About

In Chinese Metaphysics, BaZi (Eight Characters) is a sophisticated system of destiny analysis. While most basic tools calculate the Four Pillars (Year, Month, Day, Hour), advanced practitioners know that the 12 Palaces (Ming Gong) provide the critical context—the "where" and "how" of destiny. These palaces describe specific life domains such as Marriage, Wealth, Career, and Parents.

Accuracy in BaZi is entirely dependent on time. A standard clock time is often inaccurate for astrological purposes because 12:00 PM on a clock is rarely "True Noon" (when the sun is highest). This tool includes a Solar Time Correction algorithm. By inputting your longitude, it adjusts the birth time to the precise solar minute, ensuring your 12 Palaces chart is calculated based on astronomical reality rather than political time zones.

Formulas

The calculation of the Life Palace (Ming Gong) depends on the Solar Month and Solar Hour of birth. The Equation of Time (EoT) is used to correct the clock time.

Time_solar = Time_local + (Long_user − Long_timezone) × 4 min

The Ming Gong branch is determined by:

Branch_ming = 14 − (Month_branch + Hour_branch)

Frequently Asked Questions

Most simple calculators use 'Clock Time'. We use 'True Solar Time'. For example, if you were born in western China but use Beijing time (one timezone), your solar time could be nearly 2 hours earlier. This shifts your Hour Pillar and completely changes your 12 Palaces.

The Life Palace represents your inner self, your true potential, and the lens through which you view the world. While the Day Master (in the main chart) is 'You', the Life Palace is your 'Home Base' or psychological background.

You can search 'Longitude of [City]' on Google. The calculator requires decimal format (e.g., 120.5) rather than degrees and minutes.

Yes. If you were born during DST, you should subtract 1 hour from your birth time before entering it, or rely on our solar correction if you input the correct GMT offset for that specific date.
