10 Eastern Types

Your Eastern Type comes from your Day Master — the Heavenly Stem of your Day Pillar. It is an entry point, not the whole story. The same Core Type can appear differently depending on the full chart.

How it works

The calculator identifies the Heavenly Stem of your Day Pillar, called your Day Master. That stem maps deterministically to one of these ten names; the rest of the chart adds context.

A careful boundary

Eastern Types are an interpretive framework for cultural exploration and self-reflection, not a scientific personality diagnosis, medical advice, or fixed prediction.

Direct answer

What is Eastern Types?

Eastern Type maps the calculated Day Master to one of ten chart-based Eastern Types. Each type is an interpretive framework for cultural exploration and self-reflection, not a scientific personality diagnosis, fixed identity, or prediction.

How it works

Enter birth date, place, and time when known. The deterministic engine calculates the chart; interpretation explains the displayed signals in plain English.

What you get

You can review Four Pillars, Day Master, Five Element presence, and an Eastern Type starting point. The Deep Personal Profile is coming soon, not available now.

Limitations

This is a cultural self-reflection framework, not a scientific test or a fixed prediction. It does not provide medical, legal, financial, or other professional advice. If birth time is unknown, the Hour Pillar is not invented; the result is explicitly partial.

Frequently asked questions

How are Eastern Types assigned?

They are assigned from the Day Master stem and its element and polarity.

Is one type the whole chart?

No. The full Four Pillars and element context can change how a type is expressed.

Are Eastern Types scientifically validated?

No scientific validation is claimed; they are presented for cultural exploration and reflection.
