Wan Nian Li (万年历) literally means "Ten Thousand Years Calendar." It is a perpetual Chinese calendar that maps each day to its corresponding Heavenly Stem (Tian Gan) and Earthly Branch (Di Zhi) combination, known as GanZhi. This calendar is the foundation for BaZi (Four Pillars of Destiny) calculations and traditional Chinese date selection.

The 24 Solar Terms (Jie Qi) divide the solar year into 24 segments based on the sun's position along the ecliptic. In BaZi analysis, the Jie (节) terms — which occur at the start of each solar month — determine when the monthly pillar changes. This is why precise Solar Term timing is critical for accurate BaZi chart calculation.

The Nine Flying Stars (Jiu Gong Fei Xing) are a system used in Feng Shui to track the movement of nine star energies through a 3×3 magic square (Lo Shu). Each day, the stars shift position, influencing the energy of different directions and spaces. Practitioners use the daily Flying Star number to assess auspicious and inauspicious influences.
