The confusion surrounding the date for Diwali 2025 has been clarified, with authoritative sources confirming the main celebration will occur on October 20, 2025, despite the Amavasya Tithi spanning across both October 20 and 21. This clarification comes after extensive deliberation by religious authorities to resolve the scheduling conflict that had left many devotees uncertain about the proper observance day for the Festival of Lights. 
Diwali 2025 Date Confusion Resolved: Key Details for Celebration


The determination of the correct date for Diwali holds significant religious importance for millions of Hindus, Jains, and Sikhs worldwide who celebrate the victory of light over darkness, knowledge over ignorance, and good over evil.

The Astronomical Reason Behind the Confusion

The primary cause of the date confusion stems from the lunar calendar calculations central to Hindu festival scheduling. The Amavasya Tithi (new moon day), which determines the main day of Diwali, begins on October 20, 2025, at 3:44 PM and concludes on October 21, 2025, at 5:54 PM.
This year's rare celestial alignment created uncertainty about whether Diwali should be celebrated on October 20 or 21. According to astrologer Sidhharrth S Kumaar of NumroVani, "The reason for the confusion is that the current planetary transits are not very promising on a global level. If people continue to make mistakes, how can nature deliver justice? It is the way of nature to allow humankind to fall into the illusion of mistakes, and then bring about justice".

Official Resolution and Regional Considerations

After careful consideration of the astronomical factors and scriptural guidelines, multiple reliable sources including the Drik Panchang have confirmed that Diwali 2025 will be celebrated on October 20. The most auspicious time for Lakshmi Puja, the central ritual of Diwali, falls during the Pradosh Kaal on October 20 from 7:08 PM to 8:18 PM.
However, some regional variations may apply. According to astrological guidance, "Cities where the sunset occurs on or before 5:30 PM should celebrate on October 21. Cities where the sunset occurs after 5:30 PM should celebrate on October 20". This nuanced approach acknowledges the diversity of practices across different geographic locations.

The Complete Five-Day Diwali Festival Schedule

Diwali is not merely a one-day celebration but extends over five days of rituals, prayers, and festivities. Below is the complete schedule for Diwali 2025:
Date Festival Significance and Rituals
Saturday, October 18 Dhanteras Worship of Goddess Lakshmi and Lord Kuber; buying gold, silver, or utensils considered auspicious
Sunday, October 19 Narak Chaturdashi/Choti Diwali Commemorates Lord Krishna's victory over demon Narakasura; ritualistic oil bath before sunrise

Cultural and Spiritual Significance of Diwali

Diwali holds profound religious significance across different regions and communities. In North India, the festival primarily commemorates Lord Rama's return to Ayodhya after 14 years of exile and his victory over the demon king Ravana. The people of Ayodhya celebrated his homecoming by lighting countless diyas, a tradition continued today symbolizing the triumph of good over evil.
In South India, Diwali celebrates Lord Krishna's victory over the demon Narakasura. In Gujarat, the festival marks the end of the financial year, with Chopda Pujan (worship of account books) performed to invite prosperity. In Bengal and Odisha, Diwali coincides with Kali Puja, invoking the fierce form of Goddess Durga.
Beyond Hinduism, the festival holds importance for other faiths. Jains observe Diwali as the day when Lord Mahavira attained Nirvana, while Sikhs celebrate it as Bandi Chhor Divas, marking Guru Hargobind Ji's release from Mughal imprisonment.

Contemporary Celebrations and Environmental Considerations

Modern Diwali celebrations typically include illuminating homes with diyas and decorative lights, creating colorful rangoli designs, exchanging gifts and sweets among family and friends, and performing Lakshmi Puja to invite prosperity and wisdom.
In recent years, there has been growing emphasis on celebrating an environmentally sustainable Diwali. Many communities now advocate using eco-friendly diyas, natural rangoli colors, and green firecrackers to reduce pollution. The spiritual essence of the festival - focusing on inner light, knowledge, and family bonding - is increasingly emphasized over materialistic displays.
With the date confusion now resolved, devotees can prepare for the five-day festival that begins with Dhanteras on October 18 and culminates with Bhai Dooj on October 22, embracing the timeless message of light overcoming darkness that Diwali represents across cultures and communities.
