What is Muhurta in Vedic astrology?

Muhurta is the Vedic science of selecting an auspicious date and time for important activities such as marriage, housewarming, travel, or starting a business. It considers multiple factors including Tithi, Nakshatra, Yoga, planetary positions, and the individual's birth chart to find the most favourable window for success.

How does the AI Muhurta finder work?

Our Muhurta engine is a classical constraint-based system with 36 rules from 7 texts (Muhurta Chintamani, Dharma Sindhu, BPHS, Brihat Samhita, Prashna Marga, B.V. Raman, Kalaprakashika). Unlike scoring-only systems, it rejects on fatal flaws first: Ganda/Vyatipata/Vaidhriti yogas are absolute vetoes for samskaras, Dagdha Tithi and Nakshatra Gandanta block windows outright. Only after passing these hard filters does scoring apply. The 5-tier cancellation hierarchy ensures strong lagna can cancel minor defects (weak karana, dur muhurtam) but CANNOT override inauspicious yoga or dagdha tithi – matching classical practice where one fatal dosha invalidates an otherwise good muhurta. Each activity has classically verified nakshatra whitelists (not permissive "everything not forbidden" lists). With birth data, the engine adds Tara Bala (3-cycle degradation), Chandra Bala (with Ashtama Chandra penalty), and Dasha Harmony.

Which activities are supported by the Muhurta AI tool?

Dekho Panchang's Muhurta AI supports 20 activities including marriage, housewarming (Griha Pravesh), travel, vehicle purchase, business launch, property purchase, naming ceremony, education start, medical procedures, job joining, gold purchase, loan signing, court hearings, and more. Each activity has specific Vedic rules that the AI applies automatically.

Which ayanamsha does the Muhurta AI use for scoring?

The Muhurta AI always uses Lahiri (Chitrapaksha) ayanamsha for scoring, regardless of your kundali ayanamsha preference. This is because all classical muhurta rule tables – from Muhurta Chintamani, Dharma Sindhu, and Prashna Marga – were composed using Lahiri nakshatra boundaries. Applying those rules with a different ayanamsha (KP, Raman) would shift the boundaries and produce less accurate results. Your birth chart and panchang pages still use your chosen ayanamsha for display.

How does the AI Muhurta engine differ from other panchang sites?

Most panchang sites use binary pass/fail on Panchanga Shuddhi – a date either passes or fails. Dekho Panchang's 36-rule engine scores windows 0-100 with classical cancellation logic from Muhurta Chintamani Ch.7: a strong lagna genuinely cancels a weak karana, not just offsets it numerically. We also personalise scores using your birth chart (Tara Bala, Chandra Bala, Dasha Harmony) and explain each recommendation with chapter-level citations – like a classically trained Jyotishi.

Is the Muhurta AI free to use?

Yes, completely free. The Muhurta AI scanner, all 20 activities, personalised scoring, and classical reasoning chains are available without any paywall or signup. We believe Jyotish Shastra should be accessible to everyone.

What is Muhurta – The Vedic Science of Auspicious Timing

Muhurta (electional astrology) is the branch of Jyotish Shastra dedicated to selecting the most favourable moment for initiating important actions. The foundational principle is simple yet profound: time is not neutral. The Vedic tradition holds that Kaal (Time) is the supreme force – every moment carries a unique energetic signature shaped by the positions of the Sun, Moon, and planets. A marriage begun under an auspicious muhurta inherits the cosmic support of that moment; a business launched during Vishti Karana or Rahu Kaal inherits their obstruction.

The Five Elements of Muhurta (Panchanga Shuddhi)

A muhurta is evaluated through five simultaneous lenses, collectively called Panchanga Shuddhi. Tithi (lunar day) – each of the 30 tithis per month has a ruling deity and intrinsic quality. Nanda tithis (1, 6, 11) favour joyful occasions; Bhadra tithis (2, 7, 12) suit prosperity-oriented acts. Nakshatra (lunar mansion) – the 27 nakshatras are classified as Fixed, Movable, Sharp, Soft, or Mixed, each suited to different activities. Deva nakshatras like Pushya and Revati are universally auspicious. Yoga – the 27 nitya yogas arise from the combined longitude of Sun and Moon. Siddhi, Amrita, and Shubha yogas amplify success; Vyatipata and Vaidhriti are avoided. Karana (half-tithi) – 11 karanas rotate through each lunar month. Vishti (Bhadra) karana is universally inauspicious. Vara (weekday) – each day is ruled by a graha. Thursday (Guru) and Friday (Shukra) are broadly favourable; Saturday and Tuesday require careful evaluation.

Classical Scriptural Basis

The primary texts for muhurta selection are the Muhurta Chintamani by Rama Daivagya and the Muhurta Martanda by Narayana Daivagya. These 16th-17th century treatises codify rules from earlier sources including the Brihat Samhita of Varahamihira and the Kalaprakashika. They define specific conditions for each type of activity – marriage requires a fixed nakshatra on a Monday, Wednesday, Thursday, or Friday with Shukla Paksha tithi, for instance – and enumerate hundreds of special yogas (Sarvartha Siddhi, Amrita Siddhi, Ravi Yoga) that enhance or diminish a window.

