Your Day Master is the Heavenly Stem of your birth day pillar among 10 elemental stems (Gap/Eul Wood, Byeong/Jeong Fire, Mu/Gi Earth, Gyeong/Sin Metal, Im/Gye Water). Enter your birth year, month, and day in Heartloop's Saju calculator to compute your Day Master and Five Elements balance in 3 seconds.

2027 is the Year of the Red Fire Goat (Ding-Mi). Heartloop calculates how 2027's Fire and Earth energy interacts with your personal Day Master and solar-term month pillar to reveal your exact peak months for career, wealth, and love.

Western astrology reads one zodiac sign from your birth day. Saju builds a chart from four separate pillars — year, month, day, and hour — each with its own Heavenly Stem and Earthly Branch, for eight characters total ("Saju Palja"). It's a far more individualized system than a single sun sign.

Only the hour pillar needs it, and it changes roughly every two hours. Year/month/day pillars work from your date of birth alone. If you don't know your birth time, Heartloop still generates a reading from the other three pillars and flags which parts are time-sensitive.

Each category has a free basic reading. Deeper reports (career timing, wealth flow, detailed compatibility, etc.) unlock individually per report ($2.99 one-time) — there's no recurring subscription.
