Meaning and Usage
"期間" (きかん) refers to a specific span or length of time during which something occurs or is valid. It is commonly used in both formal and informal contexts to indicate durations such as project timelines, contract terms, or event periods.
Common Collocations
- 期間中 (きかんちゅう): "during the period" — used to specify something happening within a set timeframe.
- 契約期間 (けいやくきかん): "contract period" — the duration of a contract.
- 期間限定 (きかんげんてい): "limited period" — often used in sales or promotions.
Usage Notes
When using 期間, it often pairs with counters like 日 (days), 週間 (weeks), or ヶ月 (months) to specify the length. It can also be combined with 中 (ちゅう) to emphasize something happening throughout the entire period. Avoid confusing 期間 with 時間, which generally refers to time in a more general or continuous sense rather than a defined span.
Register and Politeness
期間 is neutral and appropriate in both casual and formal speech, making it versatile for everyday conversation and business contexts.
