Does ***Late Wednesday night*** mean `last Wednesday night` or `on Wednesday this week, but in the late night`? The translation tells me that the first explanation is right, but I cannot find a relative explanation in the dictionary.

The dictionary says: *late* is used to *refer to the part near the end of a period of time*, and has some examples:

>a late eighteenth century building

>in the late 1980s

So, which meaning is correct?
