Mars in one of 6 houses, counted from three different points. Checkable — and cancelled more often than the pages selling remedies suggest.
Mangal dosha — "manglik" — is Mars in house 1, 2, 4, 7, 8 or 12. That is the whole rule, and it is why the answer is checkable rather than a matter of opinion.
Counted from where, though, is the part accounts disagree on. This site checks all three references the classical texts use — Lagna, Moon, Venus — and reports each separately, because a chart can be manglik from the Moon and not from the lagna, and a site that checks only one will tell you the opposite of a site that checks another.
| House | Counted from lagna | Also checked from |
|---|---|---|
| 1 | 1st | Moon and Venus |
| 2 | 2nd | Moon and Venus |
| 4 | 4th | Moon and Venus |
| 7 | 7th | Moon and Venus |
| 8 | 8th | Moon and Venus |
| 12 | 12th | Moon and Venus |
The rule above is where most pages stop. The texts also define conditions under which the dosha does not apply, and this site’s engine implements 16. These are its own labels, not a summary — a cancellation the calculator cannot actually detect has no business being listed as one:
| # | Cancellation |
|---|---|
| 1 | Mars in own sign |
| 2 | Mars exalted |
| 3 | Mars debilitated |
| 4 | Jupiter conjunction |
| 5 | Jupiter aspects Mars |
| 6 | Mars deeply combust by Sun |
| 7 | Mars in Lagna special signs |
| 8 | Mars in 4th in own sign |
| 9 | Mars in 7th special signs |
| 10 | Mars in 8th special signs |
| 11 | Mars in 12th special signs |
| 12 | Venus in Kendra |
| 13 | Mars is Yogakaraka |
| 14 | Mars at sandhi degrees |
| 15 | 7th lord in Kendra |
| 16 | Mars in 2nd in Mercury signs |
This matters more than the rule does. Being "manglik" is common, cancellation is common, and the combination means a raw yes from a calculator is not an answer — which is why the calculator on this site reports the cancellations it found rather than a verdict.
Mars in house 1, 2, 4, 7, 8 or 12. It is checked from the lagna, from the Moon and from Venus, and a chart can carry it from one reference and not another.
It depends only on where Mars sits, which needs your birth date, time and place. The free calculator gives the house from all three references and lists any cancellation that applies.
Often. This site’s engine checks 16 conditions — Mars in its own sign, exalted or debilitated, Jupiter conjunct or aspecting Mars, Venus in a kendra, Mars as yogakaraka, and others. A yes without the cancellations checked is half an answer.
The folk rule that two manglik charts cancel out is widely repeated. It is not among the conditions this site’s calculator checks, which are all about Mars’s own position and aspects in a single chart — so we will not tell you it applies. What to do about a marriage is a conversation, not a lookup.
Whether one is in yours is a question with a yes-or-no answer, and the chart is free to cast. What it means for you is the conversation.
