Mangal Dosha (Sanskrit mangal for Mars + dosha for flaw or affliction) is one of the most widely cited compatibility checks in Indian matrimonial astrology. The simplified screening rule examines where Mars sits in your sidereal birth chart relative to three reference points: Lagna (your ascendant, the sign rising on the eastern horizon at birth), the Moon (your Janma Rashi sign), and Venus.
If Mars sits in any of houses 1, 2, 4, 7, 8, or 12 as counted from any of those three reference points, the chart is flagged Manglik. The reasoning in classical sources treats Mars as a fierce planet (krura graha) whose presence in those houses traditionally signifies friction in marriage and relationships. Classical Vedic astrology then layers cancellation rules on top of the basic check - the cancellation list below summarizes the four most commonly cited.
The terms below refer to the same astrological phenomenon - Mars in afflicting houses from Lagna, Moon, or Venus - across different Indian languages and regional matrimonial vocabularies. The chart analysis is identical; only the term differs.
| Language / Region | Term | Etymology |
|---|---|---|
| Sanskrit / Hindi (pan-Indian) | Mangal Dosha | Mangal = Mars; Dosha = flaw / affliction |
| Hindi (matrimonial vernacular) | Manglik Dosha | Manglik = person affected by Mangal Dosha |
| Telugu, Kannada | Kuja Dosha | Kuja = Mars in Telugu / Kannada |
| Tamil | Chevvai / Sevvai Dosham | Chevvai = Mars in Tamil; spelling varies by script |
| North Indian / schwa-deleted | Mangal Dosh | Mangal Dosha without the final “a” vowel |
The tool runs through three identical checks, one per reference point:
For each reference, if the resulting house number is 1, 2, 4, 7, 8, or 12, the reference “afflicts”. The tool then reports how many of the three afflict (0 to 3) and whether the overall chart is flagged. The whole-sign formula:house = ((Mars sign minus reference sign + 12) mod 12) + 1.
The 6 afflicting houses (1, 2, 4, 7, 8, 12) come from Brihat Parashara Hora Shastra with some traditions excluding house 2; this tool includes house 2 per common South Asian matrimonial convention. The 3 reference points (Lagna, Moon, Venus) follow the standard B.V. Raman + Muhurta Chintamani framing.
The verdict card shows two pieces of information in order of importance. First, the raw reference count - how many of Lagna, Moon, Venus afflict (out of 3). This is the deterministic, classically-grounded measurement. Second, a severity heuristic label (mild / moderate / severe) that translates the raw count for quick reading.
| Raw reference count | Severity (this tool) | Manglik? |
|---|---|---|
| 0 of 3 | None | No |
| 1 of 3 | Mild | Yes |
| 2 of 3 | Moderate | Yes |
| 3 of 3 | Severe | Yes |
The mild / moderate / severe scale is a tool-internal descriptor, not a classical determination. Classical Vedic astrology does not standardize an intensity scale, and different practitioners assign Lagna more weight than Moon or Venus or weight by specific house. Treat the raw count as primary, the label as secondary.
The simplified Mangal Dosha check flags Mars in any of 6 houses (1, 2, 4, 7, 8, 12) from each of 3 reference points (Lagna, Moon, Venus). For any single reference point, Mars falls in an afflicting house with probability 6 out of 12 = 1/2. Under the simplified rule that any one reference point afflicting suffices to flag the chart, the probability of NOT being flagged is (6/12)3 = 1/8, so the model predicts roughly 7 in 8 charts (about 85-90%) get flagged. This uniform sign-model baseline (87.5%) is the floor; real Lagna, Moon, and Venus distributions are not perfectly uniform across signs, but the conclusion is the same: about 85-90% of random Indian birth charts flag as Manglik under the simplified 3-reference six-house rule.
Classical Vedic astrology applies four cancellation rules that the simplified check ignores:
Some practitioners also discount Manglik flags after age 28. This is a popular practitioner belief that varies by tradition - it is NOT a classical Vedic cancellation rule and is treated separately from the four rules above. Different schools differ on whether age cancels the dosha at all.
This v1 tool does NOT apply any of these cancellation rules. A Manglik flag here is a starting screening result, suitable as a conversation-starter for further consultation with a Vedic astrologer, NOT as a final matrimonial verdict.
In matrimonial practice, Mangal Dosha is one of several compatibility checks layered alongside the 36-point Ashtakoot Guna Milan framework. A typical reading combines: (a) the Manglik check on each partner’s chart, (b) any classical cancellations (own sign, exaltation, benefic aspect, mutual Manglik), and (c) the Guna Milan score and individual Koot strengths.
For the full 36-Guna Ashtakoot Guna Milan analysis, see our Kundli Matching tool which computes the 8-Koot compatibility score from both partners’ birth details and flags any Bhakoot or Nadi dosha at the same time.
