Is today a good day? Jade Codex is a traditional Chinese almanac (黃曆, the tong shu) that answers from the day itself, and from your own chart. IS TODAY A GOOD DAY? Every day has a complete 黃曆 page: the full 宜 and 忌 lists, the 建除 day officer, the 值神 spirit, the lunar mansion, the 彭祖百忌 caution, the clash animal and the directions. Free, complete and the same for every reader. YOUR BAZI CHART, BY TRUE SOLAR TIME Enter your birth date for your Four Pillars chart (八字): Day Master, favorable elements and this year's 流年; Premium opens the ten gods and every decade-luck pillar. An exact birth time is corrected to true solar time for your birthplace. Then today is read against your chart: a tier for the day and a line on what to do. PICK A GOOD DAY A wedding, a move, a haircut? Choose from more than 100 undertakings and see the days in the next 30 that the almanac favors for it, each with its reason. Premium looks 90 days ahead and ranks the days for your chart. NEW IN 2.5: TRADITION AND THE CLOCK • Seek (求合): look for a moment on the Resonance Clock and set it to ring. • Watch for this: from Find a good day, a reminder on each fitting day. • Term letter (節氣信): a letter for each solar term. • Your month in the canon (月記): last month, kept as a scroll. • Widgets for A Line to Carry and the Pentad (七十二候), and lunar birth dates. ORIGINS Origins (源流) is a river of 29 turning points, from the Shang day count to the Qing almanac, in four lanes: Calendar, Changes, Birth and Dreams. Each claim is marked History records, Unearthed text, Scholars differ or Tradition says, and most turning points link to the part of the app they became. ALSO INSIDE • The Day Leaf (日箋): a page a day, free, with an evening stamp; share its line on a jade slip. • From the December solstice: the Nine Nines of Winter (九九消寒圖) and your year as a handscroll. • A leaf of its own for Start of Spring, Spring Festival, Lantern Festival and Awakening of Insects. • The Jade Codex Commentary: the received I Ching and all 384 line texts, with an original commentary. • I Ching: cast with three coins; read the received text and changing lines beside a modern rendering. • Your Chinese zodiac sign, and how this year's Tai Sui meets it. • 972 Chinese dream symbols in the 周公解夢 tradition. Describe a dream in your own words. • The Resonance Clock: the double hours, the 72 pentads and your birth on one wheel, with alarms by the double hour, dawn alarms and twelve 律 bells. • Widgets for the Home Screen, Lock Screen and StandBy, Control Center, Siri and Shortcuts. • English, 简体中文, 繁體中文 and Español, each complete, up to the largest text sizes. WHERE THE NUMBERS COME FROM Everything is computed on your device. Solar terms come from a table precomputed from NASA JPL's DE440 ephemeris. 宜/忌 come from a 通書 table; the day officer and clashes follow 《欽定協紀辨方書》 (Qing, 1741). The Sources & Lineage page names every source. PRIVATE BY CONSTRUCTION No ads, no account, no server. Your birth data never leaves your device. JADE CODEX PREMIUM Premium ranks each day for your chart, opens past and future days and good days 90 days ahead, reads your chart and every year ahead in depth, and adds unlimited casts, dream readings and chart questions, your lines of the year, returning notes and the full Resonance Clock. Written readings use Apple Intelligence, on the device, where supported. The 宜/忌 lists, the Commentary and Origins stay free. Subscriptions are offered monthly and annually. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel any time in your Apple Account settings.
