Korean saju (BaZi) birth chart: daily horoscope, compatibility and good days.
Read full description
Today has a name. Saju, the Korean art of the Four Pillars of Destiny (BaZi), reads you from the year, month, day and hour you were born. Fourfold calculates your eight characters with care and tells you what they mean, one plain sentence at a time.
YOUR DAY, IN ONE LINE
Every morning, a short, blunt line made from your own chart and today's pillar. No vague promises. Something you can actually do today.
• Do and don't: three of each, for the day you're really having
• Why? Tap to see the reason in pictures, not jargon: fire melts metal, water feeds wood, and the animal of today against the day you were born
• Pick your voice: gentle, direct or blunt
• Share today's line as a clean square card
YOUR BIRTH CHART

PEOPLE AND COMPATIBILITY
Add a partner, a friend, family or a coworker and see what you are to each other.
