Why is accurate solar terms calculation important?

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.
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.
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.
Frequently Asked Questions
Do solar terms change every year?
The start date of each solar term can shift by 1-2 days depending on the leap year, but the Earth's position in its orbit (solar longitude) is fixed.
Why is geographic calculation necessary?
Common calendars often use the average time of a time zone (e.g., GMT+7). However, the True Solar Time at each location differs depending on longitude. This difference can be up to 30-40 minutes, affecting the accuracy of the solar term transition time.
