EqualThe equal house system defines the Ascendant as the cusp of the first house. Each house has the same size ("equal") of exactly 30°. The 10th house cusp therefore does not coincide with the MC but is square to the Ascendant and consequently the highest point of the zodiac above the horizon. The equal house system has been in use since the time of antiquity. More information can be found in the Astro Wiki |