Mangal Dosha (also called Manglik Dosha, Kuja Dosha in Telugu / Kannada, or Chevvai Dosham / Sevvai Dosham in Tamil) refers to the placement of Mars in houses 1, 2, 4, 7, 8, or 12 as measured from three reference points in your birth chart: Lagna (Ascendant), the Moon, and Venus. If Mars sits in any of these houses from any of the three references under the simplified screening rule, the chart is flagged Manglik. The Sanskrit word Mangal means Mars; dosha means flaw or affliction.
Under this v1 simplified screening rule, yes. The tool flags a chart Manglik when Mars sits in one of houses 1, 2, 4, 7, 8, or 12 from Lagna, the Moon, or Venus. The raw reference-point count above the verdict tells you how many of the three references afflict (out of 3), and the severity heuristic labels that count (mild / moderate / severe). However, classical Vedic astrology applies several cancellation rules that this v1 does not compute - see the cancellation section above for the list.
For non-boundary charts using the same Lahiri sidereal ayanamsa and whole-sign house rule, raw Mars house numbers should generally match across Vedic engines (AstroSage, Drik Panchang, prokerala). Investigate when the chart sits near a sign boundary for any of Lagna, Mars, Moon, or Venus - small ephemeris differences can flip the house - or when a calculator applies bhava-style house computation or cancellation-adjusted verdicts. Where this tool differs from competitors is the post-cancellation verdict: AstroSage and Drik both apply classical and intensity rules to soften the final flag, while this v1 returns the raw simplified screen. The raw output here is more honest about WHICH cells are afflicted; their final verdict carries more interpretation. Use this tool as a starting screening result and consult a qualified astrologer for the full interpretation.
They refer to the same phenomenon in different Indian languages. Mangal Dosha is the Sanskrit / Hindi term (Mangal = Mars). Chevvai Dosham (also Sevvai Dosham) is the Tamil term (Chevvai = Mars). Kuja Dosha is the Telugu / Kannada term (Kuja = Mars). All three describe Mars sitting in one of the 6 afflicting houses from Lagna, Moon, or Venus. The underlying chart analysis is identical; only the language and regional matrimonial context differs.
Classical Vedic astrology lists four cancellation rules: (1) Mars in its own sign (Aries or Scorpio), (2) Mars in exaltation (Capricorn), (3) Mars receiving an aspect from Jupiter or Venus, (4) both partners having Mangal Dosha (mutual Manglik). Some practitioners also discount Manglik flags after age 28 - this is a popular belief that varies by tradition, NOT a classical cancellation rule. This v1 tool does NOT compute any of these cancellations; the flag here is a starting screening result for further consultation with a Vedic astrologer.
Under the simplified 3-reference six-house rule, roughly 7 in 8 charts (about 85-90%) get flagged Manglik because the union of 'Mars in any of 6 houses out of 12, from any of 3 references' is a very large event space. Exact sign-model math under uniform sign assumption: 1 minus (6/12)^3 = 87.5%. The high base rate is the strongest argument for paying close attention to the cancellation rules (which this v1 does not apply) and for consulting an astrologer rather than treating the raw flag as a final verdict.
No. The raw Manglik flag in matrimonial contexts is a screening signal, not a prohibition. About 85-90% of charts flag under the simplified rule, classical cancellations apply to many of those, and the same-side mutual-Manglik convention itself cancels Manglik when both partners are flagged. The cultural framing varies by region and family; consult a qualified astrologer for the specific reading of any chart before drawing conclusions about marriage compatibility.
Mangal Dosha and Manglik Dosha refer to the same condition; the terms are used interchangeably in Hindi and Sanskrit matrimonial vocabulary. Manglik is the adjective form (a person affected by Mangal Dosha is called Manglik). North Indian matrimonial sites tend to use Manglik more often; classical Vedic texts use Mangal Dosha. There is no analytical difference between the two terms.
For each of the three reference points (Lagna sign, Moon's sign, Venus's sign), the tool counts Mars's whole-sign house from that reference. A whole-sign house is computed as ((Mars sign minus reference sign + 12) mod 12) plus 1, giving a value 1 through 12. If that house number is 1, 2, 4, 7, 8, or 12, the reference 'afflicts'. The chart is flagged Manglik if Mars afflicts from any of the three references. The 'raw reference count' field in the verdict shows how many of the three afflict (0, 1, 2, or 3).
This is a tool-internal heuristic, not a classical scale. We label 1 of 3 reference points afflict as mild, 2 of 3 as moderate, and 3 of 3 as severe. Classical Vedic astrology does not standardize an intensity scale, and different practitioners weight Lagna more heavily than Moon or Venus or apply intensity scales based on house number specifically. The raw reference count above the verdict is the primary signal; the mild / moderate / severe label is a secondary descriptor for quick reading, not a classical determination.
