Qi Men Dun Jia Quick Calculator
Enter your date and time to generate a simplified Qi Men Dun Jia reading (year/day/hour pillars, Yin/Yang Dun, Ju number, and focus palace).
Note: This is an educational, simplified calculator and not a full classical professional chart.
What is Qi Men Dun Jia?
Qi Men Dun Jia (奇門遁甲) is an ancient Chinese metaphysical system used for timing, strategy, planning, and decision support. In classical practice, a chart is constructed from exact time, calendar cycles, and directional palaces. Practitioners use the chart to evaluate momentum, opportunities, and hidden factors before taking action.
Historically, it was associated with military strategy, but today people commonly apply it to business decisions, negotiations, career moves, travel timing, and problem solving.
What this calculator gives you
This page provides a practical, lightweight Qi Men Dun Jia estimator for quick study. It calculates:
- Year pillar (Heavenly Stem + Earthly Branch)
- Day pillar (Stem + Branch)
- Hour pillar (Stem + Branch)
- Dun type (Yin Dun or Yang Dun)
- Ju number (1 to 9, simplified cycle)
- Focus palace (mapped from Ju and hour branch)
How to use this calculator
Step-by-step
- Choose the specific local date and time for your question.
- Click Calculate.
- Review pillar information for timing context.
- Use Dun type and Ju number for broad chart climate.
- Use focus palace as a directional/elemental cue for planning.
When to run a chart
Most people calculate at the moment of decision: before a call, pitch, launch, meeting, trip, or major commitment. Consistency matters. If you use the same method each time, you can build a meaningful decision journal and improve pattern recognition.
Interpretation basics
Yin Dun vs Yang Dun
In this simplified model, periods near winter are treated as Yang Dun and periods near summer as Yin Dun. Think of Yang Dun as outward growth and expansion; Yin Dun as consolidation, refinement, and internal strategy.
Ju number (1-9)
The Ju number marks the energetic phase in a nine-step rhythm. Lower and higher values are not inherently good or bad. The value is most useful when compared across multiple dates while planning timing options.
Focus palace
The calculated palace gives a quick emphasis for direction and element. For example:
- Kan (North, Water): research, adaptability, deep work
- Li (South, Fire): visibility, branding, communication
- Qian (Northwest, Metal): leadership, authority, mentors
- Xun (Southeast, Wood): growth, networking, long-term plans
Best practices for real-world decisions
- Use Qi Men as a decision aid, not a replacement for critical thinking.
- Compare two or three candidate times before committing.
- Track outcomes in a notebook to improve your interpretation skill.
- Combine chart signals with practical constraints like budget, team capacity, and deadlines.
Limitations of this simplified tool
Traditional Qi Men Dun Jia analysis can involve richer layers: full palace configuration, doors, stars, deities, hidden stems, exact solar terms, and advanced method variants. This calculator intentionally keeps things simple for accessibility and learning. For high-stakes decisions, consider a full professional charting method.
Quick FAQ
Is this suitable for beginners?
Yes. It is designed as a learning-friendly entry point to core timing concepts.
Why might results differ from another calculator?
Different schools use different rules for calendar boundaries, solar terms, and chart construction. This page uses a clearly simplified approach.
Can I use this for business timing?
Yes, especially for preliminary comparison across possible dates. Pair it with practical planning and risk review.
