FAQ
Are Four Pillars and BaZi the same calculation?
In this calculator context, Four Pillars refers to the BaZi year, month, day, and hour pillars computed from birth date, time, and location basis.
Why does the hour pillar need exact time?
The hour pillar depends on the local birth hour. Without that hour, LifeSense does not invent a precise pillar.
Can true solar time affect the Four Pillars?
Yes, when exact time and location are available, true solar time can be part of the calculation basis and may affect hour-sensitive boundaries.
