week

The word "week" names a unit of time made up of seven days, and it is one of the basic ways people organize life. Work, school, travel, sports, shopping, and rest are often planned around this repeating cycle. In many contexts, it means the calendar week, often understood as Monday through Sunday. In other cases, it simply means any span of seven days, as in "I was there for a week."

The idea is simple, but its use is broad. We talk about "next week," "last week," and "this week" to place events in time. We use it for routines and schedules: a workweek, a school week, a busy week, or a quiet week at home. It also appears in expressions about duration and experience, such as "for weeks," "once a week," or "a week later." In many situations, the word carries an emotional tone because it sums up how the last several days have felt: tiring, exciting, slow, or productive.

The word mainly works as a noun, but it also appears in compounds and related forms. "Weekend" refers to the end of the seven-day cycle in many cultures, usually Saturday and Sunday. "Weekly" describes something that happens every seven days or is connected to that rhythm, such as a weekly meeting or a weekly report. We also use "week" before another noun in phrases like "weeklong trip" or "week-old bread."

Although the seven-day pattern is now standard across much of the world, the way people experience it is not always the same. Some people think of it through work and rest, others through school, religion, or family routines. Whether someone is planning ahead, talking about the recent past, or measuring how long something lasted, "week" remains one of the most common and useful time words in English.
