Which house list?

Same-sign Mars is house 1. The next sign is house 2; count forward around all twelve signs. The input must be sidereal, and the signs must come from the same chart.

What this comparison means

A listed house receives a positional flag under the selected convention. Three flags are possible because the tool repeats the same Mars placement from Lagna, the Moon, and Venus. A zero means none of these three checks places Mars in the selected house list; it is not a relationship prognosis.

Some published readings consider aspects, conjunctions, Mars’s condition, and cancellation rules. Four sign labels cannot establish those factors, so this result deliberately stops at the transparent house count. Read the rule history and worked example →
