What ist the Equal (MC) house system?
Last Updated: May 15, 2025
The Equal (MC) house system is a variation of the traditional Equal House system. In this system, each house is exactly 30 degrees, maintaining equal size, but the Midheaven (MC) is used to determine the position of the 10th house cusp rather than relying solely on the Ascendant.
Key features of the Equal (MC) system include:
- Equal House Sizes: Like the standard Equal House system, all houses are exactly 30 degrees in size. This creates a simple, uniform structure where each house spans an equal portion of the zodiac.
- Midheaven Placement: The major difference is that the 10th house cusp is aligned with the Midheaven (MC), which represents career, public life, and ambition. In other Equal House systems, the MC might not always fall exactly on the 10th house cusp.
- Consistency and Flexibility: The Equal (MC) system maintains the simplicity of equal house sizes while ensuring that the MC (a significant point in astrology) is accurately placed in the 10th house. This system is often used to ensure consistency in house sizes while incorporating a key point for career and public identity.
Astrologers who prefer this system appreciate its balance between simplicity (equal houses) and the meaningful placement of the MC. It combines the straightforward approach of Equal Houses with the flexibility of ensuring that the MC always aligns with the 10th house.
