"It is 5:30 now."
It's the ":30" part of "5:30". It means "half" - in telling time think of it as "half past".
It is the equivalent of "half past"
It is the equivalent of half past
Don't quote me on this, but I think it means "half" as in half an hour. So 5:30. :)
了 here would mean 'already' so 现在五点半了 would mean 'It is already 5 30' , which changes the meaning of the sentence
i don't know why but 现在五点半sounds unatural to me becuase I would usually say 现在是五点半am I wrong?
