What Is Diwali? A Simple Guide for Friends and Colleagues
Quick answer: Diwali is a festival of lights celebrated by many Hindus, Jains, Sikhs and some Buddhists, with different meanings and customs across communities. Celebrations often include lamps, family visits, food and gifts. In 2026, Diwali, Lakshmi Puja, falls on Sunday 8 November. “Happy Diwali” is a warm greeting for someone celebrating.
If a friend invites you to Diwali dinner or a colleague mentions taking leave, you do not need detailed knowledge to respond thoughtfully. A greeting, interest in their plans and respect for their time are good starting points. Let the person tell you what the occasion means in their home.
A festival with many family traditions
The name Diwali is commonly associated with rows of lights. You may see small oil lamps called diyas, decorative lights, colourful rangoli patterns and flowers at entrances. Homes and community spaces can become places for gathering, sharing food and spending time with relatives.
Many Hindu celebrations describe the festival through themes of light, goodness and new beginnings. Other communities have their own histories and observances associated with this time. Customs vary by region and family, so one colleague's dinner or prayer tradition will not explain everyone's Diwali.
Some people celebrate with worship, while others focus on family, food or a community gathering. A person may keep the day quietly, attend an event on a nearby weekend or travel to see relatives. Avoid deciding how religious or elaborate their celebration should be.
The five days in 2026
Diwali is often described as a five-day festival. The following sequence is a useful introduction for friends in the US and UK. Names, observances and calendar choices can differ; check your host's plans before assuming a particular day is their main gathering.
| Day | Date | Common descriptions |
|---|---|---|
| Dhanteras | Friday 6 November | Festive preparations and traditional purchases |
| Choti Diwali | Saturday 7 November | Preparations, lights and family customs |
| Diwali, Lakshmi Puja | Sunday 8 November | Lamps, worship in many homes and gatherings |
| Govardhan Puja | Monday 9 November | Community and family observances in some traditions |
| Bhai Dooj | Tuesday 10 November in most calendars | A celebration of the sibling bond; check your family calendar |
A London or US community celebration may be held on a different date to fit the organiser's programme. Use the invitation for the event time. The festival calendar helps explain the season, while the host's details tell you when and where to arrive.
What you might see at a gathering
Diyas and decorative lights are familiar sights. Rangoli patterns may be made with coloured powders or flowers near an entrance. Give them space as you enter. If someone is lighting lamps or preparing a prayer area, ask where you can sit or help instead of moving things to make room.
There may be sweets, snacks and a shared meal, depending on the household. Tell your host about dietary requirements when accepting the invitation. Ask before photographing people, home shrines or private rituals, and wait for an invitation before joining any religious part of the evening.
How to wish someone a happy Diwali
“Happy Diwali” is enough. You could add, “Wishing you and your family a lovely celebration.” In a work message, “Happy Diwali, I hope you enjoy your time with family” is warm and easy to understand. You do not need to copy a greeting in an unfamiliar language.
If you are unsure whether someone celebrates, ask about their plans without making assumptions from their name or nationality. Once they mention celebrating, follow their lead. Save detailed questions for a moment when they have time and seem comfortable discussing them.
Office etiquette and a simple gift
Respect leave and avoid scheduling optional meetings over a colleague's celebration where possible. Acknowledge the occasion without asking one person to represent every Indian community. Make team activities optional and ask about venue arrangements before bringing lamps, food or decorations into a workplace.
A small box of sweets or another modest food gift can work for a host after checking preferences and dietary needs. A personal greeting can also be enough. For a colleague, follow your workplace's gift policy and keep the gesture comfortable for the relationship. An invitation does not require an expensive present.
