House Calculator

The House Calculator divides your birth chart into the twelve astrological houses and shows which zodiac signs fall on each house cusp along with where your planets land. The houses represent areas of life, from the first house of self and identity to the tenth house of career and the seventh house of partnership, so knowing your house placements turns a list of planet-in-sign positions into a map of where life themes actually play out.

Calculating houses requires your exact birth date, time, and location, because the house framework is anchored to the Ascendant, the degree rising on the eastern horizon at your birth. From that anchor a house system divides the rest of the chart. Common systems include Placidus, Whole Sign, Koch, and Equal House, and they can disagree about which house a planet occupies, especially near a cusp, so it helps to know which system the tool uses.

Reading the houses, the first governs identity and appearance, the second money and values, the third communication and siblings, the fourth home and roots, the fifth creativity and romance, the sixth work and health, the seventh partnerships, the eighth shared resources and transformation, the ninth travel and philosophy, the tenth career and status, the eleventh community and hopes, and the twelfth the unconscious and solitude. A planet's house tells you the stage on which its energy expresses.

Combine this with the Midheaven Calculator, which defines your tenth-house cusp, and the Aspect Pattern Calculator to see how planets in different houses relate. Because house placement is so time-sensitive, a verified birth time from your birth certificate produces far more reliable results than an estimate.
