Jade Codex is a traditional Chinese almanac that knows your chart. Every day opens on a complete 黃曆 day page: the lunar date, the day's 干支 stem and branch, the 建除 day officer, the 值神 presiding spirit, the lunar mansion (二十八宿), the 彭祖百忌 caution, the clash animal, the auspicious directions, and the full 宜 and 忌 lists of what the day favors and what to avoid. All of it is computed on your iPhone. Solar-term instants come from Meeus astronomy; the 宜/忌 tables are reproduced from 《欽定協紀辨方書》, the Qing imperial almanac of 1741, which is in the public domain and cited inside the app on a Sources & Lineage screen. Nothing is invented, and nothing is sent anywhere. THE ALMANAC IS EVERYONE'S. THE READING IS YOURS. A printed almanac says the same thing to every reader. Yours doesn't have to. Enter your birth date and Jade Codex builds your Four Pillars chart (八字): Day Master, season, favorable element. Then it reads today against it: the day's recommendations ranked for you, each with one line saying why it fits. The same Tuesday is not the same Tuesday for everyone. FIND A GOOD DAY Planning a wedding, a move, a new venture, a haircut? Choose what you plan, and Jade Codex lists the coming 30 days the almanac favors for it, with the reason for each. Premium looks 90 days ahead and ranks the days for your chart. WHAT'S INSIDE • 黃曆 day page: 宜/忌, 建除, 值神, 二十八宿, 彭祖百忌, 沖煞, 喜神 and 財神 directions. Free, complete, and identical for every reader. • A morning almanac: one notification with the day's 宜 that opens today's page. With Premium and your chart, it names the one that suits you, and why. • Find a good day: more than 100 undertakings, from weddings and moving house to opening a business. • Four Pillars: your natal 八字 chart, ten gods, element balance, decade luck and the 流年 annual cycle. • I Ching: cast a hexagram with three coins; all 64 hexagrams and their changing lines. • Dream dictionary: 972 Chinese dream symbols in the 周公解夢 tradition. Describe a dream in your own words. • Codex: a linked reference of hexagrams, trigrams, stems, branches and the twenty-four solar terms. • Home Screen and Lock Screen widgets, a Control Center control, and Siri: "Today's element in Jade Codex." • A sticker pack: the eight trigrams, the twelve earthly branches, the five elements. • English, 简体中文, 繁體中文 and Español, each complete. Text grows to the largest accessibility sizes. PRIVATE BY CONSTRUCTION No account, no sign-in, no server. Your birth data never leaves your iPhone. The app is fully functional offline and with notifications turned off. JADE CODEX PREMIUM Premium unlocks the personal ranking on the day page, movement through past and future days, good days ranked for your chart 90 days ahead, the full daily breakdown, deeper chart readings, and unlimited follow-up questions. Everything Premium computes works on every iPhone with iOS 26; written readings of a cast or a dream use Apple Intelligence where your iPhone supports it. The almanac's own 宜/忌 columns stay free and complete: we sell the reading, not the reference. 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. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://jadewisdom.com/privacy/ An almanac is a reference, not an instruction. Read it the way an almanac has always been read: as one voice among several on what a day is like.
