Which K-pop idols share my day master?

Every idol below has a page on Bias Match, with a birth date taken from public sources. That covers 183 idols from BABYMONSTER, IVE, RIIZE, TREASURE, NMIXX, Stray Kids, KISS OF LIFE, TXT, ITZY, TWICE, NCT DREAM, KATSEYE, SEVENTEEN, TWS, NCT 127, &TEAM, aespa, NewJeans, LE SSERAFIM, ATEEZ, P1Harmony, ILLIT, STAYC, BTS, BOYNEXTDOOR, ENHYPEN, BLACKPINK, ZEROBASEONE, i-dle so far, and the list grows as more groups are checked. The day master is the heavenly stem of the birth day, the one character in a saju chart that stands for the person. If that term is new, start with what your day master says about you.

Birth hours aren't public, so each chart here is read from the birth date alone. That is enough for the day master, with one catch: someone born late at night could belong to the next day's stem. Treat each entry as the calendar-day reading.

This page is a fan-made list for fun. It says which stem each idol's birth date falls on, nothing more. It doesn't describe who any of them are.
