Muhurat

Muhurat (also spelled muhurta) is the practice of selecting the most favorable time for an important activity by evaluating multiple panchang factors simultaneously. A classical muhurat assessment considers the tithi, nakshatra, yoga, karana, and the rising sign (lagna), along with the positions of benefic and malefic planets. The goal is to find a time window where the maximum number of these factors align favorably for the specific activity in question.

Different activities have different muhurat criteria. A wedding muhurat emphasizes benefic nakshatras (Rohini, Mrigashira, Magha, Uttara Phalguni, Hasta, Swati, Anuradha, Moola, Uttarashada, Uttara Bhadrapada, Revati), avoidance of Vishti karana and Vaidhriti yoga, and a strong 7th house lagna. A griha pravesh (housewarming) prioritizes fixed nakshatras and a strong 4th house. Business inaugurations favor Labh choghadiya and the Siddhi or Amrita yogas.

Tithimala provides muhurat-relevant data by computing all five panchang elements using Swiss Ephemeris for any given moment and location. The astronomical engine calculates precise sunrise, the tithi active at sunrise, the current nakshatra and its remaining duration, the prevailing yoga and karana, and location-specific time windows like Rahu Kaal and choghadiya. Users can cross-reference these elements to identify favorable windows.

Historically, muhurat calculation was the exclusive domain of family jyotishis who maintained hand-computed ephemerides. Modern astronomical computation through libraries like Swiss Ephemeris has made this knowledge accessible to anyone, while maintaining the same mathematical rigor. The fundamental algorithms — sidereal longitude computation, ayanamsha application, sunrise determination — remain unchanged from their classical formulations in texts like the Surya Siddhanta.
