Mangal Dosha, also called Kuja Dosha or Bhauma Dosha, is a named astrological condition associated with Mars’s position in a natal chart. Public calculators commonly test Mars from the Lagna, Moon, and Venus. Our free house-position calculator lets you enter all four sidereal D1 signs and shows the count from each reference point. It reports the chosen rule, not a prediction about a person’s life or marriage.
Three published house lists
| Choice | Counted houses | Difference |
|---|---|---|
| Combined | 1, 2, 4, 7, 8, 12 | Includes both house 1 and 2 |
| North convention | 1, 4, 7, 8, 12 | Omits house 2 |
| South convention | 2, 4, 7, 8, 12 | Omits house 1 |
Drik Panchang’s Mangal Dosha page explicitly describes this North/South difference and says that its own calculator checks both houses. These are its descriptions of regional conventions, not a claim that every practitioner in either region agrees. Our menu mirrors those three lists so a comparison is reproducible.
How whole-sign counting works
Start the count at the reference sign: it is house 1. Move one sign forward in zodiac order for house 2, continuing through 12 and wrapping from Pisces to Aries. For example, if Lagna is Aries and Mars is Taurus, Mars is house 2 from Lagna. The combined and South lists flag that Lagna row; the North list does not. If the Moon is Taurus, Mars is house 1 from the Moon and the result flips: combined and North flag the Moon row, while South does not.
This tool counts whole rāśis. A bhāva-cusp chart can assign a planet to a different house near a cusp, and a rounded sign label cannot communicate that distinction. It does not compute planetary longitudes, a birth time, or a local ascendant; the user supplies all four signs from one sidereal chart. Changing an ayanamsa near a 30° sign boundary can change a label.
What an older textual witness says
Chapter 80, verse 47 of the Bṛhat Pārāśara Horā Śāstra names Mars in the ascendant, fourth, seventh, eighth, or twelfth, with a condition concerning benefic aspect or conjunction. That passage appears in a chapter on female nativities and carries a severe historical marriage claim. It does not by itself establish the modern six-house rule, the separate Moon and Venus checks, or a valid prediction. We cite it to show the difference between a textual witness and today’s broader calculator convention.
Why a sign-only result is limited
Published interpretations may add cancellation conditions, planetary aspects, conjunctions, the strength of Mars, and comparison with another chart. We calculate none of these. We also do not use Drik Panchang’s approximate percentage table, because its values and relationship claims are not measurements. This page presents a transparent position check for study and cross-checking, not marriage advice.
To prepare inputs, draw a Vedic birth chart with a recorded time, place, and ayanamsa. Copy its sidereal D1 Lagna, Moon, Venus, and Mars signs. The Rashi and Lagna lookup can help with two labels, but does not supply Mars and Venus. Record your original chart settings if you compare calculators.
Frequently asked questions
Is house 1 the same sign as Lagna?
Yes in this whole-sign calculation. Lagna’s own rāśi is counted as the first house; the sign after it is second.
Why do I get one or more matches?
Each of Lagna, Moon, and Venus starts a new count. The same Mars sign may fall in a listed house from one reference but not from another. The display shows all three rows instead of hiding the difference behind a single label.
Is a match a fixed judgment?
No. It states that a house number appears in the selected list. Other traditional rules and human circumstances are outside this input and cannot be inferred from it.
