Sekkicho: 72 Seasons Calendar

One painting for each turn of the year. Sekkicho is an almanac of China's 24 solar terms and 72 pentads (qīshí'èr hòu) — the five-day seasons ancient China used to read the year. In English and Chinese, every pentad follows the Yuan-dynasty "Collected Commentaries on the 72 Pentads" by Wu Cheng, and each has its own painting in the manner of Song-dynasty genre scrolls. ■ Now Today's pentad fills the screen: rivers flow; blossoms, leaves, rain and snow drift through the scene. Swipe up and the paper rises with: • The Collected Commentaries, in the original classical Chinese with English • Living with the season — rest, diet, mood and movement, drawn from the Huangdi Neijing and Gao Lian's "Eight Discourses on Nurturing Life" (cultural knowledge, not medical advice) • What people do — customs from the Jingchu Suishi Ji, Dongjing Menghua Lu and Mengliang Lu; anything without a classical source is marked "folk custom" • Seasonal table — foods of the season, each with its source • Today's almanac — Chinese lunar date, stems and branches, zodiac animal, moon age, Beijing sunrise and sunset ■ Scroll All 72 paintings joined into one handscroll. Drag through the year; past Greater Cold it rolls straight on into the Start of Spring, round and round. Drag the year bar to jump to any season. ■ Seals Press one seal for each pentad as it comes. Seventy-two seals make a year — your own seasonal book, kept only on your device. ■ Calendar A 2025–2032 calendar with Chinese lunar dates, stems and branches, zodiac animals, traditional festivals and Beijing sunrise and sunset, all reckoned in Beijing time. ■ Also • Home Screen and Lock Screen widgets • Optional pentad-change notices, scheduled on the device • English / 中文 / 日本語 (the Japanese interface shows Japan's own 72 seasons with Edo-period genre paintings) No account, no ads, no purchases, no data collection.
