paipan: A Private Browser Toolkit for Chinese Calendars and Divination
A free, ad-free collection of Chinese calendrical and traditional divination tools, including lunar-calendar conversion, BaZi, Da Liu Ren, Qi Men Dun Jia, and Zi Wei Dou Shu.
Field notes
paipan separates its functionality into six browser tools, ranging from Gregorian/lunar conversion and a perpetual calendar to BaZi, Da Liu Ren, Qi Men Dun Jia, and Zi Wei Dou Shu charts. The calendar pages are described as including solar terms, festivals, stems and branches, and lunar dates, while chart tools expose systems such as four pillars, twelve palaces, stars, gates, and gods. Saved charts remain in the local browser, and the site says birth data is not uploaded.
