Astrology has fascinated humanity for millennia, offering insights into personality, destiny, and life’s cycles through celestial patterns. Among the essential tools in astrology is the house chart—a unique map dividing the sky into twelve sections (houses) at the exact moment and place of your birth. Each house governs different aspects of your life, from personal identity to career and relationships.

Our House Chart Calculator is designed to help you effortlessly generate your complete astrological house chart. By entering your birth date, time, and geographic coordinates, you can reveal the exact positions of all twelve houses, including critical points like the Ascendant (1st House), Descendant (7th House), and Midheaven (10th House).

Whether you’re a beginner exploring astrology or an enthusiast seeking quick, accurate calculations, this tool provides clear, personalized results.

What is a House Chart?

A house chart divides the sky into twelve segments starting from the eastern horizon at your birth time, showing which zodiac sign governs each “house.” Unlike your sun sign, which is based only on your birth date, the house chart depends on the exact time and place of birth, revealing deeper layers of your personality and life path.

1st House (Ascendant): Your self-image and outward personality.
2nd House: Personal finances, possessions, and values.
3rd House: Communication, siblings, and short trips.
4th House (IC): Home, family roots, and inner emotional foundation.
5th House: Creativity, romance, and children.
6th House: Health, daily routines, and work environment.
7th House (Descendant): Partnerships and marriage.
8th House: Transformation, shared resources, and secrets.
9th House: Higher learning, travel, and philosophy.
10th House (Midheaven): Career, public image, and goals.
11th House: Friendships, groups, and aspirations.
12th House: Subconscious, privacy, and spirituality.
