Four Pillars calculator
Four Pillars Calculator: understand your Ba Zi chart
Mira calculates a Ba Zi chart from birth date, birth time and birthplace, then turns the Four Pillars into a clear symbolic reading. The goal is insight, not fatalistic prediction.
What the Four Pillars show
A Ba Zi chart contains four pillars: year, month, day and hour. Each pillar combines a Heavenly Stem and an Earthly Branch, linked to the Five Elements and Yin/Yang polarity.
The Day Master is the center of the reading. Other elements are interpreted through their relationship to it: support, expression, resources, pressure, structure and value creation.
Why birthplace matters
Birthplace helps place the birth time in context. Time zone and solar correction can matter, especially when the corrected time approaches the boundary between Chinese hour pillars.
Mira keeps these limits visible and treats the reading as symbolic guidance, not an absolute statement about the future.
