Structure of times (basic)

Times of the day in Chinese are formed with a number 1 to 12 (一 to 十二) followed by 点. This 点 is equivalent to o'clock in English. In China, people generally use a twelve hour clock, followed by 上午 (a.m.) or 下午 (p.m.) if necessary.

Some examples:

一点
两点
三点
十点
十二点下午

Note that two o'clock is 两点, not 二点. Also, 十二点下午 (12pm) is twelve noon / midday, as in English.

Half hours and quarter hours

Half and quarter hours are added after 点. A half hour is indicated with 半, and a quarter with 一刻. Some examples:

五点半
七点一刻
十一点一刻
两点半

Minutes

Minutes are marked with 分 (short for 分钟). The way to include them in the time depends on whether they're minutes past or to the hour.

Past the hour

Minutes past the hour are added after 点 in the same way as half and quarter hours. Examples:

一点四十分
两点十分
八点二十五分

To the hour

Minutes to the hour use this structure:

差 + minutes + 分 + hour + 点
