Rosé's (BLACKPINK) BaZi — Pattern Fixed, Rest Splits
BLACKPINK member Rosé (Park Chae-young) has a publicly listed birth date of February 11, 1997, on Wikidata (Q27655344). Running this date through the KLifeMap engine gives — year pillar Ding-Chou (丁丑), month pillar Ren-Yin (壬寅), day pillar Jia-Shen (甲申).
No hour pillar — so we read three pillars only¹
The public record has no birth time. The hour pillar needs a time to build, so we leave it blank and judge only from the year, month, and day pillars. We do not fill the hour in with noon.
What doesn't move — the pattern is fixed at Hurting Officer
The day master (the heavenly stem of the birth day) is Jia (甲, Yang Wood), and the birth month is Yin (寅). Running all twelve possible hour branches through the engine (with the date held fixed), the pattern comes back Hurting Officer pattern (傷官格) in all twelve cases. This one thing can be stated with confidence even without knowing the birth time.
Compared to the other stars covered so far: for Jungkook and Karina, body strength and the useful element were fixed while only the pattern split. For IU, only the useful element was fixed. Rosé is the opposite — the pattern is fixed, while the useful element and body strength split together. Which values stay fixed and which split depends on the combination of birth season and day master, and can only be known by actually running all twelve cases each time.
What splits with time — the useful element and body strength
The useful element splits two ways depending on the hour branch: Water (水) in 8 cases, Fire (火) in 4 cases. Body strength splits along with it: weak (身弱) in 8 cases, strong (身強) in 4 cases (the Water and weak cases overlap). Even the most common outcome only holds in 8 of 12 cases — without a known birth time, it cannot be stated as a single certainty.
What we don't do
This piece does not make claims about personality or life direction. It only separates, as-is, what the KLifeMap engine determines for this date regardless of time (the year/month/day pillars, the pattern) from what changes with time (useful element, body strength).

¹ With no recorded hour, the eight-character chart is read as three pillars (year/month/day) only — the hour pillar is left blank rather than guessed.
