I don’t know my birth time

Time basisClocks follow your time zone’s standard meridian, so the Sun at your birthplace can run minutes ahead of or behind the clock. Longitude correction fixes that offset; true solar time also adds the seasonal equation of time (±16 min). Rat-hour rule (23:00–00:59)Only matters if you were born between 23:00 and 23:59. Most modern practitioners use the early Rat-hour rule.

Why does birth time need correcting? ▾

Solar time, not clock time. In BaZi the hour pillar, and the day pillar near midnight, follow where the Sun actually was. Clock time is set for a whole time zone, so at your birthplace the Sun may cross the meridian earlier or later than clock noon. We use the longitude of your birthplace to correct for that, and can also add the equation of time (from −14 min in February to +16 min in November).

Daylight saving time is taken from your browser’s time zone database for the birth date, so summer-time births are converted to standard time automatically.

Whichever basis you pick, the “Pillars under each time basis” panel shows every combination side by side. If they differ, choose the one closest to the time on your birth certificate.

About Your Destined Spouse

In BaZi, the branch of your day pillar is called the spouse palace (配偶宮). Its element, its Ten God and its life stage are traditionally read as a portrait of your partner and of married life.

How it is calculated

Fate Hall reads the spouse palace together with the spouse stars in your chart, then looks at the Luck Pillars and yearly pillars that combine with or bring those stars, which classical texts associate with timing of marriage.

Reading it well

A portrait like this is a starting point for conversation, not a requirement. Many couples enjoy comparing what their charts say about each other — the Compatibility page shows both charts together.

The spouse palace in brief

The twelve branches each carry a main element and hidden stems. A spouse palace in a Water branch, for example, is traditionally read as a thoughtful, adaptable partner, and one in a Fire branch as warm and expressive. Combinations between your spouse palace and the yearly pillars mark years traditionally linked with meeting or committing; clashes mark years of change in a relationship. See The Twelve Earthly Branches for each branch’s character.
