U+9031 "週" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
週
U+9031 "週" CJK Unified Ideograph-# is a Chinese, Japanese, and Korean ideograph that primarily means "week" or "cycle," commonly used in East Asian languages to denote a period of seven days. In Japanese, it is often read as "shū" and appears in words like "shūmatsu" for weekend, while in Chinese (traditional) it signifies a week or a full circuit. This character combines the radical for "movement" or "walk" (辵) with the phonetic component "周" (zhōu), which also conveys the idea of a cycle or circumference. Historically, it has been used in classical texts to refer to a complete turn or round, and it remains a fundamental element in modern calendars and scheduling across East Asian cultures.
