Rì chéng literally combines rì (‘day’ or ‘sun’) and chéng (‘journey’, ‘course’, or ‘progress’), evoking the idea of a day’s planned path or progression. As a noun, it refers to a structured plan of activities arranged by time—similar to ‘schedule’ or ‘agenda’ in English. It emphasizes order, timing, and intentionality, often implying official, professional, or formal planning rather than casual to-do lists.

This word is commonly used in work, academic, or event contexts—for example, describing a meeting agenda, a conference timetable, or a student’s daily study plan. While jiānchí (routine) stresses repetition and habit, rì chéng highlights temporal organization: what happens, and when. It can be modified by measure words like yí gè (one) or quantifiers like mánglù de (busy) or xìyǎn de (detailed), but never used as a verb or adjective on its own.
