How this works

A Muhurat is an auspicious time window determined by the simultaneous quality of five Panchang elements: Tithi (lunar day), Vara (weekday), Nakshatra (lunar mansion), Yoga (luni-solar combination), and Karana (half-Tithi).

This calculator identifies time slots in the day that avoid inauspicious periods — Rahu Kaal, Yamaganda, and Gulika Kaal — and ranks the remaining windows by how many auspicious Panchang factors are active simultaneously.

The slot score is a weighted sum of active auspicious factors, normalised to [0, 1]. Higher-scored slots are shown first. The Abhijit Muhurat window (roughly 11:54 AM – 12:18 PM) is a midday exception that overrides some otherwise-blocked periods.

Demo data only. Panchang values shown here are fixed placeholders — not computed for your date or location. Real Tithi, Nakshatra, and inauspicious period timings require an astronomical ephemeris. Integration with Prokerala API or Swiss Ephemeris is planned for Phase 2.

Business opening Muhurat — what Jyotisha tradition considers

Starting a business (Vyapara Arambha) is treated as an auspicious new beginning in Jyotisha tradition. The Muhurat emphasises Vara (weekday), Nakshatra, and the avoidance of inauspicious periods, with Mercury (Budha) playing a prominent role.

Vara

Wednesday (Budha/Mercury — commerce and intellect) and Thursday (Guru/Jupiter — auspicious expansion) are widely cited as favourable Varas for business openings. Friday (Shukra/Venus) is also considered positive for trade in many traditions.

Nakshatra

Pushya, Rohini, Mrigashira, Uttara Phalguni, Hasta, Uttara Ashadha, and Uttara Bhadrapada are commonly cited across classical texts for business-related auspicious beginnings. Pushya is particularly associated with prosperity and growth.

Tithi

Shukla paksha is preferred. The 2nd, 3rd, 5th, 7th, 10th, 11th, and 13th Tithis are commonly considered auspicious for business commencements.

Inauspicious periods

Rahu Kaal, Yamaganda Kaal, Gulika Kaal, and Vishti (Bhadra) Karana are all avoided for business inaugurations.

What the calculator currently checks

The demo rule applied to Business Opening is the same illustrative rule used for all event types. Event-specific rules will be applied when Phase 2 Panchang integration is complete.

  • Avoids Rahu Kaal, Yamaganda Kaal, and Gulika Kaal
  • Treats Rohini Nakshatra as auspicious (broadly accepted convention)
  • Treats Vishti (Bhadra) Karana as inauspicious (broadly accepted convention)
  • Applies Abhijit Muhurat as a bonus positive factor
  • Requires a minimum window of 30 minutes
  • Does not yet differentiate Business Opening rules from other event types
