Diwali / Lakshmi Puja

Significance and story

Diwali, known in many homes as Deepavali, is observed on Kartik Amavasya — the new moon that closes the lunar month of Kartik. The night is kept in honour of Lakshmi, the goddess of prosperity and abundance, and Ganesha, who is invoked before her as the remover of obstacles. Together they are worshipped so that the household may be blessed with steadiness and well-being in the year ahead.

The festival belongs to the wider body of Hindu observance rather than to a single region or community. It is pan-India in reach, and it travels with Hindu families wherever they have settled. The essential act is simple and old: lamps are lit, a clean and welcoming space is prepared, and the goddess is invited into the home. In many retellings, the day also marks the return of Rama to Ayodhya, and rows of lamps are said to have welcomed him home. The two strands — the prosperity of Lakshmi and the homecoming of Rama — sit comfortably together, which is part of why the festival is so widely shared.

Because the observance falls on Amavasya, the darkest night of the lunar month, the lamps carry their own meaning. Light is not merely decorative; it is the offering. A home lit against the new moon is a home that has made itself ready to receive.

How the date is fixed

Diwali is not fixed to a Gregorian date. It is fixed to Kartik Amavasya, and the Gregorian date is computed each year from the panchang. That is why the festival moves from year to year, and why the exact date for a given year is best read from the panchang rather than carried over from memory. The dates shown on this page are computed for the year and listed alongside this guide.

The puja itself is performed during Pradosh kaal, the window around sunset. This is the period traditionally prescribed for Lakshmi puja on this day. Readers who want the precise muhurat for their city should consult a local panchang or a qualified jyotishi, since the window shifts with place.

It is also worth knowing that Hindu festival dates follow the tithi, nakshatra or solar ingress at a place, so they can shift by a day between cities, and between the amanta and purnimanta reckonings of the lunar month. Different communities and regions may therefore observe the festival on adjacent days. This is a normal feature of the calendar, not a contradiction. The dates given here are computed for New Delhi sunrise with Lahiri ayanamsha; readers elsewhere may see a difference of a day.

Puja vidhi

The form of the puja varies by family and region, but the broad shape is widely shared. A clean space is prepared, often near the entrance or in the place of daily worship. Lamps — usually earthen diyas — are arranged and lit. Lakshmi and Ganesha are invoked, offerings are made, and the household sits together for the aarti.

Common elements include:

• Cleaning and decorating the home before the evening, so that the space is ready to receive.
• Lighting diyas at dusk and placing them at doorways, windows and along the walls.
• Worshipping Lakshmi and Ganesha together, with Ganesha remembered first.
• Offering sweets, fruit and flowers according to family custom.
• An aarti with the whole household present, followed by the sharing of prasad.

Households differ on the details — which mantras are recited, whether a priest is called, whether the puja is long or short. What is consistent is the intent: to welcome prosperity and remove obstacles, and to do so in a home that has been made clean and bright for the occasion.

Regional variations

Diwali is observed across India and in the diaspora, and the ways of keeping it differ. In many parts of North India, the focus on Lakshmi puja in the evening is central, with the business year and household accounts sometimes opened afresh. In other regions, the same Amavasya carries different local stories and customs, and the day may be associated with other events in the epic and Puranic traditions.

There are also differences in reckoning. Communities that follow the amanta calendar and those that follow the purnimanta calendar may name or place the month differently, which can affect how the festival is dated locally. Smarta and Vaishnava households may give slightly different emphasis in the order of worship. None of these variations is treated as a correction of another; they are simply different inherited traditions, and each is observed in its own place. Where a family is unsure, the practice of the household's own elders and local panchang is the usual guide.

What to avoid

A few cautions are worth stating plainly. First, do not treat any festival date as predictive for an individual. Diwali is an occasion of observance, not a promise of any particular outcome in health, money, marriage or legal matters, and nothing here should be read that way. Second, do not rely on a single date carried over from another year or another city; check the panchang for your place, and remember the amanta and purnimanta difference noted above. Third, the puja muhurat is a window, not a rule that invalidates the whole evening — families who cannot manage the exact Pradosh kaal still keep the festival with sincerity.

For personal questions about your own chart, the appropriate step is to consult a qualified jyotishi. This page is a festival guide: it explains why the day is kept, how the date is fixed from the panchang, and how it is observed across regions.
