What is Chinese Almanac?

The traditional Chinese calendar system that evaluates specific days for specific activities. Unlike Western calendars, the almanac assesses each day's suitability for activities like weddings, travel, construction, and business openings. Classical almanac practice evaluates activities individually (宜/忌) rather than assigning generic day ratings — a distinction the imperial Xieji Bianfang Shu makes explicitly.
