What is Mangal Dosha?
Mangal Dosha — also called Manglik dosha, and Kuja dosha in the south — is the placement of Mars in the 1st, 2nd, 4th, 7th, 8th or 12th house of a Vedic birth chart. Those six houses govern the body, the family one is born into, domestic peace, marriage, longevity and loss. Mars is the planet of heat, assertion and conflict, so classical texts read it there as friction carried into married life.
The dosha is descriptive, not a verdict. It describes a temperament the chart carries into a marriage, which is why the tradition also records so many conditions that soften or cancel it.
Which houses cause Mangal Dosha?
Houses 1, 2, 4, 7, 8 and 12. What differs between traditions is where you count them from:
- From the Lagna (ascendant) — the most widely used reference, describing the person and the body.
- From the Moon — the emotional mind, favoured in many northern and eastern traditions.
- From Venus — the significator of marriage and the spouse.
This calculator checks all three and shows each one separately, rather than returning a single yes or no. A chart afflicted from one reference is a different proposition from one afflicted from all three, and collapsing that into one word hides the thing that matters.
Partial (Anshik) versus full Manglik
Where Mars afflicts only one of the three references, the result is usually called Anshik Manglik — partial. Two references is generally read as a full Manglik chart, and three as a strong one. The distinction matters in matchmaking, where a partial dosha is routinely considered acceptable.
Does Mangal Dosha get cancelled?
Traditionally, yes, and often. The cancellation cited most is that when both partners are Manglik the dosha is mutually neutralised — which is why Mangal Dosha is checked on both charts during matchmaking rather than one. Others include Mars in its own sign or exaltation, Mars aspected by Jupiter, and various placements that vary by regional tradition.
If you are checking two charts against each other, the Kundli matching calculator runs the 36-point Ashtakoot Guna Milan and compares Mangal Dosha across both.
How this calculator works
Planetary positions come from the Swiss Ephemeris and are converted to sidereal longitudes with the Lahiri ayanamsha, the standard in Indian astrology. The ascendant is computed from your exact birth time and the latitude and longitude of your birth city, so an accurate time matters — the Lagna moves a full sign roughly every two hours.
