Placidus Birth Chart Calculator

What Is the Placidus System?

The Placidus house system divides the sky into twelve unequal houses based on the rotation of Earth, your exact birth time, and location. Unlike the simpler “equal house” or “whole sign” systems, Placidus reflects the time it takes for each degree of the zodiac to rise over the horizon.

This means:

• Houses vary in size depending on latitude.
• Your chart feels more individualized and precise.
• It highlights time-based rhythms, making it a favorite for modern astrology and psychological insights.

Think of Placidus as a personalized lens on your destiny, showing not just where your planets are, but how they play out in specific life areas—career, relationships, spirituality, money, and more.

What Does a Placidus Birth Chart Reveal?

When you generate your chart using the calculator, you’ll see key details such as:

• Sun and Moon positions → Core identity and emotional needs.
• Ascendant (Rising sign) → Your outer personality and life approach.
• Midheaven (MC) → Career path and public reputation.
• Planetary placements → Mercury through Pluto, each with a unique role in your story.
• Placidus houses → 12 areas of life, from love to health to transformation.
• Chart summary → Dominant house, chart pattern, and quadrant emphasis for big-picture insights.

Together, these elements weave the fabric of your unique cosmic blueprint.
