Jade Codex: Chinese Almanac

Jade Codex is a traditional Chinese almanac that knows your chart. Every day it opens on a complete 黄历 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 favours and what it does not. All of it is computed on your iPhone. Solar-term instants come from Meeus astronomy; the 宜/忌 tables are reproduced from 《钦定协纪辨方书》, 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, favourable element — then 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. WHAT'S INSIDE • 黄历 day page — 宜/忌, 建除, 值神, 二十八宿, 彭祖百忌, 冲煞, 喜神 and 财神 directions. Free, complete, and identical for every reader. • Four Pillars — your natal 八字 chart, ten gods, element balance, 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 周公解梦 tradition, searchable. • 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 and 简体中文 throughout. 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 personalised ranking on the day page, movement through past and future days, the full daily breakdown, deeper chart readings, and unlimited follow-up questions. The almanac's own 宜/忌 columns stay free and complete — we sell the reading, not the reference. Subscriptions are offered monthly and annually.

Read it the way an almanac has always been read — as one voice among several on what a day is like.
