What is the difference between 礼拜五 and 星期五 ?
Can they be used interchangeably?
There are three ways of saying week in Chinese.
禮拜 - this is the go to word in Taiwan.
星期 - this is the go to word here in Beijing, I'm not sure about the south.
週 - this is OK everywhere, but this is the most formal of the lot. If you read a formal newspaper, they will almost always use 週.
