What you get
- Four Pillars with hidden stems and Ten Gods
- Day Master and Five Elements balance
- Da Yun start time, current cycle and full timeline
How it works
- Inputs
- Birth date, time, gender and birth city; the form uses the matching timezone and longitude.
- Method
- Correct local solar time from the birthplace, historical timezone and longitude, calculate the Four Pillars, then organize the reading around the stated topic.
How to read it
Confirm the calendar, birthplace, timezone and true solar time first. Then read the Day Master and element structure before moving to the current Da Yun and life themes.
Need to verify the calendar, solar term or corrected time before a birth chart? Start with the Chinese lunar calendar and solar-time converter.
Want to compare a birth-time chart using twelve palaces and its own convention notices? Open the Zi Wei Dou Shu twelve-palace calculator.
Set the calendar, place and solar-time reference first
Start by choosing the calendar you actually have, then enter the birth date, clock time, gender category and birthplace. For a result you can compare later, keep the time zone with the place. The chart uses the solar-term frame for the year and month, so a date close to a solar-term boundary should be checked with its local time zone rather than read from a date-only shortcut.
Use the precise input path when the birthplace longitude matters. The result keeps the civil clock time, the corrected local solar-time reference and the total correction together. If the correction moves the time across a double-hour boundary, preserve both nearby possibilities and compare their four pillars instead of choosing a precise time that was never recorded.
Worked example: four pillars after solar-time correction
This is a site-authored worked example with a fixed input: 20 February 1984 at 10:30, male, Beijing, Asia/Shanghai, longitude 116.4000°. The calculator records a solar-time reference of 10:01 after a total correction of −28.45 minutes, then returns the four pillars shown below. Keeping the input fixed lets another reader reproduce the same structural result.
Read from the four pillars to the Day Master, hidden stems and the Da Yun timeline, keeping each layer separate. These are chart structures and time layers, not predictions of a job, relationship, health or financial event. If your own corrected time is near a boundary, rerun the neighboring time and use real biography and present conditions to check which input is credible.
- Fixed input
- 20 February 1984 · 10:30 · male · Beijing · Asia/Shanghai · longitude 116.4000°.
- Solar-time reference
- 20 February 1984 10:01 · total correction −28.45 minutes.
- Four Pillars
- Jia-Zi (甲子) · Bing-Yin (丙寅) · Jia-Shen (甲申) · Ji-Si (己巳).
- Day Master
- Jia Wood (甲木).
- Boundary handling
- The corrected time remains in the same displayed double-hour here; compare adjacent times when a real birth is close to a boundary.
