Why is accurate solar terms calculation important?

"Years pass by, solar terms rotate - The foundation of East Asian calendar"

Astronomical Principle

Solar Orbit

The 24 solar terms are determined based on Earth's position on its orbit around the Sun (Ecliptic). The entire 360° circle is divided into 24 equal segments of 15° each.

  • Solar system: Solar terms are actually a solar calendar, fixed to the sun's position.
  • Reference point: Starts from Lichun (315°) or Vernal Equinox (0°).
  • Cycle: Each solar term lasts about 15 days.
Practical Significance

Natural Rhythm

The names of the solar terms reflect the actual changes in climate, weather, and phenology throughout the year, guiding agricultural cultivation and daily life.

  • Subtle observation: Detailed divisions of phases: rain (Yushui), insects awakening (Jingzhe), dew (Bailu)...
  • Metaphysics: Solar terms are the foundation for determining the Can Chi calendar in Eastern metaphysics.
  • Health cultivation: Guidelines for a lifestyle in harmony with the rhythm of nature.
Digital Technology

Precise Calculation

Combines a modern astronomical algorithm (Astronomy Engine) with digital geographic data to provide absolute accuracy.

  • Solar Time (Apparent Solar Time): Calculated based on actual longitude, not just administrative time zones.
  • Multi-platform: Standardized data for any location globally.
  • AI Integration: Analysis and forecasting based on historical and astronomical data.
