The seventh house is the area of a birth chart that speaks about marriage, business partnerships, and close one-to-one relationships. It sits opposite the ascendant, which makes it a mirror of how we relate to others. Understanding it can bring clarity to patterns you have noticed in love and cooperation.
A 7th House Calculator helps you find the sign on this cusp and any planets placed inside it. You only need your birth date, time, and location. Within seconds, you can see which sign rules your partnership sector and which planet acts as its ruler.
