Wu · Earth Day Master
Wu earth is the mountain: stable, reliable, slow to promise and hard to move once committed. People bring their storms to you because you do not sway. Your stillness is strength — just be careful not to turn patience into a wall.
Ten Day Masters — ten ways of being in the world
The Day Master is the stem of your day pillar, and the center of the chart. Find yours below; every other character is read in relation to it. These natural images are a teaching aid, not a verdict about your personality.
Like a towering tree: a straight trunk holding out branches that spread outward.
Like a vine or slender branch, bending with circumstances and growing on the support around it.
Like the sun overhead, casting light far and wide, bright and warm.
Like a nearby lamp: its light gathers close and needs oil and shelter to keep the flame.
Like a thick city wall, solid and grounded, marking the boundary between inside and outside.
Like soil in a field, holding seeds and moisture so plants can take root.
Like an axe or hammer: hard and heavy, its purpose is to be forged into shape.
Like a fine blade, valued for sharpness and the details of craftsmanship.
Like rivers joining, abundant water flowing over a wide range.
Like steady drizzle, falling on plants and soaking drop by drop into the soil.
Learn
Read your chart, step by step
You do not need to learn it all at once. Start with the question you have right now; each reading will take you a step further.
What are the four pillars?
Your year, month, day and hour, each written as a heavenly stem and an earthly branch — eight characters in all. Together they describe how you tend to meet the world, and what the years may ask of you.
Jump to this part →The Day Master is the center
The stem of your day pillar is the Day Master. Every other character in the chart is read in relation to it — which is why the same element can mean different things in different charts.
Jump to this part →Elements and Ten Gods
Element counts show composition, not strength. The Ten Gods show how each element relates to you — as resource, expression, wealth, responsibility, or companion.

Calendar and solar terms
Input uses the Gregorian calendar and supports 1900–2099. The year pillar changes at the Beginning of Spring and the month pillar at the twelve Jie. The birth instant is converted to the same absolute moment and compared with the term boundary, so births abroad do not fall into the wrong month or year because of time-zone differences. The day and hour pillars follow the local solar clock at the birthplace. With “Southern Hemisphere birth” selected, the month branch switches to its opposite branch and the month stem is recalculated from the year stem using the Five Tigers method.
Birth time
The birthplace timezone is resolved from an IANA timezone name, and the timezone database supplies the real offset at that historical moment, automatically handling daylight saving time and past standard-time changes (for example China’s 1986–1991 daylight saving period). True solar time = local standard time + longitude offset (relative to the standard meridian of the timezone, about 4 minutes per degree) + equation of time (about ±16 minutes through the year). When no longitude is entered, the chart uses the local civil clock time.
Zi hour and luck start
From 23:00 the day pillar rolls to the next day, and the hour pillar uses the next day’s stem as well. Major luck runs forward for yang-year males and yin-year females, and backward for yin-year males and yang-year females; the start age converts the interval from birth to the relevant solar term into a ten-year scale by the proportion of the solar-term month.
Boundaries of the result
The chart provides classical calendar fields and does not automatically judge chart patterns, useful or unfavorable gods, or fate conclusions. Different schools may use different rules for luck start and the Zi hour; if the birth time is near a solar term or hour boundary, verify the original record.
