The customs behind the five days — what each one is for, how they change from region to region, and how families keep them going far from where they started.
The short version. Diwali is five days long. Homes are cleaned and lit with rows of oil lamps, doorsteps are decorated with rangoli, sweets are made and shared, the evening puja on the main day honours Lakshmi, and the last day brings brothers and sisters together. Almost every detail below varies by region, community and family — there is no single correct way to keep it.
Looking for dates? Diwali 2026 falls on Sunday, November 8; Diwali 2027 falls on Thursday, October 28 in the United States, and Diwali 2028 on Tuesday, October 17.
The season opens with cleaning — floors, cupboards, the corners nobody looks at — on the idea that Lakshmi enters a house that is ready for her. The first lamps go out by the door. Many families buy something in metal that day: gold, silver, or simply a new steel pot for the kitchen. Dhanvantari, associated with healing, is honoured, and in some homes the day doubles as a small blessing of the household's health.
Chhoti Diwali in the north, Kali Chaudas in Gujarat and Bengal. In South India this is the principal Deepavali day: the household rises before dawn for abhyanga snana, a ceremonial oil bath, then puts on new clothes and eats sweets before sunrise. Where it is Kali Chaudas, the evening turns toward Kali and the clearing away of what is unwanted.
The main night. Diyas are set along doorways, windowsills, balconies and stairs, and the puja to Lakshmi and Ganesha is performed after sunset. Account books are blessed in business families — Chopda Pujan in Gujarat. In Bengal, Odisha and Assam the same night is Kali Puja, a different observance with its own rites.
Also Annakut, the “mountain of food”: dozens of dishes are cooked and arranged as an offering, recalling Krishna lifting Mount Govardhan to shelter his village. In Maharashtra the day is Bali Pratipada. In Gujarat it is Bestu Varas, new year's day, when people call on relatives and settle the year's accounts.
Sisters apply a tilak to their brothers' foreheads and pray for their long life; brothers travel to visit, bring a gift, and stay for the meal. Called Bhai Beej, Bhau Beej or Yama Dwitiya depending on where you are. For many families spread across cities or countries, this is the day the phone rings most.
In Maharashtra and parts of Gujarat the season opens a day earlier with Vasu Baras, honouring cows and calves. It is why some family calendars count six days rather than five — a good example of how much the shape of Diwali depends on which household you grew up in.
The lamp is the one constant. Traditional diyas are small clay bowls with a cotton wick floating in oil or ghee, set out in rows — the word Deepavali literally means a row of lamps. Strings of electric lights and candles sit alongside them in most homes now, and in American apartments with smoke detectors and no-flame rules, LED diyas do the same job.
The doorstep gets its own decoration. Rangoli is a pattern drawn on the floor in coloured powder, rice flour, or flower petals; in Tamil Nadu the same practice is kolam, drawn in rice flour early each morning. Above the door goes a toran — a string of marigolds and mango leaves. All of it points the same way: the entrance is prepared, and a guest, or a goddess, is expected.
Diwali cooking is done in quantity, because most of it is meant to leave the house. Mithai — ladoo, barfi, kaju katli, jalebi, soan papdi — is boxed and carried to neighbours, colleagues and temple. Alongside it come savoury snacks: chakli and chivda in Maharashtra, murukku in the south, mathri and namkeen in the north, all of it made in batches large enough to feed whoever arrives.
Regional signatures run deep. A Gujarati household's Diwali table is not a Tamil household's, and a Bengali family observing Kali Puja is cooking something else entirely. If you have ever wondered why two friends describe Diwali food completely differently, that is why.
New clothes are traditional, often bought in the weeks before and worn first on the main day. Gifting between families is usually food — sweets, dry fruits, tins of nuts — rather than objects, and it moves in both directions between households. Employers in India give Diwali bonuses; in the US the equivalent is often a box of sweets brought into the office.
Firecrackers have been part of Diwali night for generations, and they are also the part that has changed most. Air-quality concerns in Indian cities have driven restrictions and a move toward green crackers or none at all. In the United States, most municipalities restrict consumer fireworks in November regardless, so families lean on lamps, community displays and light installations instead. Plenty of households now keep the noise for the temple event and keep the house quiet.
