Daymaster is an AI-powered Chinese metaphysics reading app. It computes two classical systems — Bazi (八字, the Four Pillars of Destiny) and Zi Wei Dou Shu (紫微斗数, Purple Star Astrology) — and reads them in synthesis to explain your nature, your timing, and the decade ahead.

What is true solar time and why does it matter for a Bazi chart?

True solar time is clock time corrected to the sun’s actual position at your birth longitude (with an Equation-of-Time adjustment), rather than the political timezone. Because the hour pillar — and therefore much of the chart — depends on the exact solar hour, using the political timezone is the most common source of error in other tools. Daymaster corrects for it automatically.

What is the difference between Bazi and Zi Wei Dou Shu?

Bazi (Four Pillars) reads the inner cause layer — your energy, personality, and potential, anchored by your Day Master. Zi Wei Dou Shu reads the outer effect layer — specific life events across twelve palaces. Daymaster synthesizes the two rather than presenting them as disconnected charts.

Do I need my exact birth time?

A precise birth time gives the most accurate chart because the hour pillar and several Zi Wei palaces depend on it. Daymaster still produces a meaningful reading with an approximate time, and corrects clock time to true solar time using your birthplace.

Built Differently

Three things most metaphysics tools get wrong — and how Daymaster gets them right.

✦

Every chart is computed from true solar time — clock time corrected to the sun’s real position at your birth longitude, with an Equation-of-Time adjustment. It’s the detail most other tools get wrong.
