Every year, Diwali brings with it a sense of warmth, light, and new beginnings. It is that one evening when homes across India glow with diyas, families gather for prayer, and the air feels charged with hope. Yet one detail makes all the difference between a good Diwali and a truly auspicious one: the Lakshmi Puja Muhurat. In 2025, Diwali will fall either on October 20 or October 21, depending on your city’s sunset time. It sounds like a small detail, but according to Vedic astrology, it changes everything.

When is Diwali 2025 in India?

The festival will be celebrated on October 20 in most parts of India, including Delhi, Mumbai, Bengaluru, Chennai, Hyderabad, and Ahmedabad, and on October 21 in eastern regions like Kolkata, Patna, Ranchi, and Dibrugarh.

This difference follows a sacred astrological principle: Lakshmi Puja should be performed when Amavasya Tithi (the new moon) and Pradosh Kaal (the twilight period just after sunset) coincide. If sunset occurs before 5:30 pm, the Puja is performed that same evening. If sunset occurs after 5:30 pm, the auspicious period shifts to the following day. That’s why the eastern states, where sunset happens earlier, will celebrate on October 21, while the rest of India will perform Lakshmi Puja on October 20, 2025.

Understanding the Diwali Muhurat

The most auspicious time to perform Lakshmi Puja is during Pradosh Kaal, the sacred window that begins just after sunset and lasts for about two hours. When Amavasya Tithi overlaps with this time, it becomes the most powerful period to invite Goddess Lakshmi into one’s home. his phase aligns with Vrishabha Lagna, ruled by Venus, the planet of beauty, wealth, and harmony. Worshipping Goddess Lakshmi during this Lagna is said to attract prosperity, peace, and stability to both home and heart.

For most cities across India, Amavasya Tithi coincides with Pradosh Kaal on October 20, making it the ideal day for Lakshmi Puja. The auspicious time for worship will be between 5:46 pm and 8:18 pm on October 20, 2025.

In Kolkata, Patna, and Dibrugarh, however, Amavasya Tithi extends through Pradosh Kaal on both October 20 and 21. According to Dharmasindhu and other classical astrological texts, when this overlap occurs, the second day is chosen for performing the Lakshmi Puja. Therefore, in eastern India, October 21 will be observed as the day of Lakshmi Puja, with the auspicious window between 5:46 pm and 8:18 pm.**

These overlapping periods of Pradosh Kaal and Vrishabha Lagna form the perfect alignment for Lakshmi Puja 2025, symbolising the union of divine timing and cosmic harmony.

Why the Sunset Timing Matters

In Vedic astrology, every ritual is aligned with planetary and lunar movement. The transition between daylight and night is considered spiritually potent because it balances solar and lunar energies. When Amavasya coincides with this time, the symbolic darkness of the night represents a clean slate: a perfect time for calling in prosperity and letting go of negativity. Lighting diyas after sunset is not only symbolic but also scientifically linked with balancing natural bio-rhythms and promoting calmness. In simple terms, lighting lamps at the right moment allows you to align your home’s energy with the cosmic rhythm.
