The news had something that happened on this date a few years ago(9-11) and it had in the title "Gestern-heute" if I remember correctly. What does it mean?
EDIT
To make the question clearer I am not looking for the meaning of "gestern" or "heute", but if putting them together has a meaning. I don't remember the sentence but it was talking about the 9-11 events in 2001.
