A manseryeok engine that shows its work — solar-term month boundaries and true solar time correction, with every stem and branch traced to the rule behind it. Myohanmun computes the manseryeok (萬歲曆) — the traditional East Asian perpetual almanac that underlies the Four Pillars system — and shows its work. Most charting apps hand you a finished grid. Myohanmun shows the calculation behind it: which solar term your birth month actually falls under, how your birthplace longitude shifts your hour pillar, and which rule produced each stem and branch. ■ The calculation engine • Four Pillars chart — heavenly stems, earthly branches, five elements, ten gods, twelve stages, hidden stems • Solar-term (jieqi) month boundaries — the year turns at Ipchun, not on January 1 • True solar time correction — hour pillar adjusted for the longitude of your birthplace • Lunar/solar conversion with minute-level birth time entry • Every value traceable to the rule that produced it, not a black box ■ A chart you keep • Charts saved to your account and reopened at any time • Register family members and partners to compare charts side by side • Daily ganzhi (day pillar) reference, updated each day • Monthly calendar view of day pillars • Korean, English, Japanese, and Chinese (Simplified and Traditional) ■ Readings in prose Classical Myeongri texts are dense and unreadable without training. Myohan, the guide in this app, restates a computed chart in plain sentences — over 3,000 characters per topic, streamed as they are written, each statement pointing back to the chart element it came from. ■ Additional tools Two-chart comparison, auspicious date selection, name candidates weighted by element balance, career aptitude, life timeline across major and annual luck cycles, and multi-person charts for families and groups. ■ Premium (optional) • In-depth readings across 8 areas — love, marriage, wealth, career, health, study, relationships, family • Past, present, and future perspectives for each area • Monthly unlimited subscription for readings without per-item cost ■ Subscription details • Myohanmun Premium: monthly unlimited AI readings, billed as a monthly auto-renewing subscription • Price is shown on the App Store at the time of purchase; a discounted first month applies • Payment is charged to your Apple ID account upon purchase confirmation • Renews automatically unless cancelled at least 24 hours before the current period ends • Manage or cancel: device Settings > Apple Account > Subscriptions • Terms: https://myohanmun.com/terms • Privacy Policy: https://myohanmun.com/privacy ■ Privacy • Chart records are tied to your account only • Ads are non-personalized — the app does not track you across apps or websites • Complete deletion immediately upon account removal, and no sale of personal data Myeongri is a framework for self-understanding, not prediction. Readings are reference and cultural content; they do not substitute for medical, legal, or financial advice. Contact: contact@pantheonstudio.co.kr
