Kaal Sarp Dosh Calculator — Free Online

Kaal Sarp Dosh (काल सर्प दोष) is formed when all 7 classical planets — Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn — sit hemmed inside the 180° arc bounded by Rahu (north lunar node) and Ketu (south node). The chart looks like the planets are caught between the serpent's mouth and tail. Per Brihat Parashara Hora Shastra + Lal Kitab, this yoga can cause delays, struggle, sudden setbacks, and karmic obstacles — but also often produces deep spiritual breakthroughs after age 32-36.

12 types, named after the 12 serpent kings of Hindu mythology. The type is determined by which of the 12 houses Rahu occupies: 1=Anant, 2=Kulik, 3=Vasuki, 4=Shankhpal, 5=Padma, 6=Mahapadma, 7=Takshak, 8=Karkotak, 9=Shankhachud, 10=Ghatak, 11=Vishdhar, 12=Sheshnag. Each type affects a different life domain (self, wealth, marriage, career, etc).

Forward (Anuloma) Kaal Sarp = planets distributed CCW from Rahu to Ketu through the zodiac. Reverse (Pratiloma) = planets in the Ketu → Rahu half. Forward dosh is considered more karmic — past-life debts manifesting now. Reverse is considered more obstacle-oriented in the current life. Both qualify as "full" Kaal Sarp if all 7 planets fall inside the hemmed arc.

Yes but milder. When 5-6 of the 7 classical planets fall inside the Rahu-Ketu arc (with 1-2 outside), it is called partial or "loose" Kaal Sarp Yoga. Effects are diluted but still noticeable — periodic obstacles especially during Rahu/Ketu mahadasha or antardasha. Many classical astrologers still prescribe lighter Naga remedies for partial cases.

The flagship remedy is the Rahu-Ketu Shanti Puja at Sri Kalahasti Temple (Andhra Pradesh) — considered the most potent Kaal Sarp resolution site per shastra. Other major options: Narayan Nagbali at Trimbakeshwar (Nashik) — a 3-day ritual that simultaneously resolves Pitru Dosh; Naga Pratishtha at any Shiva temple; daily Maha Mrityunjaya japa; donating silver Naga-Nagin pair on Naga Panchami; reciting Rahu beej mantra 18,000 times in 40 days. All major remedies should be performed under a qualified pandit.

Planetary longitudes are computed via the Meeus simplified algorithm (~±0.5° accuracy for 1900-2100). Rahu / Ketu use the mean lunar node formula (~±0.3°). Ascendant (lagna) uses the standard LST + obliquity formula. House numbering uses whole-sign system (most common in Vedic astrology). Lahiri ayanamsa is applied. For ceremonial muhurat-grade precision, verify with a pandit running full Drik panchang ephemeris (Swiss Ephemeris or NASA JPL).

No. The classical texts repeatedly note that Kaal Sarp Yoga is a "yoga of karmic acceleration." Many famous spiritual masters, freedom fighters, and self-made tycoons had Kaal Sarp — they channelled the concentrated Rahu energy into focused, single-pointed achievement. The struggle phase typically lasts until 32-36 years, after which the same configuration often produces extraordinary spiritual depth, public influence, or sudden wealth (especially in 8th-house and 12th-house types).
