What are the
27 Mansions?
In ancient Chinese astronomy, the moon travels through 27 distinct star regions — called Lunar Mansions — over the course of a month. The mansion the moon occupied at your birth becomes your permanent celestial code.
Unlike Western astrology's 12 signs, MansionOS uses 27 precisely calculated positions, each with a distinct personality architecture, relationship pattern, and karmic signature.
This is not your personality. This is the operating system beneath it.
About MansionOS
MansionOS turns your birth date into a personalized reading based on the 27 lunar mansions and the Chinese zodiac — your star profile, your daily energy, and the bonds between you and the people in your life.
For entertainment and self-reflection only. MansionOS is not professional advice of any kind — medical, psychological, legal, financial, or relationship. Always consult a qualified professional for matters affecting your health, finances, or wellbeing. You must be 18 or older to purchase.

How MansionOS works
MansionOS reads the sky you were born under — and the one moving overhead today. Ancient Eastern astronomy tracked the moon through 27 lunar mansions; the one it stood in the day you were born becomes your fixed star-code. From there: your profile, your daily energy, and the bonds between you and the people in your life. For reflection, not prediction.
Your Identity · Star Mansion & Zodiac
Your birth mansion (1 of 27) and Chinese zodiac: the operating system beneath your personality — how you're built, your blind spots, the year ahead.
How it's made — calculated from your exact birth date through the lunar almanac: the real mansion the moon occupied that day, not a 12-sign generalization.
Today's Energy
How today's sky meets yours: an energy score, your peak window, and what to lean into vs. what to leave alone.
How it's made — your birth mansion measured against today's real lunar mansion (值日宿): yours for today, not a generic horoscope.
Your 27-Day Cycle
The moon walks all 27 mansions, one a day, and comes home to yours every 27 days. See which phase you're in — Active (push) · Waning (protect) · Turning (plan) — and what it's good for.
How it's made — counted from where today's moon sits relative to your birth mansion; the cycle resets on the day they align (命).
Relationship Readings
Enter someone's birth date to see the bond between you: your archetype, the friction pattern, and how to navigate it. Tell us who they are to you, and the reading speaks in that register — family, friend, partner, or work.
How it's made — the distance between your two birth mansions sets the bond; today's moon, measured against both of you, sets whether today runs aligned, friction, or clash.
