Most of us grow up calling Diwali "the festival of lights" and leave it at that. But Diwali is not one day, it is five, and each day carries its own story and its own correct timing. This guide explains all five days in plain language, and further down, a calculator works out the exact date and time for each puja, calculated fresh for wherever you are reading this from, not copied from a Delhi or Mumbai table.
Diwali is five days, not one: Dhanteras, Naraka Chaturdashi, Lakshmi Puja, Govardhan Puja, and Bhai Dooj. Each has its own correct Tithi-based timing. Use the free tool below to get all five dates and Muhurat windows worked out for your own city and year, in seconds.
The Importance of Puja in a Hindu Home
Before the five days themselves, it helps to understand why puja matters at all. Puja is not simply a ritual performed out of habit. It is a structured way of turning attention away from daily distraction and toward gratitude, discipline, and connection with the divine. Lighting a diya, offering water or flowers, and reciting a name with sincerity are small acts, but tradition holds that they realign a person's mind and home toward light rather than darkness, order rather than neglect.
Diwali takes this idea and multiplies it across an entire household and an entire community. A home that is cleaned, lit, and quiet with prayer is, in the old texts, a home that Lakshmi is willing to enter. The puja is the invitation.
Diwali Is Five Days, Not One (and Not Three)
Here is something worth correcting early. Many people, including many who celebrate it every year, think of Diwali as a single evening, or loosely as "three days." It is neither. Diwali is a five-day sequence, and each day has a distinct name, story, and purpose:
| Day | Name | In One Line |
| 1 | Dhanteras | Buying gold or new utensils, and worshipping Dhanvantari, the god of health |
| 2 | Naraka Chaturdashi (Choti Diwali) | An early oil bath before sunrise, marking Krishna's victory over the demon Narakasura |
| 3 | Lakshmi Puja (Main Diwali) | The main night, worship of Goddess Lakshmi, diyas lit across the home |
| 4 | Govardhan Puja (Annakut) | A mountain of food offered to Krishna, recalling him lifting Govardhan Hill |
| 5 | Bhai Dooj | Sisters pray for their brothers' wellbeing and apply tilak |
Regional practice varies. In parts of South India, Naraka Chaturdashi itself is treated as the main day. In Gujarati households, the festival often begins a day earlier with Vasubaras, and the day after Diwali doubles as the new financial year, marked with Chopda Pujan. None of this is wrong; India's diversity means the same five-day frame is lived out differently in different homes, and that is worth knowing rather than flattening into one version.
Why Each Day Has Its Own Correct Time
This is the part almost no one explains. Each of these five days is tied to a specific Tithi (a lunar day), and classical texts, chiefly the Dharmasindhu and the Nirnaya Sindhu, lay down exactly which part of the day that Tithi must govern for the ritual to be done correctly:
| Day | Correct Timing Rule |
| Dhanteras & Lakshmi Puja | Performed when the correct Tithi rules Pradosh Kaal, the twilight period after sunset, ideally while a Sthir (fixed) Lagna such as Vrishabha is rising. |
| Naraka Chaturdashi | The Abhyanga Snan (oil bath) must be taken before sunrise, while Chaturdashi Tithi is still active. |
| Govardhan Puja | Performed in Pratahkal, the morning hours after sunrise, while Pratipada Tithi governs. |
| Bhai Dooj | The tilak is applied during Aparahna Kaal, the afternoon period, while Dwitiya Tithi governs. |
Because sunrise and sunset shift with your latitude and longitude, these windows are never truly the same in Chennai as they are in Delhi, and never the same in New Jersey as in either. A generic table is, at best, an approximation. The calculator below works this out freshly for your own location.
Day 1: Dhanteras
Dhanteras, or Dhanatrayodashi, falls on Trayodashi, the thirteenth lunar day. "Dhan" means wealth. The day is dedicated to Lord Dhanvantari, regarded as the physician of the gods and the bringer of Ayurveda to the world, and it is considered auspicious to buy gold, silver, or new household items. Many families also light the year's first diya on this evening, the Yama Deepam, placed facing south at the doorstep as a prayer against untimely death.
Day 2: Naraka Chaturdashi (Choti Diwali)
This day marks Lord Krishna's defeat of the demon Narakasura, a story told in the Bhagavata Purana. The central ritual is the Abhyanga Snan, an oil massage followed by a bath, taken before sunrise. It is meant to cleanse the body as the story's victory cleansed the world of Narakasura's tyranny. In several South Indian and Maharashtrian homes, this, not the following night, is treated as the festival's defining day.
Day 3: Lakshmi Puja (Main Diwali)
This is the night most people mean when they say "Diwali." It falls on Amavasya, the new moon, of the Hindu month of Kartika. Two well-known stories are linked to this night.
The first is the return of Lord Rama, Sita, and Lakshmana to Ayodhya after fourteen years of exile and Rama's victory over Ravana, a homecoming widely described in the Valmiki Ramayana's Yuddha Kanda and later retold in Tulsidas's Ramcharitmanas. Tradition holds that the people of Ayodhya lit rows of earthen lamps to welcome them home on this very night, which is where the festival's association with light begins for many households.
The second is older still: the story of Samudra Manthan, the churning of the cosmic ocean, described in the Vishnu Purana, from which Goddess Lakshmi herself is said to have emerged. Worshipping her on this night is, in effect, inviting that same abundance into one's own home.
Goddess Lakshmi herself is first named as Shri in the Rig Veda's Shri Sukta, one of Hindu tradition's oldest hymns, making her among the most anciently attested deities still worshipped in Indian homes today.
ॐ श्रीं महालक्ष्म्यै नमः
Om Shreem Mahalakshmyai Namah
"Salutations to the great Goddess Lakshmi."
A widely used short invocation in Lakshmi Puja
Day 4: Govardhan Puja (Annakut)
This day recalls another story from Krishna's life: when the people of Vrindavan faced Indra's anger in the form of relentless rain, Krishna lifted the Govardhan hill on his little finger to shelter them, teaching that steady faith outlasts even a god's wrath. Families mark it with Annakut, literally a "mountain of food," a vast spread of vegetarian dishes offered in gratitude.
Day 5: Bhai Dooj
The festival closes with Bhai Dooj, sometimes called Bhaiya Dooj or Yama Dwitiya. Sisters apply tilak on their brothers' foreheads and pray for their long life, while brothers traditionally offer gifts in return. The day is linked to Yama, the god of death, and his sister Yamuna, whose affectionate welcome of her brother is said to be the origin of the custom.

Diwali: All Five Days, Your Muhurat
Calculated fresh for exactly where you are, not copied from a Delhi table
Each day is calculated from its own classical rule (Pradosh Kaal, Sthir Lagna, pre-dawn Tithi, Pratahkal, or Aparahna) using the Sun and Moon's actual positions for your location, per Dharmasindhu and Nirnaya Sindhu convention. A calculation aid, not a replacement for your family's tradition or purohit.
