FAQ
Frequently asked questions
What is Daymaster?
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 a Day Master?
The Day Master (日主) is the heavenly stem of your birth-day pillar — the anchor element of your whole Bazi chart. Everything in a Bazi reading is interpreted in relation to it: which elements support you, which drain you, and how your timing flows.
Is Daymaster accurate?
Charts are computed by a versioned, master-calibrated engine and use true solar time (corrected from your birth longitude, with an Equation-of-Time adjustment) — the detail most other tools get wrong. Accuracy of the chart depends most on the precision of your birth time and place.
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. If you do not know your birth hour at all, Daymaster has a free birth-time rectification tool: give it three to five dated life events and it tests all twelve two-hour branches against your history and ranks the best fit.
What is the difference between Bazi and Zi Wei Dou Shu?
Bazi (Four Pillars) reads the inner-cause layer — 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 showing two disconnected charts.
How is this different from Western astrology?
Western astrology is built on the positions of planets along the zodiac. Bazi and Zi Wei Dou Shu are built on the Chinese solar/lunar calendar, the Five Elements, and the heavenly stems and earthly branches — a different system with its own logic of timing, compatibility, and life events.
Does Daymaster do Western astrology as well as Chinese astrology?
Yes. Daymaster computes a full Western tropical natal chart — Sun, Moon, rising sign, the planets, whole-sign houses and Ptolemaic aspects — from ephemeris data, plus a daily transit-based horoscope; the rising sign and the houses need a known birth time. It is presented alongside the Bazi chart rather than merged into it: the two systems share no data and no method, so where they agree you have corroboration and where they differ you have a question worth asking. The Western birth chart is free.
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 can I use Daymaster for besides a full reading?
Your chart is the coordinate system for a set of tools that each ask a different question against it: a Western birth chart with daily transits, compatibility between two charts, tarot read through your day master and current luck pillar, a Qi Men Dun Jia board for the hour you ask in, a daily guidance card, auspicious date selection for weddings or launches scored against your own day pillar, Chinese name analysis (五格 five-grid plus the eighty-one number table), and birth-time rectification. Several have a free layer; some need a free account.
Is my birth data private?
Your account and your charts are private to you. Readings are stored with your account so you can come back to them; they are not shared publicly unless you explicitly create a share link.
How are the readings generated?
The chart itself (pillars, palaces, fortune curve, event scoring) is computed deterministically by Daymaster’s own engine. The written narrative is then composed by Daymaster’s narrative engine, grounded strictly in that computed chart — so the prose explains your actual chart rather than generic descriptions.
Can I install Daymaster as an app on my phone?
Yes. Daymaster is a web app you can add to your home screen — no app store needed. On iPhone (Safari): tap the Share button, then “Add to Home Screen”. On Android (Chrome): tap the menu, then “Install app”. On desktop (Chrome/Edge): click the install icon in the address bar. It then opens full-screen like a native app and can send notifications.
