When is Diwali 2025? Date, Puja Timings, Significance & Puja Guide

Diwali, or Deepavali, is observed across the Hindu world as the festival of lights — the victory of light over darkness and of dharma over adharma. In 2025 the main day falls on Monday, 20 October, the Amavasya of the Kartik month, when households light diyas, clean and decorate the home, and perform Deepavali Mahalakshmi Puja in the evening Pradosh Kaal.

The festival is not a single night. It stretches across five days from Dhanteras to Bhai Dooj, each with its own rite and story. Because the Amavasya tithi in 2025 begins on the afternoon of the 20th and ends on the afternoon of the 21st, some regional calendars differ on the preferred puja day; the notes below set out the tithi clearly so a devotee can decide with the local panchang in hand.

What follows is the date and muhurat for Diwali 2025, the five-day sequence, the classical legends behind the festival, and a practical guide to Mahalakshmi Puja as tradition prescribes it — without the padding of booking rails or product lists.

When is Diwali 2025?

According to the Hindu lunisolar calendar, the principal day of Diwali 2025 is Monday, 20 October 2025, Kartik Amavasya. The evening Lakshmi Puja is traditionally performed in Pradosh Kaal after sunset.

• Diwali 2025 date: Monday, 20 October 2025
• Lakshmi Puja muhurat (IST, indicative): 05:46 PM to 08:18 PM — Pradosh Kaal
• Amavasya tithi begins: 3:44 PM on 20 October 2025
• Amavasya tithi ends: 5:54 PM on 21 October 2025

Muhurat minutes shift with longitude and sunset. For the exact window at your own place, check the day’s panchang for your city rather than relying on a single national clock. Festival dates across the year are also listed on the house’s festival calendar.

Why some calendars show 20 October and others 21 October

Diwali is fixed on Kartik Amavasya. In 2025 that tithi begins in the afternoon of 20 October and runs into the afternoon of 21 October (IST). When a tithi straddles two civil dates, almanacs disagree on which evening the main Lakshmi Puja should fall.

Many North Indian and pan-Indian panchangs keep the principal Deepavali puja on the evening of 20 October, when the Amavasya is current through Pradosh Kaal. Some regional lists place the observance on the 21st. The sound practice is to follow the tithi and the local sunset muhurat of one’s own tradition, not a headline date alone. A month-by-month view of tithis is available on the tithi calendar.

The five days of Diwali 2025

Deepavali is a five-day arc. Each day carries a distinct observance:

Dhanteras is often joined, in household practice, with rites that seek the grace of wealth-deities; families who wish a formal homam on that theme look to the house’s finance and wealth homas, among them the Dhana Lakshmi Homam.

Significance and the legends of Diwali

Several classical narratives meet on Kartik Amavasya. None cancels the others; different regions emphasise different strands.

Return of Rama to Ayodhya. After fourteen years of exile and the defeat of Ravana, Rama, Sita and Lakshmana returned to Ayodhya. The citizens lit rows of lamps to welcome them. This Ramayana strand is the principal reason Diwali is kept as a festival of light in much of North India.

Emergence of Lakshmi. The Puranas place the appearance of Goddess Lakshmi from the Kshira Sagara, during the Samudra Manthan, on this Amavasya. From that association the evening is set aside for Deepavali Mahalakshmi Puja — not as a bargain for riches, but as the traditional worship of the deity of sri, order and sufficiency.

Krishna and Narakasura. In many Hindu homes the day before the main Amavasya — Naraka Chaturdashi — recalls Krishna’s slaying of Narakasura, read as freedom from arrogance and tamas. Vamana and Bali, and in some regions the coronation memory of Vikramaditya, add further layers of humility, just rule and dharma.

Astrologically the Amavasya is treated as a hinge between cycles: a night suited to quiet japa, lamp-lighting, and rites of shanti rather than to loud display alone.

Deepavali Mahalakshmi Puja — traditional method

The central household rite of Diwali evening is Mahalakshmi Puja, usually with Ganesha at the start of the altar. Tradition prescribes cleanliness, light, simple offerings and stotra — not elaborate spectacle.

Prepare the space. Sweep and wash the entrance and the puja room. A rangoli at the threshold and a row of oil diyas are customary. Place images or murtis of Lakshmi and Ganesha on a clean cloth over a low stool or peetha.

Samagri. Flowers, unbroken rice, turmeric, kumkum, incense, a lamp, fruits, sweets, a few coins or a small piece of metal, and water in a kalasha or cup are sufficient. Fresh cloth for the deities is used where the family keeps that custom.

Order of puja. After a brief sankalpa, Ganesha is honoured first. Lakshmi is then invited with avahana, offered arghya, flowers, naivedya and aarti. Many households recite the Shri Sukta, the Lakshmi Ashtottara, or the Mahalakshmi Ashtakam. Those who prefer a priest-led homam on the same stotra may request the Mahalakshmi Ashtakam Homam performed at the ashram and telecast live.

Timing. The preferred window is Pradosh Kaal on the Amavasya evening, after sunset and before the end of the stated muhurat. If the family cannot sit at that exact hour, the puja is still offered the same night with a sincere sankalpa; the tithi matters more than the minute.

How families keep the five days with meaning

Fireworks and shopping are recent outer forms. The older discipline of the week is simpler:

• Begin Dhanteras or Chhoti Diwali with a thorough cleaning of the house and an oil bath where that is the family custom.
• Light a Yama Deepam at the main door on Dhanteras evening, as many almanacs prescribe, as a prayer against untimely harm.
• On the main night, keep the Mahalakshmi Puja unhurried; involve children in placing diyas rather than only in crackers.
• On Govardhan / Annakut, offer a share of cooked food in gratitude before the family eats.
• On Bhai Dooj, keep the tilak and aarti even if brother and sister live in different cities; the rite is the bond, not the feast alone.
• Dana — food, clothes or money given quietly to someone in need — is classically joined to Lakshmi worship across the five days.

For a suitable hour for any of these acts, the muhurat finder can narrow the day’s auspicious windows. The house performs the rites at its Yagna Ashram in Pollachi, Coimbatore District, with live telecast to devotees wherever they live; there are no walk-in branches. Yantra Pujas are performed in our consecrated sanctum.
