"5:20" in Engpsh is pronounced as "five twenty."

The origin of this time-telpng convention comes from the traditional way of telpng time using a 12-hour clock. In this system, each hour is divided into 60 minutes, and the minutes are expressed as a combination of the hour and minutes. For example, 5:20 means five hours and twenty minutes past midnight or past noon.

Here are some example sentences in Engpsh and their Chinese translations:

I'll meet you at five twenty. (我五点二十分会见你。)
The movie starts at five twenty. (电影五点二十分开始。)
I usually wake up at five twenty. (我通常在五点二十分醒来。)
