family or business name and a diya/Lakshmi/rangoli motif. Many people also simply share a photo of their lit diyas, rangoli, or puja thali as a greeting. Common phrases are 'Shubh Deepavali', 'Happy Diwali', and 'Saal Mubarak' for the New Year that follows.
