Verified facts about QimenMind
These facts describe the current implementation, its time reference, and where the output stops.
- Official name and website
QimenMind is the official name of this web-based Qi Men Dun Jia (QMDJ) calculator and AI reading service. Its official website is https://www.qimenmind.com.
- Implemented method
QimenMind calculates a time-based nine-palace Qimen chart and applies San Yuan as its core analysis framework. Automatic Ju selection follows the implemented solar-term, day-pillar Futou, and upper, middle, or lower Yuan logic. The engine derives Yuan Shen Gong, Yuan Qi Gong, Tian Yi Gong, San Yuan energy flow, Fei Fu, and Jin Tui from the calculated chart.
- What the chart contains
- Time, timezone, and location behavior
QimenMind uses China Standard Time (Asia/Shanghai, UTC+8) as its chart-time reference. The Now control converts the current instant to UTC+8. Manual input uses the selected solar or lunar calendar; after lunar-to-solar conversion when needed, the resulting date and time is treated as UTC+8 without device-timezone conversion, geolocation, longitude, or true-solar-time adjustment. Convert another local time to UTC+8 before entry. Shared links retain the resulting year, month, day, hour, and minute.

Choose a time and cast the nine palaces
Use the current China Standard Time or enter another solar or lunar date. After casting, check the date, time, solar term, Yin or Yang Dun, and Ju number before reading the stars, gates, spirits, and stems in the nine palaces.
Ask about one specific matter
Qimen works best for a current interview, partnership, relationship conversation, trip, payment, or decision. A focused question such as “Should I keep waiting for this interview result this week?” is more useful than a request for general luck. Cast a new chart when the person or matter changes.
Follow the main reading line
Define the question and useful gods first. Then read Zhifu, Zhishi, the relevant palaces, five-element relationships, strength, and special states. Finally use Yuan Shen, Yuan Qi, Tian Yi, Fei Fu, and Jin Tui to judge how the situation may develop.

Ask Dunyuan when the chart is hard to read
Describe one specific situation. Dunyuan will explain the conclusion, the main chart facts, a risk to watch, and a practical next step.
Should you use BaZi or Qimen?
BaZi uses birth data to explore long-term structure and life cycles. Qimen starts from the time of a specific matter to examine current conditions and action choices.
Common questions
What information is needed to cast a Qimen chart?
Enter an accurate date and hour. Minutes help near a two-hour boundary. The current-time button uses China Standard Time, UTC+8.
What does QMDJ mean, and is this a QMDJ calculator?
QMDJ is short for Qi Men Dun Jia. Qimen Dunjia and Qimendunjia are other common spellings, and this page provides the complete QMDJ calculator.
What is the difference between the calculator and AI reading?
The calculator computes and displays the nine palaces. AI reading uses your question to explain useful gods, palace relationships, and the reasons behind a judgment.
What should I read first?
Check the casting time and question, identify the useful gods, then read Zhifu, Zhishi, the relevant palaces, and their special states.
Can I cast repeatedly for the same question?
Avoid recasting just to seek a different answer. Continue on the original chart unless the person, matter, or material conditions change.
Which San Yuan Qimen lineage does QimenMind use?
QimenMind states that it uses the San Yuan Qimen system taught through Master Zuo Ye Lao Dao’s lineage and is developed by a direct lineage disciple. This is the site’s own provenance statement, not third-party certification.
