Ancient Eighteen Flying Stars
What Birth Details Are Needed for a Zi Wei Dou Shu Chart?
Prepare the birth date, recorded local time, birthplace, and method-specific gender input needed to build an Ancient Eighteen Flying Stars chart.
Direct answer
To build a Zi Wei Dou Shu chart, prepare the recorded birth date in the local Gregorian calendar, the local time with minutes if available, the birthplace city or nearest reliable city, and the gender marker used by this method's cycle-direction rule. Enter the record as written; do not convert an overseas birth to Beijing time. The system handles birthplace-based correction before assigning the traditional two-hour gate.
How to read it
Use the Gregorian date and local civil time written on the birth record. Keep the recorded minutes even though the final chart uses a traditional two-hour shichen: longitude, historical time-zone rules, daylight saving, and the equation of time can move a time near a gate boundary. Do not round first and do not manually convert an overseas birth to China time.
Enter the birthplace as city, region, and country. It supplies the time-zone and longitude context used for true-solar-time correction. If the exact town is not available in the location selector, choose the nearest city with the same practical time basis and keep a note that it is an approximation.
The form also asks for a male or female marker because the documented Ancient Eighteen Flying Stars method combines that input with the birth-year stem polarity to set Daxian direction. It is a calculation field only; it does not assign personality, family duty, social role, or relationship behaviour.
If the hour is uncertain, enter the narrowest honest range rather than guessing. A range contained within one two-hour gate can use its midpoint as a working input, with uncertainty disclosed. A wider range or a boundary case should be compared across candidate gates or taken to the separate birth-time reconstruction flow.

Prepare these birth details
1. Local Gregorian birth date
Use the calendar date recorded at the birthplace, not a manually converted China date or a self-calculated lunar date.
2. Recorded local clock time
Keep the hour and minutes from the record. Mark the source and whether the time is exact, approximate, or unknown.
3. Birthplace
Provide city, region, and country. If the city is unavailable, choose a nearby city with a comparable time basis and disclose the approximation.
4. Gender calculation field
This method uses the selected marker with the year-stem polarity only to determine Daxian direction.
5. Record confidence
Distinguish an official record, family memory, estimated range, and unknown time so the result does not imply more certainty than the input.
Example
If a Toronto birth record says 14:32, enter the recorded Toronto date, 14:32, Toronto, Ontario, Canada, and the required calculation marker. Do not convert 14:32 to Beijing time. Destin Field checks the location-based time context, displays the corrected time, and then assigns the corresponding two-hour gate.
Common misunderstandings
- The minute is not a separate sixty-part chart, but it still matters when correction approaches a two-hour boundary.
- Birthplace is a calculation input for time handling, not decorative biography.
- An unknown birth hour should be marked and compared, not replaced with noon or a favourable-looking gate.
Reading boundary
The chart is only as specific as the birth record supplied. Keep uncertainty visible; this cultural reading does not verify a missing time or guarantee an event or outcome.
Questions people ask
Do I need my exact birth minute?
Use it if recorded. The final method uses a two-hour gate, but minutes matter when birthplace-based correction is close to a boundary.
Do I enter local birth time or Beijing time?
Enter the local civil time recorded at the birthplace. Do not manually convert an overseas record to Beijing time.
What if my town is not listed?
Choose a nearby city that shares the practical time-zone context, keep the location as close as possible, and treat the result as using an approximate location.
What if I do not know the birth time?
Mark it as uncertain. Use a narrow documented range when available, compare adjacent gates near a boundary, or open birth-time reconstruction for a wider range.
Do I need an account to create the free chart?
No. The form draft stays in the browser, and the encrypted chart session used to open the result expires within two hours.
