What is Mangal Dosha (Manglik)?

Mangal Dosha — being manglik, also Kuja Dosha or Chevvai Dosham — is a classical flag raised when Mangala (Mars) falls in particular houses of a kundali. It is a statement about a placement, and the rule defining it is far less uniform than the term’s reputation suggests.

The rule

The common form counts houses from the lagna and flags Mangala in the 1st, 4th, 7th, 8th or 12th. Because houses are counted from the lagna, the flag depends on the birth time as much as on Mars: the same day in the same city, two hours apart, can give opposite answers. This site applies exactly that rule, from the lagna, and names it rather than presenting it as the only one.

Traditions disagree, and that matters

Some traditions count the same houses from the Moon or from Shukra instead of the lagna; some include the 2nd house; southern practice differs from northern. A chart can therefore be manglik under one convention and clean under another — the single most important thing to know about the term. A tool that reports it without naming its reference point has hidden a choice, not removed one.

What a computation can and cannot settle

Whether Mangala sits in a given house at a given moment is arithmetic, and this site will compute it. Whether that constitutes an obstacle, and what if anything should follow, is interpretation — traditionally a matter for a family astrologer, not something a calculator decides. The classical texts themselves list numerous cancellations (parihara) under which the flag is held not to apply.
