The word for week, 星期 (xīngqī), literally translates to “star period.” This name originates from the ancient system of naming the seven days of the week after the Sun, the Moon, and the five visible planets—the major celestial “stars” of the old world. Combining these characters, 这个星期 (zhè ge xīngqī) logically forms the meaning: “this [unit of] star-period,” or simply, “this week.”
While “this week” is a universal concept, its structure in Chinese reveals a key feature of the language: its logical and systematic nature. Unlike English, where days are named after Norse or Roman gods (Thursday = Thor's day), the Chinese days of the week are numbered. The week begins on Monday and follows a simple pattern:
This makes talking about specific days within 这个星期 very straightforward. For an English-speaking learner, this numbered system is often a welcome relief. The phrase 这个星期 itself functions almost identically to “this week” in English when planning or scheduling, making it an easy concept to grasp and use immediately.
这个星期 is a high-frequency phrase used in virtually all aspects of modern life. It is neutral in formality and appropriate for any situation.
