BaZi time basis 时间方式

Your time zone identifies the recorded birth instant; true solar time adjusts the calculation clock for your birthplace and the Sun’s seasonal timing, which may change your chart near an hour or date boundary.

How birth time affects your chart

Birthplace longitude

Shared with Zi Wei. Changing the time basis or longitude updates both charts; your recorded birth time stays unchanged.
