How the House System Astrology Calculator Works

Astrological houses divide the sky into 12 segments, each representing different aspects of life. The calculator uses your birth information to determine the exact degree positions of the houses.

Step 1: Enter Birth Data

• Date of birth
• Exact time of birth
• Place of birth (city and country)

Step 2: Select House System

Common systems include:

• Placidus
• Koch
• Equal House
• Whole Sign
• Porphyry

Step 3: Calculate House Positions

The calculator computes the ascendant (rising sign) and distributes the remaining houses according to the chosen system.

Step 4: View Planetary Positions in Houses

The tool can overlay planetary positions, revealing which planets occupy which houses, giving insights into personality, career, relationships, and more.

Plain Text Formulas

1. Ascendant Calculation (Rising Sign):

Ascendant = Arctangent((cos(Latitude) × sin(Local Sidereal Time)) ÷ cos(Local Sidereal Time))  

2. House Cusps (Placidus Example):

House Cusp = Ascendant + (House Division Factor × 30°)  

3. Planet in House:

Planet House = Find house where Planet Longitude > House Start Longitude AND < House End Longitude 

These formulas are simplified representations; actual astrology calculations involve spherical trigonometry and ephemeris data.
