Why is Rahu Kalam avoided for Satyanarayan Puja?

Rahu Kalam is considered an inauspicious period ruled by the shadow planet Rahu. For Satyanarayan Puja, the evening window (5-8 PM) is preferred, and dates where Rahu Kalam overlaps this window receive a scoring penalty.

How are the puja dates calculated?

Dates are calculated using the ancient Surya Siddhanta astronomical algorithm, which determines tithi (lunar day) at sunrise based on the precise positions of the Sun and Moon. This method has been used in Hindu calendars for over 1500 years.

✨ Cosmic Timing Insight

Satyanarayan Puja is ideally performed during Purnima (Full Moon) — a time of completion, gratitude, and divine abundance. Ekadashi offers a powerful window for spiritual focus and devotion. Thursdays, ruled by Jupiter (Guru), amplify the blessings of this sacred observance. The evening window of 5–8 PM is the preferred puja time.

Best: Purnima Evening Great: Ekadashi Good: Any Thursday Avoid: Rahu Kalam overlap

Frequently Asked Questions

Which tithi is most auspicious for Satyanarayan Puja?

Purnima (Full Moon) is universally regarded as the most auspicious tithi. It symbolizes completeness, divine grace, and abundance. Ekadashi is the next best choice, especially for those seeking spiritual growth and inner purification.

Why does Rahu Kalam matter for the puja?

Rahu Kalam is a daily 90-minute window considered inauspicious for sacred activities. Our calculator checks whether Rahu Kalam overlaps the preferred evening puja window (5–8 PM) and adjusts the recommendation accordingly.

How accurate are these Panchanga calculations?

Our calculations use the Surya Siddhanta algorithm — one of the oldest and most respected astronomical texts, dating back over 1,500 years. Tithi is determined precisely at sunrise for your selected location, ensuring accurate lunar-day assignment.

Can I perform the puja on any date not listed here?

Yes. While Purnima and Ekadashi are the most recommended, Satyanarayan Puja can be performed on any day with sincere devotion. Our tool helps you identify the most cosmically aligned dates for maximum spiritual benefit.

Calculation Methodology

All dates are computed using the Surya Siddhanta astronomical model — calculating solar and lunar longitudes, tithi at sunrise, and Rahu Kalam based on precise sunrise/sunset times for your geographic coordinates. This system has guided Hindu calendar-making for millennia.