Classical 36-Rule Scoring Engine

Our engine applies 36 discrete rules sourced from 7 classical texts: Muhurta Chintamani (MC), Dharma Sindhu, BPHS, Brihat Samhita, Prashna Marga, B.V. Raman's Muhurtha, and Kalaprakashika. Rules are organised into a 5-tier authority system: (1) Absolute vetoes – Venus/Jupiter combustion, Adhika Masa, Chaturmas with exact Devshayani→Prabodhini Ekadashi boundaries; (2) Override rules – Godhuli Lagna (sunset ±24 min) overrides all defects for marriage per Brihat Samhita Ch.103, and Venus/Mercury/Jupiter in the ascendant cancels all other flaws per MC Ch.7; (3) Major factors – nakshatra suitability, tithi-vara alignment, 8th house vacancy; (4) Standard scoring – yoga, karana, hora lord, choghadiya; (5) Cancellable factors – weak karana or minor dosha that a strong lagna compensates. This is classical cancellation logic, not additive scoring: a powerful lagna genuinely removes defects rather than merely offsetting them numerically. When birth data is provided, the engine adds personalised dimensions: Tara Bala (nakshatra compatibility), Chandra Bala (Moon transit strength), and Dasha Harmony (current Vimshottari period alignment). Each scored window shows pandit-style reasoning with chapter-level citations.

What Makes a Good Muhurta

A well-chosen muhurta requires both the presence of auspicious factors and the verified absence of inauspicious periods. The engine detects: Dur Muhurtam (the 48-minute daily window that shifts by weekday), Varjyam (nakshatra-specific inauspicious ghatis), Tithi-Gandanthara (junctional tithis at paksha boundaries), Rahu Kaal and Yamaghanda, Vishti Karana (Bhadra), Panchaka dosha (Moon in nakshatras 23-27), Venus/Jupiter combustion with BPHS-standard orbs (Venus 10°, 8° retrograde; Jupiter 11°), exact Chaturmas boundaries computed from real Devshayani and Prabodhini Ekadashi dates (not month approximations), and 8th house vacancy check for marriage. Unlike binary pass/fail systems, our engine grades windows 0-100 with differentiated reasoning – a window during Rahu Kaal with perfect lagna and excellent nakshatra will score differently from one with multiple minor flaws, because the cancellation hierarchy (MC Ch.7: "strong lagna removes all defects") genuinely elevates certain combinations above their individual components.

How We Calculate

Our scoring engine applies 36 discrete rules from 7 authoritative texts: Muhurta Chintamani (Ch. 6-7, Vivah/Lagna Prakarana), Dharma Sindhu (Chaturmas/Adhika Masa prohibitions), BPHS (combustion orbs), Brihat Samhita (Ch. 103, Godhuli Lagna), Prashna Marga, B.V. Raman's Muhurtha, and Kalaprakashika. Every rule traces to a specific chapter or verse.

Hard Prohibitions (Absolute Vetoes)

✗Venus/Jupiter combustion – BPHS standard orbs: Venus 10° (8° retro), Jupiter 11°. We follow the classical 10° standard.
✗Adhika Masa – Dharmasindhu: samskaras prohibited in intercalary months.
✗Chaturmas – Dharmasindhu: marriage/griha pravesh prohibited Shravana through Ashwina.
✗Kharmas – marriage prohibited when Sun is in Dhanu (Sagittarius) or Mina (Pisces).
✗Forbidden nakshatras – per Muhurta Chintamani + Jyotirnibandha: activity-specific.

5-Tier Cancellation Logic

This is not binary pass/fail. After hard prohibitions (Tier 1), remaining days are scored via a 5-tier authority hierarchy. Override rules (Tier 2) – Godhuli Lagna (sunset +/-24 min, Brihat Samhita Ch.103) or Venus/Mercury/Jupiter in lagna (MC Ch.7) – genuinely cancel all lower-tier defects. Major factors (Tier 3) include nakshatra, tithi-vara alignment, 8th house vacancy. Standard (Tier 4) covers yoga, karana, hora, choghadiya. Cancellable (Tier 5) – weak karana that a strong lagna compensates.

72+ = Excellent58-71 = Good50-57 = Fair

Activity-Specific Rules

Classical texts prescribe different rules for each samskara. Marriage is the strictest (all 7 restrictions apply). Mundan requires Uttarayana (MC Chudakarana Prakarana). Namakarana is time-bound – period-level restrictions do not apply. Each activity has a specific nakshatra list sourced from classical texts. Time windows are scored at 15-minute granularity for precision.

15-Minute Precision

The engine divides each day into 15-minute windows and scores each independently. This means scores on the same day can differ by 30+ points between 6:00 AM and 10:00 AM – because hora lord, choghadiya, and lagna change continuously. Each scored window shows factor-by-factor analysis with chapter-level citations.
