Usage of 为期
The phrase 为期 is used to specify the duration of an event or activity, indicating how long it will last. It is commonly followed by a time period such as days, months, or years.
Common Collocations
- 为期 + 时间 (e.g., 为期三天): indicates the length of an event.
- 为期 + 时间 + 的 + 活动/会议/计划: describes the duration of a specific event or plan.
Notes
为期 is often used in formal or written contexts such as announcements, schedules, or reports. It emphasizes the fixed duration rather than the start or end date. Avoid confusing 为期 with 起止 (start and end), as 为期 focuses on the length of time.
Contrast
Unlike 期间 (qījiān), which can refer to any time within a period, 为期 specifically states the total length of the event or activity.
