Etymology
Depicts a carved jade object, now written as 彫/琱. The meaning later shifted to "circumference" and "cycle". Later the 口 component was added when 周 was used to refer to a geographical region to indicate that the character was only "mouthed", i.e. used for its sound. In simplified Chinese 周 is also used to mean "week", while in traditional Chinese this meaning is written with a separate character 週.
About
The character 周 consists of an outer enclosure 冂 surrounding internal components: 土 (earth) and 口 (mouth). Its earliest forms, however, depicted a densely planted field divided into a grid. This original sense of density and thorough coverage, leaving no space unfilled, evolved to mean a complete circuit or full cycle. From this concept of a full rotation, it naturally came to represent a week, a full cycle in time.
