Enter your birth date and see the full picture
Yin Chart, Yang Chart, Ten Major Stars, Twelve Supporting Stars, Tenchusatsu, phase relationships, annual timing — every element of your fate chart appears instantly, with no account required.
This is not a vague horoscope. It is a structural map based on classical natural philosophy, showing where you thrive, where friction tends to build, and when your timing shifts.
Timing cycles that explain why years feel different
Your chart is not static. Ten-year major cycles, annual rhythms, and daily waves interact with your birth structure, creating periods of flow and periods of friction.
Tenchusatsu is not bad luck — it is a natural phase when ordinary support loosens. The Calendar view shows these rhythms down to the day.

How is this different from fortune-telling?
FATE DECODER uses Yin-Yang Five Elements as a framework for self-understanding, not prediction. Yin-Yang Five Elements theory is a 2,500-year-old observational system — closer to a natural philosophy than to fortune-telling.
How does this relate to BaZi or Four Pillars?
They share a root, but they are not the same system. Both read the stem-branch calendar, and the ten stem-relationships line up one to one — what BaZi calls the Ten Gods, this method calls the Ten Major Stars. The structural difference is the count: BaZi means "eight characters" because it reads four pillars, including the hour of birth. This Japanese method reads three — year, month, and day — which is why no birth time is asked for here.
