Yoga and Dosha Calculator
A free Vedic calculator that screens your birth chart for the classical yogas (planetary combinations) and doshas — from the Pancha Mahapurusha and Raja yogas to the Mangal and Kaal Sarpa checks.
A yoga is a specific combination of planets that the classical texts single out by name; a dosha is a placement the same texts flag for caution. Jagannatha Hora screens a birth chart against several hundred yogas and the common doshas at once, so you see which named combinations are actually present instead of checking each rule by hand.
Enter a birth date, time and place and the calculator lists every yoga it finds — Raja, Dhana, the five Pancha Mahapurusha yogas, Gaja Kesari and more — with the rule that forms each, alongside the Mangal (Manglik), Kaal Sarpa, Kemadruma and Pitra checks. The combinations are presented for an astrologer to weigh, never as a verdict.
How the classical yogas form
Every yoga has a precise, chart-independent rule. These are some of the best-known combinations and the placement that defines each — exactly the conditions the calculator tests, cited by their number in B.V. Raman's Three Hundred Important Combinations.
| # | Yoga (combination) | Forming rule from the chart |
|---|---|---|
| 1 | Gaja Kesari | Jupiter in a kendra (1st, 4th, 7th or 10th) from the Moon, not debilitated or combust (BVR-1). |
| 2 | Ruchaka (Mahapurusha) | Mars in Aries, Scorpio or Capricorn AND in a kendra from the Lagna (BVR-22). |
| 3 | Bhadra (Mahapurusha) | Mercury in Gemini or Virgo AND in a kendra from the Lagna (BVR-23). |
| 4 | Hamsa (Mahapurusha) | Jupiter in Cancer, Sagittarius or Pisces AND in a kendra from the Lagna (BVR-19). |
| 5 | Malavya (Mahapurusha) | Venus in Taurus, Libra or Pisces AND in a kendra from the Lagna (BVR-20). |
| 6 | Sasa (Mahapurusha) | Saturn in Capricorn, Aquarius or Libra AND in a kendra from the Lagna (BVR-21). |
| 7 | Budha-Aditya | The Sun and Mercury together in one sign (BVR-26). |
| 8 | Kemadruma | No planet other than the Sun beside the Moon (2nd/12th) and none in the kendras from the Lagna (BVR-5). |
Each yoga is read on its own, and several often apply to the same chart; the texts also weaken or cancel some by other placements. The calculator reports the combinations it detects for an astrologer to interpret — it does not predict outcomes.
Every yoga, named
Raja, Dhana, the five Pancha Mahapurusha yogas, Gaja Kesari, Budha-Aditya and more — each with the classical rule that forms it.
The main dosha checks
Mangal (Manglik), Kaal Sarpa, Kemadruma and Pitra — screened from the same chart, with the reason each is or is not flagged.
Grounded in the classics
Combinations are cited by their standard numbers from B.V. Raman's Three Hundred Important Combinations and read against BPHS and Phaladeepika.
Common questions
What is a yoga in Vedic astrology?
A yoga is a specific combination of planets that the classical texts single out by name — for example Gaja Kesari, Jupiter in a kendra from the Moon. It describes a computed placement, not a fixed outcome.
What is the difference between a yoga and a dosha?
Both are planetary patterns the texts name. A yoga usually marks a combination the texts describe as favourable; a dosha marks one they flag for caution, such as Mangal or Kaal Sarpa. This tool screens for both.
What are the Pancha Mahapurusha yogas?
Five yogas — Ruchaka, Bhadra, Hamsa, Malavya and Sasa — formed when Mars, Mercury, Jupiter, Venus or Saturn sits in its own or exaltation sign and in a kendra (1st, 4th, 7th or 10th) from the Lagna.
What is Manglik or Mangal dosha?
Mangal dosha is flagged when Mars occupies certain houses — commonly the 2nd, 4th, 7th, 8th or 12th — from the Lagna. The calculator applies the classical house rule and the standard exemptions.
Does this calculator predict my future?
No. It reports which classical combinations are present in the chart and the rule behind each. Interpreting them is the astrologer's work; the tool issues no prediction or verdict.
