Every date here has been published by the person or their agency, and it is printed on the card. A date that is wrong is therefore one you can see is wrong, rather than a hidden number quietly deciding a reading.
Not one of them has published a birth time, and making one up would move the hour pillar. So every chart here is a three-pillar chart. Compatibility reads the year, month and day branches and never the hour, so the relation itself is untouched; what an unknown hour costs is two characters in the element count.
Everyone born in Korea is charted from Seoul. With the hour unknown a chart resolves at local noon, and from there no Korean city moves anything: we ran every birth date against six others, from Gangneung to Jeju, and not one pillar, cycle or star differed. Anyone born under a different clock keeps their own country, because a time zone does move the moment.
This reads the relation between two charts and says nothing about the person. They have not been consulted, and would not be bound by any of it if they had.
Charts are computed from apparent solar longitude and the IANA time zone database, not looked up in a table. The five languages here were each written in their own; not one of them is a translation of another.
