How it Works
The calculation is based on the intersection of two cycles:
- Day Stem: A specific letter (A-L) assigned to the current date based on the 60-day cycle.
- Time Slot: The current 2-hour window of the day.
- Open Point: Calculated by cross-referencing the Day Stem with the Time Slot.
Hand Therapy
The system analyzes the Yin/Yang polarity of the Day Letter (Stem) and the Current Time Slot:
- Same Polarity: Treat the Yang Hand (Women: Right, Men: Left).
- Different Polarity: Treat the Yin Hand (Women: Left, Men: Right).