Several traditions keep this date for reasons of their own, and it is worth naming them accurately rather than folding them together.
Around seven in ten Indian Americans celebrate Diwali, according to Pew Research Center — including 95% of Hindus and 45% of those who are not Hindu. It is also observed in Nepali, Sri Lankan, Guyanese, Trinidadian, Fijian and Indo-Caribbean households, each bringing its own version.
What changes in translation is mostly timing and scale. The main day is rarely a day off, so the puja happens in the evening after work and school, and the larger gathering moves to the nearest weekend. Temples and cultural associations run melas that pull several hundred families together. School recognition is growing — New York City public schools have closed for Diwali since 2024, Pennsylvania recognised the holiday in 2024, and Connecticut's took effect in 2025 — but there is no federal holiday, so most of the celebration is still built around ordinary working weeks.
The quieter change is generational. The grandparents in the room learned these customs by doing them in a place with a different climate, a different market and different neighbours. The grandchildren are learning a version already adapted twice over. Almost nobody writes down what happened in between.
Diwali puts three generations in one room and gives them a reason to talk about the past. These are worth asking while the sweets are out and nobody is in a hurry. Ask one, then stay quiet longer than feels comfortable — the second answer is usually the real one.
Most families mean to record these conversations and never do. StoriedLife is an AI biographer that interviews a parent or grandparent the way a patient interviewer would — spoken conversation, no writing, no typing — and turns their answers into a written life story in their own words, including the parts about the place they came from and the traditions they carried over.

Cleaning and decorating the home, lighting rows of oil lamps called diyas, drawing rangoli patterns at the doorway, hanging a marigold toran, making and sharing sweets, wearing new clothes, and performing the evening Lakshmi Puja on the main day. The five-day structure runs from Dhanteras through Naraka Chaturdashi, Lakshmi Puja and Govardhan Puja to Bhai Dooj.
The lamps stand for light over darkness and knowledge over ignorance. In North Indian tradition they also recall the lamps lit in Ayodhya to guide Rama, Sita and Lakshmana home from exile. The word Deepavali means a row of lamps, which is where the name comes from.
Rangoli is a pattern made on the floor at the entrance of a home using coloured powder, rice flour, sand or flower petals, meant to welcome guests and good fortune. In Tamil Nadu the equivalent daily practice is kolam, drawn in rice flour. Many families now use stencils or reusable mats, which is a practical adaptation rather than a departure.
Considerably. In South India the main observance is Naraka Chaturdashi, beginning before dawn with a ceremonial oil bath. In Bengal, Odisha and Assam the main night is Kali Puja rather than Lakshmi Puja. In Gujarat the day after Diwali is Bestu Varas, the new year. In Maharashtra the season opens early with Govatsa Dwadashi. Food, and the order of the days, changes with the region.
Sweets, or mithai, are central: ladoo, barfi, kaju katli, jalebi and soan papdi among many others, usually boxed and shared with neighbours. Savoury snacks vary by region — chakli and chivda in Maharashtra, murukku in the south, mathri and namkeen in the north. Much of the cooking is done specifically to be given away.
Yes, though usually food rather than objects. Boxes of sweets, dry fruits and nuts move between households, neighbours and colleagues. In India employers commonly pay a Diwali bonus. Elaborate personal gifts are less central to Diwali than they are to some other holidays.
Usually in the evening, since Diwali is not a federal holiday, with the larger family gathering moved to the closest weekend. Temples and cultural associations hold community melas. Fireworks are mostly replaced by lamps, LED diyas and organised light displays, because consumer fireworks are restricted in most municipalities in the autumn.
Being invited to a Diwali celebration is normal and being welcomed is the point of the festival. Bring sweets or flowers, take your shoes off if others do, ask before photographing a puja, and follow the household's lead. “Happy Diwali” is a widely welcome greeting; for Sikh families, “Happy Bandi Chhor Divas” is often preferred.
