Mangal dosha — also called Kuja dosha or Chevvai dosham — is the placement of Mars in the 1st, 2nd, 4th, 7th, 8th or 12th house of a birth chart. It is the single most consequential item in Vedic marriage matching, and the most misused. This checks it from all three reference points that traditional practice uses, and shows you the working.
The ascendant changes sign roughly every two hours, so this one genuinely needs an accurate birth time and place. Pick a city to fill the coordinates, or type them in — south and west are negative.

Why this one needs your birth place
The other calculators on this site read the Moon, which depends only on the moment. Mangal dosha is read primarily from the ascendant — the sign rising on the eastern horizon at birth — and that depends on where on Earth you were. The ascendant changes sign roughly every two hours, so an hour of error in the birth time, or a few hundred kilometres of error in the place, can genuinely change the answer.
If you do not have a reliable birth time, the Lagna row of the result is guesswork. The Moon and Venus rows are far more forgiving, and they are shown separately for exactly that reason.
The three reference points
Different schools count the six houses from different places, and this is the main reason two sites disagree about whether someone is Manglik:
- From the Lagna (ascendant) — the primary reading, used everywhere.
- From the Moon — standard across North and South India, and the one that survives an uncertain birth time.
- From Venus — used in South Indian practice, largely absent from North Indian practice.
A chart flagged from one reference and clear from the other two is a very different situation from one flagged by all three, and collapsing that into a single yes or no throws away the information that matters. This calculator refuses to do that.
The cancellations
Classical texts spend more words on cancelling Mangal dosha than on declaring it. That should tell you something about how the plain rule was meant to be used. The well-attested ones:
- Sign-specific nullification. Mars in Aries in the 1st, Gemini or Virgo in the 2nd, Aries or Scorpio in the 4th, Capricorn or Cancer in the 7th, Sagittarius or Pisces in the 8th, or Taurus or Libra in the 12th. In these combinations the dosha is treated as not arising at all.
- Mars in its own or exalted sign — Aries, Scorpio or Capricorn — is strongly mitigating.
- Jupiter conjunct or aspecting Mars, and by many authorities the Moon doing the same.
- Both partners carry the dosha, in which case it is treated as mutually cancelled. This is the most commonly applied cancellation of all.
- Age — several traditions hold that the effect lapses after the late twenties.
The calculator checks the first three from your chart and tells you which apply. The fourth needs both charts; the Guna Milan calculator is where a pair gets compared.
What this is worth, honestly
It is worth saying plainly, because a lot of sites will not. Mars occupies six of the twelve houses in the flagged set. Read from a single reference point that is already half of all charts before any refinement; read from three reference points and flagged if any of them hits, and the proportion climbs further still. A rule that catches most of the population is not identifying something rare.
That is the structural reason the classical literature attaches so many cancellations to it, and the reason experienced astrologers treat a bare Manglik finding as the beginning of an assessment rather than the end of one. The strength and dignity of Mars, what aspects it, the condition of the 7th house and its lord, and the running dasha all matter more than the bare placement.
Whatever the result here says, it is a statement about a chart under one traditional rule. It is not a statement about a person, a marriage, or anyone’s prospects, and it should not be used to make a decision about another human being.
Common questions
Is Mangal dosha the same as being Manglik?
Yes. Manglik, Mangalik, Kuja dosha and Chevvai dosham all name the same placement; the terms are regional.
Does the 2nd house count?
This is a genuine disagreement. Some traditions omit the 2nd, which measurably reduces how many charts are flagged. This calculator includes it, which is the more common convention, and names the house so you can see whether your result rests on it.
What if I do not know my birth time at all?
Read only the Moon and Venus rows and ignore the Lagna row. Use 12:00 as the time; the Moon moves about half a degree an hour, so it will usually still be in the right sign, while the ascendant will not be.
Does a high Guna Milan score cancel Mangal dosha?
No, and this is the most common misunderstanding. The two are independent checks. A 32-out-of-36 match with an uncancelled dosha on one side is exactly the case the tradition says to examine further, and the koot total says nothing about it.
