True solar time adjusts clock time to actual solar position at your birth location, critical for accurate Saju hour pillar calculation.
Clock time differs from true solar time due to time zones, daylight saving, and the equation of time (Earth's elliptical orbit). For Saju, which uses two-hour periods, even small time differences can change the hour pillar. True solar time calculation uses birth longitude to determine when the sun was actually at its positions, ensuring accurate pillar assignment.
TriAstra automatically converts all birth times to true solar time for Saju calculations, using the Swiss Ephemeris for precise solar position.
If you know your exact clock time of birth, TriAstra handles the conversion. True solar time ensures your hour pillar is correctly calculated.
