• “The term ‘tea’ is used to describe different things. As far as the timing is concerned, however, I agree that there isn’t a fixed time for it – we normally have tea some time between 4 and 6, depending on what time we get home- but it is at some point between lunch and dinner.” [English – German Forums]
