Did you know there are five different Astrology Human Design Chart calculation methods you can use on Genetic Matrix?  Did you also know you can use these new Astrology Human Design chart calculation methods with the Gene Keys chart?  You can also use the different chart calculations with the Health Manifested Human Design chart, Astro Gene Keys chart, and HD Astro chart.  You can use it with any chart on Genetic Matrix.  There are so many charts to choose from.

The five different Astrology Human Design chart calculation methods are Tropical, Sidereal, 13 Sign Sidereal, True Sidereal Kanatas, and True Sidereal Chimenti.  You can also go to the “Other Charts” section and choose the chart design you prefer.  There is the Genetic Matrix chart, the Health Manifested (HM) Quantum, Health Manifested (HM) Quantum + Astro, which I call the HD Astro chart, the HM Gene Keys chart, which I like to call the Astro Gene Keys chart.  You can also find the more traditional Gene Keys chart under Foundation charts and Gene Keys.

You can easily change the chart calculations in the first pull-down menu under the chart name.

The astrologer Athen Chimenti uses a custom Ayanamsa that uses the fixed start Beta Aries (Sharantan).  It is set to occupy 2 Aries 15 in the True Sidereal zodiac.  Chimenti’s system seems to be more consistent with the traditional constellation boundaries.  These are the zodiac dates based on the Chimenti system.  He also accounts for the overlap between the constellations.  He believes this is a more accurate system.  Chimenti also recommends when a planet is within 3 degrees of 2 signs it is best to look at the description of both zodiac meanings.
