K-Fortune brings Korea's traditional Four Pillars (Saju) system to ChatGPT — built by the team behind the #1 Saju custom GPT on the GPT Store, used by over 4 million people. Enter your birth date, time, and birth city — searchable from 160,000+ cities worldwide in any language — and instantly receive your full chart in a clean interactive card: Four Pillars (사주팔자), Five Elements balance, Ten Gods, Major Fortune cycles (대운), and Annual & Monthly Fortune. What sets K-Fortune apart is True Solar Time correction: your Hour Pillar is calculated from the sun's actual position at your birthplace, not standard clock time — the method traditionally regarded as the most rigorous in Myeongrihak (명리학). Solar-term boundaries are resolved to the exact minute, so charts born near a seasonal transition stay accurate. Explore your elemental balance, personality patterns, career and relationship themes, or the year ahead — as a framework for self-reflection rooted in centuries of Korean tradition. K-Fortune is a personal reflection app.
