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.
