Notes on Local Bazi Calculation:

  • True Solar Time: Calculations are based on exact GPS position, not national time zones.
  • Year Can Chi: Based on the Beginning of Spring (Li Chun) at the local time.
  • Month Can Chi: According to local solar terms and actual five elements.
  • Day Can Chi: Converted from local True Solar Time.
  • Hour Can Chi: Based on local solar time, divided into 12 actual double-hours.

Why use Local Solar Time for Bazi?

Traditional Bazi uses national time zones, but real solar time depends on local longitude. Differences can be up to 1-2 hours, causing shifts in the Day and Hour Can Chi.

True Solar Time

True Solar Time is the time calculated based on the precise position of the Sun in the sky at specific GPS coordinates, independent of administrative time zones.

Deviations can reach 15-30 minutes compared to administrative time, which is critical for accurate Bazi calculation.
