Jackson Wang's (GOT7) BaZi — All Three Values Stay Fixed
GOT7 member Jackson Wang has a public birth date of March 28, 1994, per Wikidata (Q16905948). Running this date through the KLifeMap engine gives — Year Pillar Jiǎ-Xū (甲戌), Month Pillar Dīng-Mǎo (丁卯), Day Pillar Guǐ-Chǒu (癸丑).
No hour pillar — so we read three pillars, not four
None of the public records give a birth time. The Hour Pillar needs a time to be set, and without it we leave that pillar blank and judge only from the Year, Month, and Day pillars. We don't fill the blank with noon or guess at a time.
This time, all three stay fixed — Pattern, Useful God, and Strength
His Day Master (the stem of his birth day) is Gui (癸), and he was born in the month of Mao (卯). Running all twelve possible hour branches (Zi through Hai) while holding the date fixed, all twelve cases come out identical: Pattern is Hurting Officer (傷官格), Useful God is Metal (金), and the chart reads as weak (身弱). Birth time moves none of these three.
Compared with the stars covered so far — Jungkook and Karina had Strength and Useful God fixed while only the Pattern split; IU had only the Useful God fixed; Rosé had the Pattern fixed while Useful God and Strength split. Jackson is the first of the five where all three stay fixed. Which values stay fixed and which split depends on the specific combination of birth season and Day Master — it has to be measured by actually running all twelve cases each time.
What only a birth time can settle
The Hour Pillar itself (its stem and branch) and the palace it points to (traditionally read for things like one's relationship with children) cannot be determined either way without a birth time. This piece stays blank rather than guessed at.
What we don't do
This is not a personality or life-direction verdict. It simply lays out, as-is, what the KLifeMap engine determines for this date independent of birth time (Year/Month/Day pillars, Pattern, Useful God, Strength).
You can run your own birth date through KLifeMap's BaZi engine and get the full reading — the same input always produces the same result.
