Six Lines: I-Ching & Almanac
Hexagram Study & Date Finder
Free · In‑App Purchases
Sima Qian read the sky, kept the calendar, and consulted the Changes as one discipline. Six Lines follows that tradition.
Every Chinese almanac app gives you star ratings for the day. The problem? Check two apps and they disagree. That's not a bug in those apps. It's a flaw in the whole approach.
The classical source text — the 1739 imperial Xieji Bianfang Shu, compiled for imperial use — says the same thing: generic day ratings are unreliable. The real system evaluates each activity separately. A day can be excellent for a wedding and terrible for moving house.
Six Lines follows the source.
CHINESE ALMANAC
Check what's auspicious and what to avoid today — for specific activities, with reasons. Lucky directions, star influences, and the Jianchu day quality cycle, all grounded in the source texts. Not star ratings. Not vibes.
I-CHING REFERENCE
All 64 hexagrams with three layers of commentary: original Chinese text, character-by-character gloss from the Bradford Hatcher matrix translations, and our own interpretive essays. Every line, judgment, and image rewards return.
Each hexagram is also paired with a public-domain masterpiece — painting, engraving, or literary work — and a short treatise exploring how it mirrors the hexagram's meaning. Art as a way in, not decoration.
The complete Yilin (Forest of Changes) is here too — one poetic verse for every possible hexagram transformation. All 4,096 are included, each with its own original ink brush artwork.
CASTING
Every reading begins with a tap. Choose between the traditional three-coin method or the authentic 49-stalk yarrow process. While your hexagram forms, artwork emerges alongside it — unique each time — creating space between question and answer.
STUDY GUIDANCE
Ask a question, cast a hexagram, and explore what the text says about your situation. The interpretation draws on traditional scholarship to offer perspective. Honest when the hexagram is severe.
SIX LINES STRUCTURAL ANALYSIS
Six Lines is named after Liu Yao (六爻) — the structural analysis system formalized by Jing Fang in the Western Han Dynasty. Each line is assigned a Five Element, a Six Relative role, and dynamic interactions based on the casting day. Six Lines computes the full najia plate: branch circle, hexagram plate, useful spirit, and element strengths — showing how classical scholars analyzed the relationships between lines, elements, and positions.
DATE FINDER
Planning a wedding? Opening a business? Dinner with friends? Find dates that align with your specific activity. See the reasoning — which stars support it, which conflicts to watch for — not just a thumbs up.
