The partnership house
The 7th house covers one-to-one ties: a spouse, a business partner, a regular client, and people you oppose in the open. The sign on the cusp is the Descendant, opposite your rising sign. It describes the style of those meetings, and the traits you tend to hand to the other person. Planets in the house bring their own topics into that room. The rest of the natal chart shows how the cusp sits with your Sun, Moon, and Venus.
Why the birth time matters
The 7th house cusp is taken from the local horizon at your birth place, in the Placidus system. It needs the date, the clock time, and the city. The Ascendant moves about one degree every four minutes, so a wrong time moves the cusp, and near the edge of a sign it can change the sign. If the time is unknown, noon is only a stand-in. The rising sign itself is on the rising sign calculator.
Frequently asked questions
What does the 7th house say about relationships?
The 7th house is one-to-one contact: a spouse, a committed partner, a client, a co-signer, and an open opponent. The sign on the cusp is your Descendant, opposite the Ascendant. Planets in the house name what you deal with there, on top of the cusp sign.
Why does this calculator need my birth time?
House cusps follow the horizon, and the horizon turns with the Earth. An hour off can put the 7th cusp in another sign, especially if you were born near a sign change. When the time is missing, the calculator uses noon, and that result is only approximate.
Is the 7th house only about romance?
Romance and marriage sit here, and so do contracts, one-to-one clients, and legal opponents. It is the house of the other person you face directly. Venus still describes how you love. The 7th house describes the setting those meetings happen in. Compatibility compares two charts.
