时候 vs 时间 (shíhou vs shíjiān): time as occasion vs duration
时候 refers to a specific point in time or an occasion, as in 'when' something happens. 时间 refers to the duration of time, clock time, or time as a general concept. The key is to use 时候 for moments/events and 时间 for amounts or spans of time.
Both 时候 and 时间 are commonly used to express 'time' in Chinese, but they serve different functions. 时候 (shíhou) refers to a specific point in time or an occasion—answering the question 'when?'—and often appears in patterns like ...的时候 (when...). 时间 (shíjiān) refers to duration, a span of time, or the abstract concept of time—answering 'how long?' or 'how much time?'. Mixing them up leads to common grammatical errors, such as using 时候 to ask for a duration or 时间 to ask for a specific moment.
When to use each
Use 时候 to refer to a specific moment or occasion when something happens. It is often used in the structure ...的时候 (when...), and in question words like 什么时候 (what time/when). It can also be used in fixed expressions like 那时候 (at that time).
Use 时间 to refer to the duration of an activity, an amount of time, or the general concept of time. It appears in questions like 多少时间? (how much time?) and in statements about having free time (有时间) or needing time (需要时间). It can also be used to ask about clock time in formal contexts, though 几点了? is more common.
In some contexts, 时间 can refer to a point in time, such as 什么时间 (what time), but this is less common than 什么时候 for 'when'.

Examples
- 时候你什么时候来？Nǐ shénme shíhou lái?When are you coming?什么时候 asks for a specific point in time, using 时候.
- 时间请给我一点时间。Qǐng gěi wǒ yīdiǎn shíjiān.Please give me a little time.时间 refers to an amount/duration of time.
- 时候上课的时候不要说话。Shàngkè de shíhou bùyào shuōhuà.Don't talk during class....的时候 marks the occasion of class.
- 时间你每天有多少时间学习？Nǐ měitiān yǒu duōshao shíjiān xuéxí?How much time do you have to study every day?多少时间 asks for a duration.
- 时候那时候我还在上学。Nà shíhou wǒ hái zài shàngxué.At that time I was still in school.那时候 refers to a specific past point/occasion.
- 时间你还有时间吗？Nǐ hái yǒu shíjiān ma?Do you still have time/free time?有时间 means 'have free time' (duration), not a point.
Common mistakes
- Using 时候 to ask for a duration: '多少时候? (duōshao shíhou) – this is incorrect. Use 多长时间 or 多少时间.
- Using 时间 to ask 'when?': '你时间来? (nǐ shíjiān lái?) – this is incorrect. Use 你什么时候来?
- Confusing 有时间 (have free time) with 有时候 (sometimes). 有时间 is correct for 'have time', but 有时候 means 'sometimes' – they are different words.
- Using 时候 to ask clock time: '现在几点时候? (xiànzài jǐ diǎn shíhou) – incorrect. Use 现在几点了?
- Misplacing 时间 in expressions of duration: '我学习一个小时时间' (wǒ xuéxí yī gè xiǎoshí shíjiān) is redundant. The 时间 is usually omitted after specific duration phrases like 一个小时.
FAQ
- When do I use 时候 vs 时间?
- Use 时候 to talk about a specific point or occasion (e.g., 什么时候 'when', 吃饭的时候 'while eating'). Use 时间 to talk about duration or the concept of time (e.g., 多长时间 'how long', 没有时间 'no time').
- Can 时候 be used to ask 'how long'?
- No. 时候 only refers to points/occasions. For 'how long', use 多长时间 or 多少时间.
- Is 什么时间 the same as 什么时候?
- Not exactly. 什么时候 is the common way to ask 'when?'. 什么时间 also means 'what time' but is more formal and can emphasize the specific clock time, though 几点 is more common for clock time.
- Why can't I say '现在几点时候' for 'what time is it'?
- Because 时候 does not mean 'clock time'. For asking the time, use 几点了? (common) or 现在几点? (formal). 什么时间 can be used but sounds very formal.
