As every year, many people are asking — “When is Diwali 2025? 20 October or 21 October?” Different sources are showing different dates, which has caused confusion. Let’s find out the actual date based on the Hindu Panchang, the Amavasya (new moon) tithi, and the Lakshmi Puja muhurat.
The link between Amavasya and Diwali
Diwali or Deepavali is celebrated on the Kartik Amavasya — the new moon day when the moon is not visible and the world is lit up with lamps. In 2025, Kartik Amavasya begins on 20 October 2025 (Monday) at 3:44 PM and continues until 21 October 2025 (Tuesday) at 5:54 PM.
According to religious tradition, the day when the Amavasya tithi is present at sunset is considered the day of Diwali. Therefore, this year the main Diwali / Lakshmi Puja will be observed on 20 October 2025.
Why Diwali will be celebrated on 20 October
- The Amavasya tithi begins on the afternoon of the 20th.
- Amavasya is present at sunset on the 20th, which is auspicious for Lakshmi Puja.
- Therefore astrologers and Panchangs recommend performing Lakshmi Puja on 20 October.
- Although the tithi continues until the evening of the 21st, some government calendars may show 21 October as a holiday — but the main worship is on the evening of the 20th.
